TOTAL QUALITY MANAGEMENT – BA 913 UNIT-1(introduction to quality management) Definition: Total – Whole, entire, complete Quality – Excellence, class, meeting expectation Management – organising, administering, art of getting things done TQM is defined as both philosophy and a set of guiding principles that represent the foundation of continuously improving organisation. It is the application of quantitative methods and human resources to improve all the process within the organisation and exceed customer needs now and in the future. Total Quality Management is an effective system for integrating the quality development, quality maintenance and quality improvement efforts of various groups in an organization continuously, so as to enable marketing, engineering, production and service at the most economic levels which allow for full customer satisfaction. Historical Review of TQM Industrialisation led to mass production in which it led to the concept of one product at a time to the assembly line of production. Though workmanship was affected but mass production led to more job and reduction in cost of the product and increase in quality, reduction of defects etc. 1924 – After WWI, W.A. Sherwat of Bell Telephone statistical chart for the control of various. Concept of sample tests were followed. It was a failure in the initial stages. 1946 – ASQC American Society for Quality Control, now ASQ. Frequent meetings, conferences and publications were made to public. 1950 – W.Edwards Demings his guidance and lecture to Japan engineers transformed quality concepts in the organisation. His cycle ACT-PLAN-DO-CHECK 1954 – Joseph M.Juran Concept of efficient and productive. Juran Trilogy Quality planning – Quality Control – Quality Improvement 1960 – Quality control circles was formed. Zero defects concepts 1970 – Reactive approach to proactive approach. Shift from Japan to USA 1980 – SPC – Statistical Process Control. Concepts of parameter and tolerance. Experiments 1990 – Concepts of certification of ISO, CMM etc 2000 – six sigma concept - Six Sigma stands for Six Standard Deviations (Sigma is the Greek letter used to represent standard deviation in statistics) from mean. Six Sigma methodology provides the techniques and tools to improve the capability and reduce the defects in any process. TQM Basic Concepts 1. Management Involvement – Participate in quality program, develop quality council, direct participation 2. Focus on customer – who is the customer – internal and external, voice of the customer, do it right first time and every time. 3. Involvement and utilisation of entire work force – All levels of management 4. Continuous improvement – Quality never stops, placing orders, bill errors, delivery, minimise wastage and scrap etc. 5. Treating suppliers as partners – no business exists without suppliers. 6. Performance measures – creating accountability in all levels Barriers in TQM Implementation 1. Lack of commitment from top management – avoiding training for self and employees, meetings 2. Lack of employee involvement – particularly at managerial level, supportive attitude, trust 3. Lack of team work – Co-operation and co-ordination within workers. 4. Lack of customer oriented approach – Know the customer need, demand, taste, shortcomings 5. Lack of attention to feedback and complaints – 6. Supplier control – in terms of materials, cost, quality, delivery etc 7. Review quality procedures – up gradation, correct past errors. Learn from experience Einstein College of Engineering Five Pillars of TQM are, · Product · Process · System · People · Leadership Benefits of TQM : Customer satisfaction oriented benefits : 1. Improvement in product quality 2. Improvement in product design 3. Improvement in production flow 4. Improvement in employee morale and quality consciousness 5. Improvement in product service 6. Improvement in market place acceptance Economic improvement oriented benefits : 1. Reduction in operating costs 2. Reduction in operating losses 3. Reduction in field service costs 4. Reduction in liability exposure Principles of TQM : Visionary leadership Customer-driven excellence Organizational and personal learning Valuing employees and partners Agility Focus on the future Managing for innovation Management by fact Public responsibility Focus of results and creating values Systems perspective Quality – When a product or service meets or exceeds expectation considering the intended use and the selling price. Quality = performance / expectation Definition by ISO 9000:2000 It if defined as the degree to which a set of inherent characteristics fulfils requirement. Degree – good, excellent, bad Inherent – existing, within, natural Requirement – need or expectation Dimensions of quality 1. Performance 2. Features 3. Conformance 4. Reliability 5. Durability 6. Service 7. Response 8. Aesthetics 9. Reputation - Fulfilment of primary requirement Additional things that enhance performance Meeting specific standards set by the industry Consistence performance over a period of time Long life and less maintenance Ease of repair, guarantee, and warranty Dealer customer relationship, human interface exteriors, packages Past performance, ranking, branding Einstein College of Engineering Vision Statement: It is a short declaration of what an organization aspires to be tomorrow. It is the ideal state that might never reached but which you continuously strive to achieve. Example : We will be the preferred provider of safe, reliable, and cost-effective products and services that satisfy the electric-related needs of all customer segments. FLORIDA POWER & LIGHT COMPANY Mission Statement : The mission statements answers the following questions : Who we are ? Who are the customers ? What we do ? and How we do it ? It is the usually a one paragraph statement which describes the function of the organization. It provides a clear statement of purpose for employees, customers and suppliers. Example : To meet customers‘ transportation and distribution needs by being the best at moving their goods on time, safely and damage free. CANADIAN NATIONAL RAILWAYS Quality Policy: The Quality Policy is a guide for everyone in the organization as to how they should provide products and service to the customers. The common characteristics are Quality is first among equals. Meet the needs of the internal and external customers. Equal or exceed the competition. Continually improve the quality. Include business and production practices. Utilize the entire work force Customer perception of quality Before 1988 – Performance, Prize and service After 1989 – Performance, service and prize ASQ – American Society for Quality 1. Performance – availability (ready for use), reliability (free from failure), maintainability 2. Features – psychological and technical. Added feature along with main usage 3. Service – intangible, made up of many small things 4. Warranty – Vs guarantee. Customer feels comfortable with this 5. Price – value for money, ready to pay at the same time comparative study to be done 6. Reputation – Branding merges with quality. Good exp reaches 6 bad reaches 15 Service Quality Shift in focus from manufacturing industry to service industry and the services involved in manufacturing organization. Customer service is the set of activities an organization uses to win, attract and retain customers. It can be provided before, during and after the sale of the product. Elements of customer service Organization 1. Identify each segment – where the organization needs to concentrate on quality 2. Write down requirement – Proper documentation of quality policy in the form of a handbook 3. Communicate requirements – Inform its importance to all levels in the organisation 4. Organize process – create a systematic process as it is ongoing and never ending process 5. Organize physical spaces – aesthetics, atmosphere, room space, recreation, wifi etc Customer Care – Henry Ford – The boss just handles the cash it is the customer who pays your salary 1. Meet the customers expectation – treat all customers alike, respond quickly 2. Get the customer‘s point of view – think in the point of view of a customer 3. Deliver what is promised – keep up promise at any cost 4. Make the customer feel valued – customer must feel that due respect and importance is given to him 5. Respond to all complaints – minimize complaints and eradicate similar and repeated complaints Einstein College of Engineering Provide pleasant and knowledgeable enthusiastic employees 4. The Pareto effect is named after Vilfredo Pareto. Or in terms of quality improvement. Some people equated quality cost with the cost of attaining quality. Write document in customer friendly language – simple and point blank Front-line people – The people who have first and direct contact or interaction with the customer 1. some people equated the term with the extra incurred due to poor quality. dealers and suppliers. Provide clean and comfortable reception area – cleanliness. a) Internal failure costs .Nordstorm example obsess with the customer Leadership 1. billing etc 3. it could be used to estimate uncertain events in the past. Categories of Quality Cost : Many companies summarize quality costs into four broad categories.Employee retention is proportional customer retention Quality cost: During the 1950‘s the concept of ―Quality Cost‖ emerged. Pareto analysis is a statistical technique in decision making that is used for selection of a limited number of tasks that produce significant overall effect. c) Appraisal costs . Optimize trade off between time and personal attention 2. Challenge them to develop better methods – small changes in packing. Analysis technique for Quality Cost The term "trend analysis" refers to the concept of collecting information and attempting to spot a pattern. the term "trend analysis" has more formally-defined meanings. body language etc 6. Pareto Analysis This fact gave rise to the Pareto effect or Pareto‘s law: – ‗the vital few and the trivial many‘. using co product 2.External research must be done to feel the pulse of the customer . Recognize and reward performance .It is the final result of customer satisfaction and customer loyalty . Like having food . Listen to front line people 3.Most cases what customer says or feels may vary from actual consumption or purchase . an economist and sociologist who lived from 1848 to 1923. Make sure they are adequately trained – written and oral communication. Although trend analysis is often used to predict future events. It uses the Pareto principle . dress code. weather etc Communication – All forms of communication written. Hire people who like people – train groom them 2. b) External failure costs . Different people assigned different meanings to the term. d) Prevention costs . Einstein College of Engineering . But.6. advt. in the information. such as how many ancient kings probably ruled between two dates. a large majority of problems (80%) are produced by a few key causes (20%). In some fields of study. web site must prove quality 1. Serve them as internal customers 5.The cost incurred in keeping failure and appraisal costs to a minimum. Over-respond to customer – make him feel he is cloud nine 7.The cost incurred in determining the degree of conformance to quality requirement. based on data such as the average years which other known kings reigned. Strive for continuous process improvement Customer Retention . verbal.the idea that by doing 20% of work you can generate 80% of the advantage of doing the entire job.

