  • 1. Introduction to Quality Management 1© Oxford University Press 2008. All rightsreserved.
  • 2.  Quality has a longer history in out lives than 2 both cost and productivity.  It is regarded as more „human‟ concept than either cost or productivity.  The problem of the producer is that the number of customer may be too large, each one may have a different perception of quality.  If third party such as quality certification agency has to decide about the quality of product or service , its perception may be different from customer and the producer.© Oxford University Press 2008. All rightsreserved.
  • 3. Definitions 3 According to the Oxford Dictionary for the Business World: Quality is defined as the degree of excellence. Quality Guru J M Juran defined Quality as: “Fitness for Purpose.” Quality Guru Philip Crosby defined Quality as: “Conformance to Specifications.”© Oxford University Press 2008. All rightsreserved.
  • 4. 4 „fitness for the purpose‟ means the expectation or requirement of the customer. In all subsequent stages such as development, engineering, production , distribution, and after sales service, quality is measured in terms of „conformance to specifications‟.© Oxford University Press 2008. All rightsreserved.
  • 5.  According to Garvin(1984,1988), quality should have different meanings in different context as 5 follows.  Transcendent or innate excellence.  Product –based or the quantity of a desirable attribute which is present.  User-based in the context of fitness for use.  Manufacturing –based or conformance to specification  Value-based or satisfaction relative to price.© Oxford University Press 2008. All rightsreserved.
  • 6. Definitions 6 Quality Control is defined as maintaining of requisite standards in products or services. ISO 8402 defines Quality Control as: “The operational techniques and activities that are used to fulfill requirements for Quality.” ISO 8402 defines Quality Assurance as:“All those planned and systematic actions necessary to provide adequate confidence that a product or service will satisfy given requirements for Quality.”© Oxford University Press 2008. All rightsreserved.

  • 11.  Various techniques such as quality function deployment, acceptance sampling, statistical 11 process control(SPC), Taguchi methods, and service quality management have to be used to control quality in every sphere of organizational activity.  Total Quality Management (TQM) principles is thee reason why Japanese co‟s became world leaders in quality products.  Six Sigma is the quality philosophy to ensure a reduction of the numbers of the defective products to Zero.© Oxford University Press 2008. All rightsreserved.
  • 12.  It is requirement of ISO 9000 that an org. seeking ISO certification has to conduct internal quality audit on a regular basis 12which is called as first party audit and can be conducted by the trained employees of ISO. Second –party audit may be conducted by an institutional customer of the org to ensure quality standard mentioned in their contract . Two new international quality standard are gaining ground. One is Capability Maturity Model (CMM) developed by Carnegie Mellon University, USA, for the software industry, and other is COPC-2000 developed by a consortium of major multinational companies.

Philip B Crosby’s Contribution to TQM Crosby‟s name is perhaps best known in relation to the concepts of „do it right first time‟ and „zero defects‟. Zero defects does not mean that people never make mistake, but company does not start out expecting them to make mistake. His goal is to give all staff the training and the tool of quality improvement , to apply basic percept of prevention management .
  • 44. Four Absolutes of Quality Management 44 1. Quality is defined as conformance to requirements, not as goodness nor elegance. 2. The system for causing quality is prevention, not appraisal. 3. The performance standard must be Zero Defects, not thats close enough. 4. The measurement of quality is the Price of Non-conformance, not indices.© Oxford University Press 2008. All rightsreserved.
  • 45. Crosby‟s 14 Steps to Quality Improvement 45 1. Make it clear that management is committed to quality. 2. Form quality improvement teams with senior representatives from each department. 3.

All rightsreserved.
  • 62. Company-wide-quality control 62  Ishikawa sees the company wide quality control movement as implying that quality does no mean only product but also post sales service and quality of management, the company and the human being. It has following effect.  Product quality is improved and become uniform. Defects are reduced.  Reliability of goods is improved.  Cost is reduced.© Oxford University Press 2008. All rightsreserved.
  • 63.  Quality of production is increased and it becomes possible to make rational production schedules. 63  Wasteful work and rework are reduced.  Technique is established and improved.  Expenses for inspection and testing are reduced.  Contracts between vendor and vendee are rationalized  The sales market is enlarged.  Better relationship are established between departments.© Oxford University Press 2008.