They are. the widely accepted thing is ―Quality cost is the extra cost incurred due to poor or bad quality of the product or service‖. Lead by example – spend time with all level.The cost associated with defects that are found prior to transfer of the product to the customer. free gifts etc 4. Give them authority to solve problems – give discounts. Minimize the number of contact points – channels and levels 3. Carry out the change or test (preferably on a small scale). 13.and cumulative percentage on y-axis Step 5: Join the above points to form a curve Step 6: Plot (on the same graph) a bar graph with causes on x. Create constancy of purpose and continual improvement Adopt the new (Japanese) philosophy – by management and workers alike. Its objective is to separate the 'vital few' from the 'useful many. In this phase.Pareto analysis is a formal technique useful where many possible courses of action are competing for your attention. 6. It can be used to guide the entire improvement project It can be used to develop specific projects once target improvement areas have been identified. Do not depend on (quality) inspection – build quality into the product and process Choose quality suppliers Improve constantly – to reduce variation in all aspects Training on the job – for workers and management. 9. 5.a change or a test. Then drop the line at the point of intersection with the curve on x-axis. the problem-solver estimates the benefit delivered by each action. not just meet targets. Use of Pareto principle in prioritizing or ranking a range of items which have different levels of significance. Implement the change you decided on in the plan phase. and later adopted by W. encourage employees Break down internal barriers – department‘s are ―internal customers‖ Eliminate slogans (exhortations) – processes make mistakes not people. Eliminate fear – encourage two-way communication. 4. To identify these areas for change consider using a Flow chart or Pareto chart Do . aimed at improvement. In essence. This point on the x-axis separates the important causes (on the left) and trivial causes (on the right) UNIT-2(PRINCIPLES AND PHILOSOPHIES OF QUALITY MANAGEMENT) Demings 14 Points Summarised 1. 14. Step 2: Arrange the rows in the decreasing order of importance of the causes (i. 7. The model provides a framework for the improvement of a process or system. 10.' Steps to identify the important causes using Pareto analysis Step 1: Form a table listing the causes and their frequency as a percentage. Edwards Deming.e. analyze what you intend to improve. Eliminate numerical targets – management by objectives not numbers Remover barriers to worker satisfaction – including annual appraisals Encourage self improvement and education for all Everyone is responsible for continual improvement in quality and productivity – particularly top management PDCA Cycle – PLAN > DO > CHECK > ACT The PDCA (or PDSA) Cycle was originally conceived by Walter Shewhart in 1930's. Document the procedure and observation Einstein College of Engineering . looking for areas that hold opportunities for change. Leadership not supervision – to get people to do a better job. then selects a number of the most effective actions that deliver a total benefit reasonably close to the maximal possible one. 2. 11. 3. 12. The first step is to choose areas that offer the most return for the effort you put in-the biggest bang for your buck. Plan . 8. the most important cause first) Step 3: Add a cumulative percentage column to the table Step 4: Plot with causes on x.and percent frequency on y-axis Step 7: Draw line at 80% on y-axis parallel to x-axis. Einstein College of Engineering . was difficult to adhere to. Step 2: Write the problem statement on the right hand side of the page. This quality concern is now the effect. or run the cycle again. Juran Trilogy The Trilogy consists of three sequential and logical groups of activities: – Quality Planning – Quality Control – Quality Improvement All three processes are universal – Applied to a particular process – Performed by top management or by middle management Juran Trilogy: A systematic and comprehensive system for break-through quality improvements Quality Defined: meet customer needs and freedom from deficiencies Trilogy Components – Quality Planning – discover customer needs and deficiencies and design adequate processes – Quality Control -. After planning a change.the attainment of unprecedented levels of performance Cause-and-Effect Diagrams . you must decide whether it is worth continuing that particular change.compare actual performance to goals and take action on the differences – Quality Improvement -. However. you must determine how well it is working. implementing and then monitoring it.Adopt the change. or even led to no improvement.the results. abandon it. or slightly increasing your complexity. Run Charts can be helpful with this measurement. or causes. of problems. If it consumed too much of your time. and draw a box around it with an arrow running to it. Kaoru Ishikawa at the University of Tokyo Purpose: One important part of process improvement is continuously striving to obtain more information about the process and it's output.1943 by Mr. Act . Use tools to collect information Check or Study . you may consider aborting the change and planning a new one. This sends you back into the Plan phase and can be the beginning of the Ramp of Improvement. if the change led to a desirable improvement or outcome. but also can lead us to the root cause. After you have implemented the change for a short time. Team members knowledgeable about the quality. Team members focus on the problem under investigation. Constructing the Cause-and-Effect Diagram: Step 1: Select the team members and a leader. you may consider expanding the trial to a different area. Cause-and-effect diagrams allow us to do not just that. What was learned? What went wrong? This is a crucial step in the PDCA cycle. Is it really leading to improvement in the way you had hoped? You must decide on several measures with which you can monitor the level of improvement. and not rooting out any defects in processes. that the prime responsibility for poor quality lies with management. Improved Quality 2.. Instead. Management commitment it: the need for quality improvement must be recognized and accepted by management. high. Increase the opportunity for innovation 5." What that means is that a product should conform to the requirements that the company has itselfestablished based on its customers' needs. Both must accept the evaluation in terms of quality and service 7. Identify.work should be seen as a series of activities or processes. bad. good. Management sets the tone for thequality initiative from the top. and is often summarized as the "Fourteen Steps. Nonconforming products are ones that management has failed to specify or control. Shared vision CONTRIBUTIONS OF CROSBY: Crosby's approach to quality was unambiguous. its related sub-causes that might affect our quality concern or problem (our Effect). He also believed." 1. check sheets. The more information we have about our processes the better we are at improving them. the meaning of quality is "conformance to requirements. price. The team members generate ideas as to what is causing the effect. Both should think in the shoes of the end user. Lower cost 4. Proper understanding in quality. for each main cause. but that companies should notbegin with "allowances" or substandard targets with mistakes as an inbuilt expectation. Always check to see if all the factors contributing to the problem have been identified. quantity. In his view. A quality policy is needed which states that ".Step 3: Brain-storming. Systems that allow things to go wrong and thatresult in those things having to be done again can cost organizations between 20% and 35% of their revenues. and low quality are meaningless concepts in the abstract. Step 4: This step could be combined with step 3. Trust 3. not with the workers. defined by clear requirements andcarried out to produce identified outcomes. Step 5: Focus on one or two causes for which an improvement action(s) can be developed using other quality tools such as Pareto charts. and other gathering and analysis tools. Both should strive for mutual satisfaction and good relationship 10.. The cost of nonconformance equals the cost of not doing it right first time. His seminal approach to quality was set out in Quality is Free. Contracts must be signed so the disputes can be settled amicably 8. Long-term commitment 2.each individual is expected to perform exactly like the requirement or cause the requirement to be officially changed to what we and the customer Einstein College of Engineering . delivery and payments 5. Customer and supplier must be independent and interdependent 3. "Zero defects" does not mean that people never make mistakes. in Crosby's estimation. Increase efficiency 3. Conclusion: Improvement requires knowledge. Supplier must satisfy the customer need 6. Quality improvement equates to profit improvement. who then draw up a quality improvement program with an emphasis on the need for defect prevention. Start by asking why the problem exists. Partnering Benefits 1. The customer must provide clear information to the supplier 4. Customer and supplier fully responsible for quality control 2. Both must have exchange of information to improve quality and service 9. Cause-and-effect diagrams are one quality tool that is simple yet very powerful in helping us better understand our processes Ten Principles of Customer/Supplier Relationship 1. Continuous improvement of product and service Key Elements in Partnering 1. 2. these comprise 30-. People need to see that problems are regularly being resolved. step in the progress of an organization toward quality. The performance standard is zero defects. Quality councils: the quality professionals and team leaders should meet regularly to discuss improvements and upgrades to the quality program. Imai has held lectures on KAIZEN. This means establishing and recording quality measures for each area of activity in order to show where improvement is possible and where corrective action is necessary. which was established in Switzerland (1985) to help companies introduce KAIZEN® concepts. The cost of quality evaluation: the cost of quality is not an absolute performance measurement. any problems that prevent them from carrying out error-free work. The quality improvement team: representatives from each department or function should be brought together to form a quality improvement team. one-page form. Crosbyadvocated delegation of this task to the people who actually do the job. Goal setting: all supervisors ask their people to establish specific. 7. measurable goals that they can strive for. The act of recognition itself is what is important. The measurement of quality is the price of nonconformance CONTRIBUTIONS OF MASAAKI IMAI: Masaaki Imai is Founder of KAIZEN Institute (KI). and the provision of visible evidence of the results of a concern for quality improvement. Lean and other related management subjects. 3. as well as having Einstein College of Engineering . but an indication of where the action necessary to correct a defect will result in greater profitability. 12. thus setting the stagefor defect prevention on the job. Its members should be people who have sufficient authority to commit the area they represent to action. starting with zero defects day. or even the key. Crosby stresses that this sharing process is a key. Usually. 3. Quality awareness: this involves making employees aware of the cost to the company of defects. KI (also now known as KAIZEN Institute Consulting Group. and that everyone gets the same message in the same way.KICG) has offices in over 30 countries around the globe. should make a lasting impression as a "new attitude" day. and 90-day goals. 4. Over the last 30+ years. Doing it over again: during the course of a typical program lasting from 12 to 18 months. 5. Supervisor training: all managers should undergo formal training on the Fourteen Steps before they are implemented. 10. Error cause removal: employees are asked to describe. 9. Quality measurement: the status of quality should be determined throughout the company. Zero defects day. and tools. turnover and change will dissipate much of the educational process. Zero defects day: it is important that the commitment to zero defects as the performance standard of the company makes an impact. Managers should understand each of the Fourteen Steps well enough to be able to explain them to their people. 11. Corrective action: discussion of problems will result in the finding of solutions and also bring to light other elements that are in need of improvement. where it really counts. 13. through training and information. Corrective action should then become a habit. systems." 2. It is important to set up a new team of representatives and begin the program again from the beginning. 4. on a simple. when supervisors explain the program to their people.really need. Recognition: it is important to recognize those who meet their goals or perform outstanding acts with a prize or award. The system of quality is prevention. 6. Problems should be acknowledged and begin to be addressed within 24 hours by the function or unit to which th begin to grow more confident that their problems will be attended to and dealt with. although this should not be in financial form. The definition of quality is conformance to requirements. This "starting over again" helps quality to become ingrained in the organization CROSBY‘S four absolutes of quality: 1. Establishing an ad hoc committee for the zero defects program: zero defects is not a motivation program: its purpose is to communicate and instill the notion that everyone should do things right first time. 14.

Accountability for quality: Because quality is everybody's job. an engineering firm that designs and installs operational systems. often based on customer surveys and feedback. The concept of quality costs TAGUCHI’S CONTRIBUTION: Genichi Taguchi is a Japanese quality expert. Taguchi received formal recognition for his work including Deming Prizes and Awards. Imai‘s role has been oneof integrating various KAIZEN management practices. known for the Quality Loss Function and for methodologies to optimise quality at the design stage – ―robust design‖. such as Just-in-time. as Japanese believe that good process will deliver good results. incremental but constant." The concept of a "hidden" plant—the idea that so much extra work is performed in correcting mistakes that there is effectively a hidden plant within any factory. KAIZEN Institute dispatches both local and global consultants. Europe and other strategic locations where best practices can be found. KAIZEN Institute regularly sponsors KAIZEN Tours. who are corporate managers and academics and considered experts in the various technicalities of KAIZEN.D. Kaizen is defined as making ―continuous improvement‖ . Einstein College of Engineering . Feigenbaum wrote several books and served as President of the American Society for Quality (1961-1963). Western way of pragmatic approach ―why-fix-it-if-it-ain‘t-broke‖ Kaizen extends a more optimistic philosophical view: ―Everything—even if it ain‘t broke—can be made better!‖ "kai― > Means "change" or "the action to correct" "zen― > means "good― Importance is given to the process not the results. TQM. warranty claims and ultimately reduced market share. it may become nobody's job—the idea that quality must be actively managed and have visibility at the highest levels of management. and TPM.consulted with global companies (outside of Japan) and assisting them in their process of introducing change and continual improvement. from MIT. Genichi Taguchi's Quality Loss Function The Quality Loss Function gives a financial value for customers' increasing dissatisfaction as the product performance goes below the desired target performance. and is now President and CEO of General Systems Company of Pittsfield.slow. . CONTRIBUTION OF FEIGENBAUM: Armand Vallin Feigenbaum (born 1922) is an American quality control expert and businessman.into the cultural environment of client companies. downtime. and quality improvement efforts of the various groups in an organization so as to enable production and service at the most economical levels which allow full customer satisfaction. Feigenbaum received a bachelor's degree from Union College. He devised the concept of Total Quality Control. to various assignments to work closely with the local KAIZEN consultants. including cost of scrap. Genichi Taguchi considers quality loss all the way through to the customer. Mr. it gives a financial value for increasing costs as product performance goes above the desired target performance. He was Director of Manufacturing Operations at General Electric (1958-1968). His contributions to the quality body of knowledge include: "Total quality control is an effective system for integrating the quality development. within Japan. Equally. Seiri. Unimportant or uncontrollable ―noise‖ factors have negligible impact on the product performance and can be ignored. People involved in Seiri must not feel sorry about having to throw away things.involves creating a working prototype 2. It provides a practical method for dealing with the real problems that workers face every day. System design . With Genichi Taguchi‘s Robust Design methodologies you would set up experiments that would test a range of combinations of factors . number of eggs. It promotes daily activity for continuous improvement. not quality through inspection. If your business makes cookies from raw ingredients. with long and short cooking time. Taguchi breaks the design process into three stages: 1. temperature of butter. high and low oven temperature. Even the number of necessary items in the workplace must be kept to its absolute minimum. Tolerance design . Parameter design . Robust Design of Cookies This is easier explained by example. and unrelated materials in the workplace. for example oven temperature affects cookie quality more than the number of eggs. Taguchi‘s Robust Design methodologies allow the designer through experiments to determine which factors most affect product performance and which factors are unimportant. and lean manufacturing efforts. cooking time. such as total preventive maintenance. The idea is to ensure that everything left in the workplace is related to work. SEIRI / SORT / CLEANUP: The first step of the "5S" process. The 5S framework is an extension of Hirano's earlier works on just-in-time production systems. The designer can focus on reducing variation on the important or critical factors.for example. 5S PRINCIPLES: The 5S framework was originally developed by just-in-time expert and international consultant Hiroyuki Hirano. baking tray material etc. The cookies resulting from each of these trials would be assessed for quality.involves experimenting to find which factors influence product performance most 3.amount of flour. The 5Ss represent a simple "good housekeeping" approach to improving the work environment consistent with the tenets of Lean Manufacturing System.involves setting tight tolerance limits for the critical factors and looser tolerance limits for less important factors. It fosters efficiency and productivity while improving work flow. there are many possible factors that could influence the quality of the cookie . pollution prevention. With this knowledge you would design a process that ensures the oven maintains the optimal temperature and you would be able to consistently produce good cookies. etc. Quality through Robust Design Methodology Taguchi methods emphasised quality through robust design. And it fits with a facility's other efforts. unnecessary.The quality loss function allows financial decisions to be made at the design stage regarding the cost of achieving the target performance. A statistical analysis of results would tell you which the most important factors are. Einstein College of Engineering . 1 or 2 eggs. It encourages a proactive approach that prevents problems and waste before they occur. refers to the act of throwing away all unwanted. just-in-time manufacturing. safety initiatives. heat of oven. Separate needed items from unneeded items. tools. and equipment. Its objective includes. 4. It would be a good idea to have every area of the workplace assigned to a person or group of persons for cleaning. Use special designed cart to organize tools. 3. In performing Seiri. Every single item must be allocated its own place for safekeeping. instruments. the needed items can be easily found. the third step in "5S". Remove unneeded items from working areas. Use see-through cover or door for visibility. 7. A place for everything and everything in its place. Store similar items together. 2. Store items needed by most people in a common storage area. or orderliness. measuring devices. stored and retrieved. Store items only needed by each individual in his/her own working area. 9. Cleaning must be done by everyone in the organization. SEITON / SET IN ORDER / ARRANGING: Seiton. etc.There are two main objectives of Seiri. follow these guidelines: 1. Einstein College of Engineering . SEISO / SHINE / NEATNESS Seiso. as well as returned in that same place quickly.. 6. Use rack or shelf if possible. 4. Organize working / storage area. 7. including work pieces. is all about efficiency. Use small bins to organize small items. 8. Don't stack items together. says that 'everyone is a janitor. 8. Its objective includes.always thinking if it is clean enough to make a good impression. jigs. and the worker becomes productive. In performing Seiton. but a whole attitude that includes ensuring everything is in perfect condition. First-in first-out (FIFO). 5. Remove all excess items from working areas. and save space and time. 5. supplies. cleanliness ensures a more comfortable and safe working place. Seiso is not just cleaning. Different items in separate rows. 6. cleanliness will lead to visibility so as to reduce search time and cleanliness ensures a higher quality of work and products. 9. Everyone should see the 'workplace' through the eyes of a visitor . Store items not Item not needed now. work flow becomes efficient. Use red tag to get rid of unneeded items. Follow these guidelines in performing Seiso: 1. personal items. that are needed for each particular machine. this simple guideline is a must: 1. Place tools and instructional manual close to the point of use.' Seiso consists of cleaning up the workplace and giving it a 'shine'. Use dust collecting covers or devices to prevent possible dirt or reduce the amount of dirt. and each location must be labeled for easy identification of what it's for. Discard the items never used. from operators to managers. 3. Clearly label each item and its storage areas (lead to visibility). first is the simplification of tasks and effective use of space. This step consists of putting everything in an assigned place so that it can be accessed or retrieved quickly. supports efficiency and productivity. Use color for quickly identifying items. If everyone has quick access to an item or materials. 2. Seiketsu encompasses both personal and environmental cleanliness. without having to be reminded by management. Operators clean their own equipment and working area and perform basic preventive maintenance. fumes. Personnel must therefore practice 'seiketsu' starting with their personal tidiness. broken. Rather than worry about what fits into Seiri and what fits into Seiton. Quality Circle concept has three major attributes: Einstein College of Engineering . 5. attitude and feelings. lighting.

CONCEPT The concept of Quality Circle is primarily based upon recognition of the value of the worker as a human being. experience. as someone who willingly activises on his job. Visual management is an important ingredient of seiketsu. Removing used. or surplus items from the work area 2. Investigating the causes of dirtiness and implement a plan to eliminate the sources of dirt. Colorcoding and standardized coloration of surroundings are used for easier visual identification of anomalies in the surroundings. Keep everything clean for a constant state of readiness. SEIKETSU / SYSTEMIZE / DISCIPLINE: The fourth step of "5S". cables. It consists of defining the standards by which personnel must measure and maintain 'cleanliness'. steam. personnel voluntarily observe cleanliness and orderliness at all times. It is "a way of capturing the creative and innovative power that lies within the work force". spills. Shitsuke. Wearing safe working apparel and using safe equipment 7. Checking that items are where they should be 4. It is based upon the human resource management considered as one of the key factors in the improvement of product quality & productivity. more or less translates to 'standardized clean-up'.' It denotes commitment to maintain orderliness and to practice the first 4 S as a way of life. and electricity SHITSUKE / SUSTAIN / ON-GOING IMPROVEMENT: The last step of "5S". water. The emphasis of shitsuke is elimination of bad habits and constant practice of good ones. 3. air. and other aspects of the workplace environment 3. or seiketsu. Listening to the "voice" of the process and being alert to things such as unusual noises 5. his wisdom. The characteristic of 5S tends to overlap significantly rather than cover very different subjects. 4. Minimizing all waste and the use of valuable resources such as oil. QUALITY CIRCLE Quality Circle is a small group of 6 to 12 employees doing similar work who voluntarily meet together on a regular basis to identify improvements in their respective work areas using proven techniques for analysing and solving work related problems coming in the way of achieving and sustaining excellence leading to mutual upliftment of employees as well as the organisation.

Examples of variables data are elapsed time. proportion) of measurements of a quality characteristic in samples taken from the process at different times [the data] The mean of this statistic using all the samples is calculated (e. yes/no. These ―count‖ data may be expressed as pass/fail. mean of the ranges. or presence/absence of a defect. the mean of the means. In the following. the characteristic of controls (constant or variable sample size): The p-chart: it is a control chart for fraction nonconforming The c-chart: it is a control chart for number of defects or nonconformities The u-chart: it is a control chart for number of nonconformities per unit It is so to choose the best adapted control chart to the production. Step 6 .Calculate the grand mean of the subgroup’s average. Attributes concern quality characteristics which are able to be classified in two types. the formula for the value plotted on the p-chart is: pi ^ Di ni ^ Di n The central line and control limits are computed as shown bellow: pi ^ Central line p m ^ i 1 pi n Limits UCL p 3 p (1 p) n LCL p 3 p (1 p ) n Einstein College of Engineering . Their use depends on the production (which quality characteristic to control. where p : fraction of nonconforming D : number of nonconforming units in the ith sample n : sample size of the ith sample In general. This fraction is called ―p‖. For a constant sample size Mathematical notions If the sample size is constant.Calculate UCL for ranges Step 9 . conform and not conform to specifications. Step 5 .Step 4 . What is called nonconforming means that the unit controlled is not conformed to standard on one or more of examined quality characteristics.Calculate average of subgroup ranges Step 7 . how many to examine).Document the chart Control Charts for attributes When the quality controls have to focus on a quality characteristic hard or expensive to measure on a numerical scale.Calculate UCL and LCL for subgroup averages Step 8 . we focus of number of nonconforming units or nonconformities in a population. 1. Three types of charts exist. m samples of n units are tested but the sample size can be either constant or variable. the control chart for attributes are a useful alternative. The grand mean of the subgroup‘s average (X-Bar) becomes the centerline for the upper plot. we study both cases. Use the following formula to calculate the range (R) for each subgroup. The goal of control charts for variable is still to control mean and variability of a process but here.Calculate and enter the range for each subgroup.Select scales and plot Step 10 . The p-chart: Control chart for fraction nonconforming The focus of the chart is the ratio of the number of nonconforming units in a population over the total number of units in this population. To construct the p-chart. In this case again. The c-chart: Control chart for number of nonconformities observed The focus of the chart is the number of nonconformities in a population. m samples of n units are controlled and the sample size can be constant or not. For a constant sample size Mathematical notions The central line and control limits are computed as shown bellow: Central line c m i 1 c m Limits UCL c 3 c LCL c 3 c The u-chart: Control chart for number of nonconformities per unit The u.

This team will typically include people from a variety of functional groups. especially those which occur at a late stage. and are therefore sensitive. Many of the service companies surveyed (32%) were also using QFD. There is also some reluctance among users of QFD to publish and share information . QFD is sometimes referred to by other 'nicknames' . History The creation of QFD is generally attributed to Mitsubishi's Kobe shipyard in Japan. consensus. and more frequent design cycles mean that products can be improved more rapidly than the competition reduced overall cost due to reducing design changes. the best ways to do it. Strengths and weaknesses of QFD Einstein College of Engineering . Applied through the Kaizen philosophy under Total Quality Control. Specific design applications in Japan range from home appliances and clothing to retail outlets and apartment layouts. the best order to accomplish the tasks proposed and the staffing and resources required to enhance customer satisfaction. and precision machinery (66%). In the USA the first serious exponents of QFD were the 'big three' automotive manufacturers in the 1980's.much more so than with other quality-related methodologies. service. The method on which QFD is implemented may have a large impact on benefits derived and companies should take up QFD only after getting the consent and commitment of the team members. QFD provides a systematic approach to build a team perspective on what needs to be done. and production the identification of 'holes' in the current knowledge of the design team the capture and display of a wide variety of important design information in one place in a compact form support for understanding. Benefits of QFD The main 'process' benefits of using QFD are: improved communication and sharing of information within a cross-functional team charged with developing a new product. it is not a short-term answer to product development problems. such as marketing. The original approach. especially when complex relationships and trade-offs are involved the creation of an informational base which is valuable for repeated cycles of product improvement The main 'bottom line' benefits of using QFD are: greater likelihood of product success in the marketplace. This is a powerful benefit: customer requirements are less likely to have changed since the beginning of the design project.gleaned from many sources. conceived in the late 1960's. the uptake of QFD in the Western world appears to have been fairly slow. and decision making. There has been no survey comparable to the JUSE study regarding the spread of QFD in North America. However. was adopted and developed by other Japanese companies. When to use QFD QFD is a powerful tool that leads to significant improvements in product/process performances. process engineering. due to the precise targeting of key customer requirements reduced overall design cycle time. procurement. sales. electronics (63%). product engineering. and a few leading companies in other sectors such as electronics. compared with other methodologies such as Benchmarking. reduced product cost by eliminating redundant features and over-design. as well as the design parameters chosen for the new product. construction (82%). In 1986 a study by the Japanese Union of Scientists and Engineers (JUSE) revealed that 54% of 148 member companies surveyed were using QFD. It is also a good format for capturing and recording/documenting decision making. or the House of Quality (from the characteristic house shape of a QFD chart).the voice of the customer (from its use as a way of communicating customer needs). which are not only time consuming but very costly. However. QFD is the most highly developed form of integrated product and process development in existence. The sectors with the highest penetration of QFD were transportation (86%). and valuable to competitors. proprietary. notably Toyota and its suppliers. In this way they provide a solid foundation for further improvement in subsequent design cycles. This may be because the data captured and the decisions made using QFD usually relate to future product plans. and there are relatively few sources of literature and case studies. distribution.

After ranking the severity. corrosion or deformation. From these controls an engineer can learn how likely it is for a failure to be identified or detected. Hereafter one should identify testing. actions are considered to change the design by eliminating the failure mode. First. Examples of failure effects are: degraded performance. Risk Priority Numbers (RPN) are calculated. but which occur more often and are less detectable. In this way it is convenient to write these effects down in terms of what the user might see or experience. A failure effect is defined as the result of a failure mode on the function of the system as perceived by the user. Again this should be in technical terms. It is widely used in the manufacturing industries in various phases of the product life cycle and is now increasingly finding use in the service industry as well. After these 3 basic steps. noise or even injury to a user. it is necessary to test their efficiency. This number represents the ability of planned tests and inspections at removing defects or detecting failure modes. Step 3: Detection When appropriate actions are determined. Effects analysis refers to studying the consequences of those failures. This step is called the detailed development section of the FMEA process. and can be potential or actual. The proper inspection methods need to be chosen. These numbers help an engineer to prioritize. Examples of causes are: erroneous algorithms. Once this is done it is easy to determine the areas of greatest concern. Actions need to be determined if the occurrence is high (meaning >4 for non safety failure modes and >1 when the severity-number from step 1 is 9 or 10). Therefore each failure mode should be listed in technical terms and for function. occurrence and detectability the RPN can be easily calculated by multiplying these 3 numbers: RPN = S x O x D This has to be done for the entire process and/or design. A severity rating of 9 or 10 is generally reserved for those effects which would cause injury to a user or otherwise result in litigation. A failure mode is given a probability number(O). Also a design verification is needed. Each effect is given a severity number(S) from 1(no danger) to 10(important). A failure cause is looked upon as a design weakness. Each combination from the previous 2 steps. They are more threshold values in the evaluation of these actions. Risk Priority Numbers RPN do not play an important part in the choice of an action against failure modes. There could be less severe failures. design. Step 2: Occurrence In this step it is necessary to look at the cause of a failure and how many times it occurs. Step 1: Severity Determine all failure modes based on the functional requirements and their effects. Fewer engineering changes Reduces design process Leads to teamwork Consensus decision Everything is preserved in writing Failure modes and effects analysis (FMEA) is a procedure for analysis of potential failure modes within a system for the classification by severity or determination of the failures' effect upon the system. or item especially ones that affect the customer. receives a detection number(D). The failure modes that have the highest RPN should be given the highest priority for corrective action. It is important to note that a failure mode in one component can lead to a failure mode in another component. if possible. This can be done by looking at similar products or processes and the failures that have been documented for them. This means it is not always the failure modes with the highest severity numbers that should be treated first. If the severity of an effect has a number 9 or 10. that prevent failure modes from occurring or which detect the failure before it reaches the customer. Examples of failure modes are: Electrical short-circuiting. or protecting the user from the effect. excessive voltage or improper operating conditions. Failure causes are any errors or defects in process. Hereafter the ultimate effect of each failure mode needs to be considered. All the potential causes for a failure mode should be identified and documented. an engineer should look at the current controls of the system. analysis. Timing of FMEA Einstein College of Engineering .again 1-10. monitoring and other techniques that can be or have been used on similar systems to detect failures. Additionally. Seven tools of Quality I . the multiplication of the severity. so they must prioritize.Pareto chart: Italian economist Vilfredo Pareto Shows on a bar graph which factors are more significant. This helps avoid the same failures in future projects. and minimize or eliminate those effects.The FMEA should be updated whenever: At the beginning of a cycle (new product/process) Changes are made to the operating conditions A change is made in the design New regulations are instituted Customer feedback indicates a problem Uses of FMEA Development of system requirements that minimize the likelihood of failures. Purpose: The purpose of the Pareto chart is to prioritize problems No company has enough resources to tackle every problem. This method helps to find the vital few contributing maximum impact. II . The ordinal rankings only say that one ranking is better or worse than another. Development of methods to design and test systems to ensure that the failures have been eliminated. The reason for this is that the rankings are ordinal scale numbers. Einstein College of Engineering . capture engineering knowledge Reduce the potential for warranty concerns Early identification and elimination of potential failure modes Emphasis problem prevention Minimize late changes and associated cost Catalyst for teamwork and idea exchange between functions Disadvantages If used as a top-down tool. or to report expected failure intervals of particular failure modes up to the upper level subsystem or system. Purpose: Flow Charts provide a visual illustration of the sequence of operations required to complete a task. reliability and safety of a product/process Improve company image and competitiveness Increase user satisfaction Reduce system development timing and cost Collect information to reduce future failures. Ensuring that any failure that could occur will not injure the customer or seriously impact a system. It is not able to discover complex failure modes involving multiple failures within a subsystem.Flowchart: A technique that separates data gathered from a variety of sources so that patterns can be seen (some lists replace "stratification" with or "run chart"). As you begin using the Pareto chart to decide where your problems are." or an "8" may not be twice as bad as a "4. but not by how much. a ranking of "2" may not be twice as bad as a ranking of "1. FMEA may only identify major failure modes in a system. For instance. Fault tree analysis (FTA) is better suited for "top-down" analysis. doing something. Also called the 20-80 rule. Evaluation of the requirements of the customer to ensure that those do not give rise to potential failures. you will discover many things about your processes and will come because you will know where to improve. he determined that a small percentage of any given group (20%) account for a high amount of a certain characteristic (80%). occurrence and detection rankings may result in rank reversals. and multiplication is not a valid operation on them. When used as a "bottom-up" tool FMEA can augment or complement FTA and identify many more causes and failure modes resulting in top-level symptoms. Tracking and managing potential risks in the design. Advantages Improve the quality." but multiplication treats them as though they are. Conclusion: The most important thing in improving quality is to start somewhere. where a less serious failure mode receives a higher RPN than a more serious failure mode. Pareto Principle: The Pareto concept was developed by the describing the frequency distribution of any given characteristic of a population. Identification of certain design characteristics that contribute to failures. Second. time. and draw a box around it with an arrow running to it. Step 2: Write the problem statement on the right hand side of the page. Flow charts can be drawn in many styles.etc. for each main cause.1943 by Mr. we need to define the type of data that is going to be collected. Identify. It provides the user with a graphical representation of the amount of variation found in a set of data. The more information we have about our processes the better we are at improving them. its related sub-causes that might affect our quality concern or problem (our Effect). V. Constructing the Cause-and-Effect Diagram: Step 1: Select the team members and a leader. There is no right or wrong way to draw a flow chart.. check sheets. It is always a desire to produce things that are equal to their design values. Input ---------------------Process----------------Output III . Step 4: This step could be combined with step 3. Kaoru Ishikawa at the University of Tokyo Purpose: One important part of process improvement is continuously striving to obtain more information about the process and it's output. and other gathering and analysis tools..

This quality concern is now the effect.Cause-and-Effect Diagrams .. and countable data such as the number of defects. Team members focus on the problem under investigation. Start by asking why the problem exists. The true test of a flow chart is how well those who create and use it can understand it. This collected data needs to be accurate and relevant to the quality problem. Always check to see if all the factors contributing to the problem have been identified. Team members knowledgeable about the quality..Histograms Purpose: To determine the spread or variation of a set of data points in a graphical form. of problems.

Seven New Management and Planning Tools In 1976. the roles played by various individuals. while the range chart indicates the amount of spread or variability around the nominal design value. Range = Largest point . the Union of Japanese Scientists and Engineers (JUSE) saw the need for tools to promote innovation. communicate information and successfully plan major projects. A tally sheet is usually used to find the frequency of data points in each interval. Calculate the number of data points (frequency) that are in each class. need to be collected Calculate the range of the sample data: The range is the difference between the largest and smallest data points. helping you move your thinking step by step from generalities to specifics. often called the seven management and planning (MP) tools. Control charts is one SPC tool that enables us to monitor and control process variation. Matrix diagram: shows the relationship between two. Scatter Diagrams: A scatter diagram is a nonmathematical or graphical approach for identifying relationships between a performance measure and factors that might be driving it.

When a strong relationship is present. and generally easy to interpret. 2. or measurements. the center line CL. or simply the seven management tools. 3. the average and range control charts. 4. Conclusion: Histogram is simple tools that allow the user to identify and interpret the variation found in a set of data points. VII . A control chart has basically three line: the upper control limit UCL.Scatter Diagrams Purpose: To identify correlations that might exist between a quality characteristic and a factor that might be driving it. No relationship Conclusion: Scatter diagrams allow the user to graphically identify correlations that could exist between a quality characteristic and a factor that might be driving it. It is a quality tool that is simple. three or four groups of information and can give information about the relationship. Their are three basic types of relationships that can be detected to on a scatter diagram: 1. The first deals with how close the process is to the nominal design value. VI . Calculate the size of the class interval. If no relationship can be detected.smallest point. It is important to remember that histograms do not give solutions to problems. the change in one item will automatically cause a change in the other. Einstein College of Engineering . Not all the tools were new. Affinity diagram: organizes a large number of ideas into their natural relationships. The class interval is the width of each class on the X axis.Constructing a Histogram: The following are the steps followed in the construction of a histogram: Data collection: To ensure good results. Positive relationship 2. Identifying the tolerance level in the variations. such as its strength. A team researched and developed the seven new quality control tools. It is calculated by the following formula: Class interval = Range / Number of classes. Tree diagram: breaks down broad categories into finer and finer levels of detail. A minimum of 25 points is required for a control chart to be accurate. or samples. Types of variation Common and Special Cause Variation Control charts: Developed in the mid 1920's by Walter Shewhart of Bell labs. There are two basic types of control charts. a minimum of 50 data points. easy to communicate to others. The seven MP tools.Control Charts Purpose: Process is in control and to monitor process variation on a continuous basis. Interpreting the Results: Once all the data points have been plotted onto the scatter diagram. and generally easy to interpret. This graphical approach is quick. and the lower control limit LCL. you are ready to determine whether their exists a relation between the two selected items or not. but their collection and promotion were. Six differently shaped matrices are possible: L. Process decision program chart (PDPC): systematically identifies what might go wrong in a plan under development. 6. understanding. Affinity Diagram This tool takes large amounts of disorganized data and information and enables one to organize it into groupings based on natural relationships. a prioritization matrix is an L-shaped matrix that uses pairwise comparisons of a list of options to a set of criteria in order to choose the best option(s). Y. Activity Network Diagram This tool is used to plan the appropriate sequence or schedule for a set of tasks and related subtasks. 7. It can be used to break down broad general subjects into finer and finer levels of detail. The diagram enables one to determine the critical path (longest sequence of tasks). Matrix data analysis: a complex mathematical technique for analyzing matrices. The process of creating an interrelationship diagraph helps a group analyze the natural links between different aspects of a complex situation. Interrelationship Diagraph This tool displays all the interrelated cause-and-effect relationships and factors involved in a complex problem and describes desired outcomes. such as its strength. and potential scheduling and resource problems and their solutions. It was created in the 1960s by Japanese anthropologist Jiro Kawakita. careful and timeconsuming of decision-making tools. Tree Diagram This tool is used to break down broad categories into finer and finer levels of detail. using a Tree Diagram. Matrix Diagram This tool shows the relationship between items. It uses a combination of tree and matrix diagraming techniques to do a pair-wise evalutaion of items and to narrow down options to the most desired or most effective. the best schedule for the entire project. depending on how many groups must be compared. Einstein College of Engineering . the roles played by various individuals or measurements. Prioritization Matrix This tool is used to prioritize items and describe them in terms of weighted criteria. and contingency actions. T. the FMEA also rates relative risk levels for each potential failure point. and adapting outstanding practices from other organizations considered to be best-in-class. Different shaped boxes are used to highlight risks and identify possible countermeasures (often shown as 'clouds' to indicate their uncertain nature). (See also PERT diagram.) Benchmarking is the process of measuring an organization's internal processes then identifying. At each intersection a relationship is either absent or present.5. Arrow diagram: shows the required order of tasks in a project or process. The PDPC is similar to the Failure Modes and Effects Analysis (FMEA) in that both identify risks. X. It then gives information about the relationship. It is used when subtasks must occur in parallel. One of the most rigorous. Process Decision Program Chart (PDPC) A useful way of planning is to break down tasks into a hierarchy. C and roof-shaped. consequences of failure. The PDPC extends the tree diagram a couple of levels to identify risks and countermeasures for the bottom level tasks. often replaced in this list by the similar prioritization matrix. It can map levels of details of tasks that are required to accomplish a goal or task. Developing the tree diagram helps one move their thinking from generalities to specifics. To whom or what will we compare? Business-to-business. The Benchmarking process The formal 10-step benchmarking process is shown in outline below. The analysis phase must involve a careful understanding of your current process and practices. positive or parity. It helps crack through resistance to change by demonstrating other methods. Recognize that benchmarking is a process not only of deriving quantifiable goals and targets. The result is often a business case for making changes in order to make improvements. There‘s an infinite variety of ways to obtain required data – and most of the data you‘ll need are readily and publicly available. Benchmarking must be conducted against the best companies and business functions regardless of where they exist. 2. time or quality of what one organization does against what another organization does. Ask: Is this other organization better than we are? Why are they better? By how much? What best practices are being used now or can be anticipated? How can their practices be incorporated or adapted for use in our organization? Answers to these questions will define the dimensions of any performance gap: negative. direct competitors are certainly prime candidates to benchmark. ―The systematic process of comparing an organization‘s products. Planning. What is to be benchmarked? Every function of an organization has or delivers a ―product‖ or output. What is desired is an understanding of internal performance on which to assess strengths and weaknesses. The essential steps are those of any plan development: what. But they are not the only targets. an order. Einstein College of Engineering ." Benchmarking is the process of comparing the cost. who and how. The gap provides an objective basis on which to act—to close the gap or capitalize on any advantage your organization has. How will the data be collected? There‘s no one way to conduct benchmarking investigations. ideas and tools to improve their effectiveness. an invoice. as well as those of the organizations being benchmarked. but more importantly. Allows employees to visualise the improvement which can be a strong motivator for change Helps to identify weak areas and indicates what needs to be done to improve. a service or a report. whether it‘s a physical good. a shipment. it‘s the process of investigating and documenting the best industry practices. Benchmarking is appropriate for any output of a process or function. The benchmarking process consists of following phases: 1. systematic process of evaluating and comparing the capability of one organization with others normally recognized as industry leaders. which can help you achieve goals and targets."Benchmarking: A continuous." Benchmarking opens organizations to new methods. services and practices against those of competitor organizations or other industry leaders to determine what it is they do that allows them to achieve high levels of performance. for insights for optimizing the organizations processes. Analysis.‖ (Society for Human Resources Management) Advantages of benchmarking Benchmarking is a powerful management tool because it overcomes "paradigm blindness. Convert benchmark findings. Communicate findings to all organizational levels to obtain support. Progress toward benchmark findings must be reported to all employees. Benchmarking becomes institutionalized and is done at all appropriate levels of the organization. Finance and Accounting and Information and Communication Technology are unlikely to be directly comparable in cost and efficiency terms and may need to be disaggregated into processes to make valid comparison Poka-yoke is a Japanese term that means "fail-safing" or "mistake-proofing". not by specialists. This type is usually not industry specific meaning it is best to look at other industries.the initiating firm focuses its observation and investigation of business processes with a goal of identifying and observing the best practices from one or more benchmark firms. Financial benchmarking . It involves careful planning to incorporate new practices in the operation and to ensure benchmark findings are incorporated in all formal planning processes.allows the initiator firm to assess their competitive position by comparing products and services with those of target firms. correcting. Integration is the process of using benchmark findings to set operational targets for change. by Shigeo Shingo as part of the Toyota Production System. More broadly. This process can sometimes involve reverse engineering which is taking apart competitors products to find strengths and weaknesses. essential and self-initiated facet of the management process. Integration. Performance benchmarking . Put in place a periodic measurement and assessment of achievement. and the term adopted. Develop action plans. Functional benchmarking . and an ongoing reporting mechanism. Einstein College of Engineering . thus ensuring superiority. increasingly applied to back-office processes where outsourcing may be a consideration. commitment and ownership. 4. Use the creative talents of the people who actually perform work tasks to determine how the findings can be incorporated into the work processes. but as this means "fool-proofing" (or "idiotproofing") the name was changed to the milder poka-yoke. Action. Steps include: Gain operational and management acceptance of benchmark findings.the process of designing new products or upgrades to current ones. and operational principles based on them. Activity analysis will be required where the objective is to benchmark cost and efficiency. Strategic benchmarking . Its purpose is to eliminate product defects by preventing. or drawing attention to human errors as they occur.a company will focus its benchmarking on a single function in order to improve the operation of that particular function. Product benchmarking . Maturity will be reached when best industry practices are incorporated in all business processes.performing a financial analysis and comparing the results in an effort to assess your overall competitiveness. Clearly and convincingly demonstrate findings as correct and based on substantive data. Maturity. would a knowledgeable businessperson prefer it? Do other organizations benchmark your internal operations? Maturity also is achieved when benchmarking becomes an ongoing. Complex functions such as Human Resources. the term can refer to any behavior-shaping constraint designed into a product to prevent incorrect operation by the user. to specific actions to be taken. Types of Benchmarking Process benchmarking . Any plan for change also should contain milestones for updating the benchmark findings.3. A poka-yoke is any mechanism in a lean manufacturing process that helps an equipment operator avoid (yokeru) mistakes (poka). 5. Tests for superiority: If the now-changed process were to be made available to others.involves observing how others compete. It was originally described as baka-yoke. The concept was formalised. The contact method identifies product defects by testing the product's shape.Implementation in manufacturing Poka-yoke can be implemented at any step of a manufacturing process where something can go wrong or an error can be made. a jig that holds pieces for processing might be modified to only allow pieces to be held in the correct orientation. inspection. size.

The motion-step (or sequence) method determines whether the prescribed steps of the process have been followed. Shingo argued that errors are inevitable in any manufacturing process. By eliminating defects at the source. 2. or the poka-yoke device actually prevents the mistake from being made.

Time and cost constraints – period of the process. For example. People in companies that have implemented TQM are more likely to have the basic understanding necessary for implementing EDM/PDM. Attempts to implement TQM often fail because top management doesn't lead and get committed instead it delegates and pays lip service. The customer. fast response.that aims to provide. Once it is recognized that customer satisfaction can only be obtained by providing a high-quality product. `being sensitive to customer requirements' goes beyond defect and error reduction. continuous improvement. Customer satisfaction is seen as the company's highest priority. and to management and employee remuneration. In the TQM context. Many companies have difficulties in implementing TQM. The company believes it will only be successful if customers are satisfied. productivity. when you look at successful companies you find a much higher percentage of successful TQM implementation. and people involved with customers it's much easier to introduce EDM/PDM in a company with a TQM culture than in one without TQM. methods and performance measures for achieving those goals. and in creating and deploying well defined systems. The Engineering Department is a supplier to downstream functions such as Manufacturing and Field Service. continuous improvement of the quality of the product is seen as the only way to maintain a high level of customer satisfaction. actions based on facts. It has to be introduced and led by top management. Commitment and personal involvement is required from top management in creating and deploying clear quality values and goals consistent with the objectives of the company. As a result many people are sceptical about TQM. operating as a customer to some functions and as a supplier to others. don't focus on the second-rate companies who can't handle TQM. and has to treat these internal customers with the same sensitivity and responsiveness as it would external customers. Some useful messages from results of TQM implementations: if you want to be a first-rate company. As well as recognizing the link between product quality and customer satisfaction. not internal activities and constraints. look at the world-class companies that have adopted it the most effective way to spend TQM introduction funds is by training top management. competitiveness or financial return. and continue to provide. to customer requirements and satisfaction. However. and merely meeting specifications or reducing customer complaints. and a TQM culture. Surveys by consulting firms have found that only 20-36% of companies that have undertaken TQM have achieved either significant or even tangible improvements in quality. top management leadership and commitment. TQM leadership from top management TQM is a way of life for a company. with things being done right first time. TQM also recognizes that Einstein College of Engineering . These systems and methods guide all quality activities and encourage participation by all employees. but also those that enhance and differentiate them for competitive advantage. directly or indirectly. employee participation. This is a key point. people involved in new product development. Continuous improvement Continuous improvement of all operations and activities is at the heart of TQM. comes first. Customer-driven quality TQM has a customer-first orientation. The concept of requirements is expanded to take in not only product and service attributes that meet basic requirements. The TQM company is sensitive to customer requirements and responds rapidly to them. its customers with products and services that satisfy their needs. The culture requires quality in all aspects of the company's operations. Each part of the company is involved in Total Quality. and defects and waste eradicated from operations. they are more likely to view EDM/PDM as an information and workflow management system supporting the entire product life cycle then as a departmental solution for the management of CAD data Important aspects of TQM include customer-driven quality. The development and use of performance indicators is linked. They are not going to feel this if they are excluded from the development of visions. This implies that all activities include measurement and monitoring of cycle time and responsiveness as a basis for seeking opportunities for improvement. they are generally discovered and resolved before they can get to the next internal customer. whether it be of shop floor data.product quality is the result of process quality. When problems do occur within the product development process. This implies short product and service introduction cycles. Simplicity is gained through concurrent product and process development. communicate more effectively. The TQM approach is based on the use of objective data. and are not caused by particular employees. Improvement cycles are encouraged for all the company's activities such as product development. If the right information is not available. A TQM culture It's not easy to introduce TQM. act creatively. errors can't be identified. then the analysis. They are unlikely to behave in a responsible way if they see management behaving irresponsibly . Actions based on facts The statistical analysis of engineering and manufacturing facts is an important part of TQM. can't take place. The customer-driven approach helps to prevent errors and achieve defect-free production. strategies. or engineering test results. Without a TQM approach. An open. As a result. and provides a rational rather than an emotional basis for decision making. Short-term results drive behavior so scrap. and an emphasis on quality at the design stage. The result is a dramatic improvement in the elapsed time from product concept to first shipment. Facts and analysis provide the basis for planning. work-arounds. there is a focus on continuous improvement of the company's processes. In practice. Employee participation A successful TQM environment requires a committed and well-trained work force that participates fully in quality improvement activities. Fast response To achieve customer satisfaction. the company has to respond rapidly to customer needs. improvement of operations. Such participation is reinforced by reward and recognition systems which emphasize the achievement of quality objectives. Product development in a TQM environment is customer-driven and focused on quality. and fire-fighting is necessary and rewarded. and the way customer relationships are managed. Employees have to be made to feel that they are responsible for customer satisfaction. These can be achieved with customer-driven and processoriented product development because the resulting simplicity and efficiency greatly reduce the time involved. On-going education and training of all employees supports the drive for quality. and so errors can't be corrected. and innovate. Usually these people are not managers but workers in the process. There is also a strong emphasis on prevention rather than detection. TQM links remuneration to customer satisfaction metrics. Efficiencies are realized from the elimination of non-value-adding effort such as re-design. As people behave the way they are measured and remunerated. Employees are encouraged to take more responsibility. product development is usually carried on in a conflictual atmosphere where each department acts independently. and to an increase in customer satisfaction. This will lead to an improvement in process quality. cooperative culture has to be created by management. waste. changes. review and performance tracking. Management focuses on supervising individuals. Teams are Einstein College of Engineering . Product development in a TQM environment Product development in a TQM environment is very different to product development in a non-TQM environment. The statistical approach to process management in both engineering and manufacturing recognizes that most problems are systemrelated. and plans. and comparison of performance with competitors.saying one thing and doing the opposite. In turn this will lead to an improvement in product quality. data is collected and put in the hands of the people who are in the best position to analyze it and then take the appropriate action to reduce costs and prevent non-conformance. It's important they participate in these activities. use of EDM/PDM. Elimination of waste is a major component of the continuous improvement approach. and rework are normal practice. Benefits of employee involvement: Employee Involvement improves quality and increases productivity because Employees make better decisions using their expert knowledge of the process. They train and coach rather than direct and supervise. Employees are better able to accept change because they control the work environment. Motorola (1988). Therefore. They encourage collaboration rather than competition. Texas Instruments (1992) and Xerox (1989).process-oriented. Employees are more likely to implement and support decisions they had a part in making. Employees have an increased commitment to unit goals because they are involved. They establish organizational system to support quality effort. They continuously improve communication. and interact with their internal customers to deliver the required results. Intelligence f. They learn from the problems. a more accurate predictive capability should be valuable in improving group performance. IBM (1990). rather than control subordinates.‖ Six traits on which leaders tend to differ from non leaders are: a. They choose suppliers in the basis of quality not price. Awards for Quality achievement The Deming Prize has been awarded annually since 1951 by the Japanese Union of Scientists and Engineers in recognition of outstanding achievement in quality strategy. LEADERSHIP: Leadership plays a central part in understanding group behavior. for it is the leader who usually provides the direction toward goal attainment. and rewarding teamwork. Self-confidence e. Job-relevant knowledge. We can define leadership as ―the ability to influence a group toward the achievement of goals. Milliken (1989). Employees are better able to take immediate corrective action. Ambition and energy b. management and execution. They encourage and recognize team effort. Characteristics of Quality Leaders: They continuously evaluate the changing customer needs. Employee involvement increases morale by creating a feeling of belonging to the organization. EMPLOYEE INVOLVEMENT Employee involvement is a means to better meet the organization‘s goals for quality and productivity at all levels of an organization. They empower. Employees are better able to spot and pinpoint areas for improvement. Honesty and integrity d. Desire to lead c. Since 1988 a similar award (the Malcolm Baldrige National Quality Award) has been awarded in the US. Einstein College of Engineering . Management's focus is on controlling the overall process. Employee involvement reduces labor management hassle by more effective communications and cooperation. They continuously committed to quality. They emphasize improvement rather than maintenance They emphasize prevention. Early winners of the Baldrige Award include AT&T (1992). EMPOWERMENT Empowerment means invest people with authority. e) Determine the performance measures of the organization and monitor. g) Establish multifunctional project and work group teams and monitor their progress. the confidence. c) Create a total education and training plan. production. The typical quality council meeting agenda of a well established TQM organization : a) Progress reports on teams b) Customer satisfaction report c) Progress on meeting goals d) New project teams e) Recognition dinner f) Benchmarking report Recognition is a form of employee motivation in which the organization publicly acknowledges the positive contributions an individual or team has made to the success of the organization. marketing. h) Establish and revise the recognition and reward system to account for the new way of doing business. Everyone must understand the need for change. Recognition and reward go together to form a system for letting people know they are valuable members of the organization. It is the driver for the TQM engine. Reward is something tangible to promote desirable behavior. Quality Council : In order to build quality in the culture. a quality council is established to provide overall direction. and quality. In a typical organization the quality council is composed of the chief executive officer (CEO). finance. The system needs to change for the new paradigm iii. Empowerment is an environment in which people have the ability. ii. The organization must enable its employees. mission and quality statement of the organization. with the input from all the personnel. Duties of the quality council: a) To develop the vision. Its purpose is to tap the enormous reservoir of creativity and potential contribution that lies within every worker at all levels. and a Coordinator or consultant. Einstein College of Engineering . f) Continuously determine those projects that improves and affect external and internal customer satisfaction. d) Determine and continuously monitor the cost of poor quality. The three conditions necessary to create the empowered environment are: i. and the commitment to take the responsibility and ownership to improve the process and to initiate the necessary steps to satisfy customer requirements within well-defined boundaries in order to achieve organizational values an goals. b) To develop strategic long-term plan with goals and annual quality improvement program with objectives. the senior managers of the functional areas. such as design. Organization Standards c.‖ This means that the Software product delivered should be as per the requirements defined. The Scope of the effort is also clearly defined. Quality Control: Once the software components are built the results are monitored to determine if they comply with the standards. Project Requirements Using these as Inputs the Quality Planning process creates a plan to ensure that standards agreed upon are met. The data collected helps in measuring the performance trends and as needed help in identifying defective pieces of code.o o o INTRODUCTION TO SOFTWARE QUALITY The definition of the ISO 8204 for quality: ―Totality of characteristics of an entity that bears on its ability to satisfy stated and implied needs. Quality Plan Einstein College of Engineering . 1) Quality Planning : Quality Planning is the most important step in Software Quality Management. Standards defined for the Project b. Scope of Work f. The starting point for the Planning process is the standards followed by the Organization. The inputs for the Planning are as summarized as follows: a. the Organization and the means to achieve them. The key processes of Software Quality Management fall into the following three categories: 1) Quality Planning 2) Quality Assurance 3) Quality Control The Software Quality Management comprises of Quality Planning. We shall now take a closer look at each of them. It is very important to have processes that evaluate the project performance and aim to assure that the Quality standards are being followed and the final product will be in compliance. Relevant Industry Standards d. In other words the Software Project would meet the clients expectations. Quality Assurance : Once the standards are defined and we start building the product. This is expressed in the Quality Policy and Documentation defining the Organization-wide standards. Proper planning ensures that the remaining Quality processes make sense and achieve the desired results. Hence the outputs of the Quality Planning process are: a. Software Quality Management : Software Quality Management simply stated comprises of processes that ensure that the Software Project would reach its goals. Using these as inputs the Standards for the specific project are decided. We now examine a few more terms used in association with Software Quality. Quality Assurance and Quality Control Processes. Company‘s Quality Policy b. Sometimes additional industry standards relevant to the Software Project may be referred to as needed. Regulations e. Quality Planning: In the Planning Process we determine the standards that are relevant for the Software Product. Many software shops fail to document the project at various levels. It includes prevention costs. b. 2) Quality Assurance : The Input to the Quality Assurance Processes is the Quality Plan created during Planning. If a different person or a team is responsible for future installations they may end up making mistakes during installation. If there were an error. This may lead to poor ―Software Quality‖ as the product does not meet the expectations. Other tools: There are various other tools used in the Planning process such as Cause and Effect Diagrams. All these help us to create a Quality Management Plan for the project. Once again consider a scenario where a tester fails to document the test results after executing the test cases. Cost of Quality: This includes all the costs needed to achieve the required Quality levels. Changes to the Development process may be done if necessary. If the work done meets the standards defined then the work done is accepted and released to the clients.To create these outputs namely the Quality Plan various tools and techniques are used. Quality Audits and various other techniques are used to evaluate the performance of the project. thereby failing to deliver as promised. Steps: In a typical Software Development Life Cycle the following steps are necessary for Quality Management: 1) Document the Requirements 2) Define and Document Quality Standards 3) Define and Document the Scope of Work Einstein College of Engineering . . Cause and Effect Diagrams may also be used here.Quality Standards defined for the Project . Hence documentation is the key for future analysis and all Quality Management efforts. These tools and techniques are huge topics and Quality Experts dedicate years of research on these topics. System Flow Charts.Quality Management Plan. Consider a scenario where the Requirements of the Software Project are not sufficiently documented. as required. Hence the testing team would not be able test the software developed for these expectations or requirements. Cost Benefit Analysis. Design of Experiments: Using statistics we determine what factors influence the Quality or features of the end product c. etc. We would briefly introduce these tools and techniques in this article. Similarly consider a scenario where the development team does not document the installation instructions. The tools and techniques used in the Planning Process such as Design of Experiments.Actual Observations and Measurements of the Work done or in Progress The Quality Control Processes use various tools to study the Work done. a. If the Work done is found unsatisfactory it may be sent back to the development team for fixes. 3) Quality Control : Following are the inputs to the Quality Control Process: . This may lead to confusion later. we would not be sure at what stage the error was introduced in the software at a component level or when integrating it with another component or due to environment on a particular server etc. Benchmarking: The proposed product standards can be decided using the existing performance benchmarks of similar products that already exist in the market. Importance of Documentation: In all the Quality Management Processes special emphasis is put on documentation. This helps us to ensure that the Project is following the Quality Management Plan. appraisal costs and failure costs. d. In this case it is quiet possible that the client has a set of expectations and the tester may not know about them. 4) Document the Software Created and dependencies 5) Define and Document the Quality Management Plan 6) Define and Document the Test Strategy 7) Create and Document the Test Cases Execute Test Cases and (log) Document the Results 9) Fix Defects and document the fixes 10) Quality Assurance audits the Documents and Test Logs Einstein College of Engineering .