  • 67. Six Sigma SARVESH SONI/FQM/IE1/CH-7
  • 68.  Six Sigma toolkit is composed of the DMAIC process , the Six Sigma training hierarchy, and poka-yoke. The DMAIC process in fact refers to the steps involved in the implementation of Six Sigma project define, measure, analyse , improve and control. Poka-yoke are simple and inexpensive device used in order to ensure that zero defects are produced by the organisation. SARVESH SONI/FQM/IE1/CH-7
  • 69.  The DMAIC process in six sigma is aid by the seven magnificent quality tools-Ishikawa‟s fishbone diagram, flowcharts, checklists, control charts, histogram, pareto chart and scatter diagram SARVESH SONI/FQM/IE1/CH-7
  • 70. Overview of Total Quality Management (TQM) The Six Sigma Toolkit SARVESH SONI/FQM/IE1/CH-7
  • 71. Meaning of Six Sigma Let us assume the for the process of manufacturing pencils the natural tolerance limits that is, (µ±3s), as given in next figure. Thus, 99.73% of the pencil will have their diameter within the specification limits, while the remaining 0.27% or 27 per 100 or 270000 per million pencils will be defective. The standard deviation of the population is „s‟. SARVESH SONI/FQM/IE1/CH-7
  • 72.  Therefore it gives training to every employee regarding statistical techniques to measure every critical factor responsible for variation. Then , steps are taken to improve the process and reduce variation in the process. For example, workers are trained to reduce the mistakes on their parts, processes are redesigned for better performance, and maintenance of machine is improved. SARVESH SONI/FQM/IE1/CH-7
  • 73.  Note that in below figure , there are 6 standard deviation between the CL and USL or LSL. The value(µ±6s) are now at the specification limits. Now out of every 1 million pencils produced , only 0.002 pencils. This is Six Sigma quality level, meaning zero defective per million opportunities. (DPMO). SARVESH SONI/FQM/IE1/CH-7
  • 74. Meaning of Six Sigma SARVESH SONI/FQM/IE1/CH-7
  • 75. Sigma/ Quality Level viz. Off- Centering SARVESH SONI/FQM/IE1/CH-7
  • 76. Steps in Implementing Six Sigma Step 1 – Define: Define the priorities of the customers with respect to quality  Those attributes of the product are identified that are considered most important by the customers in evaluation the quality off the product. These attributes are called critical to quality characteristics. (CTQ).  The customers perception about the quality attributes are updated from time to time by conducting customer surveys. SARVESH SONI/FQM/IE1/CH-7
  • 77.  Step 2 – Measure : Measure the processes and the defects arising in the product due to the process - The important processes influencing the CTQs are identified and performance measurement techniques are established for these processes. SARVESH SONI/FQM/IE1/CH-7
  • 78.  Step 3 – Analyze: Analyze the process to determine the most likely causes of defects  The key variables most likely to be responsible for variation in the process are identified to find the reason for generation of defects. SARVESH SONI/FQM/IE1/CH-7
  • 79.  Step 4 – Improve : Improve the performance of the process and remove the causes of the defects  The specification limits of the key variable are fixed and the system established for measuring the deviation of the variable is validated.  Improvisation in the process are done in order to keep the variable within the specification limits. SARVESH SONI/FQM/IE1/CH-7
  • 80.  Step 5 – Control : Ensure that the improvements are maintained over time  The modified process is subjected to vigil at regular intervals of times to ensure that the key variables do not show any unacceptable variation (beyond the specification limits)  There are certain situation where the project team members may feel that a process needs to be replaced by a new process rather than improving the exiting process.  The demand of the customer with regard to quality cannot satisfied by the existing process. SARVESH SONI/FQM/IE1/CH-7
  • 81.  At times , an organization may decide to launch a new product or service to grab a new business opportunity offered by the environment. In all such situation last two steps in the DMAIC, namely, „improve‟, „ control‟ have to be replaced by „design‟ and „verify‟ so that it becomes DMADV. SARVESH SONI/FQM/IE1/CH-7
  • 82. Final and First-Pass Yield SARVESH SONI/FQM/IE1/CH-7
  • 83. Cost of Poor Quality (COPQ)COPQ will generally include the following cost components:1) Cost of labor to fix the problem.2) Cost of extra material used.3) Cost of extra utilities4) Cost of lost opportunity a) Loss of sales/revenue (profit margin) b) Potential loss of market share c) Lower service level to customers SARVESH SONI/FQM/IE1/CH-7

  • 88. The Seven Magnificent Quality Tools1. Ishikawa‟s fish bone diagram2. Flowcharts3. Checklists4. Pareto charts5. Histogram6. Scatter diagrams7. Control Charts SARVESH SONI/FQM/IE1/CH-7
  • 89. 1. Ishikawa‟s fish bone diagram Japanese quality GURU Kaoru Ishikawa is the inventor of the diagram. It is used to represent the various causes of an effect, a problem, or quality characteristics. This is useful to find out the root cause of a problem. SARVESH SONI/FQM/IE1/CH-7
  • 90.  There are two sets of general categories of main causes used in the fish bone diagrams. 3Ms and 1p, that is Methods, Machinery, Material, People. 4Ps that is, Policies, Procedures, People, and Plant.  For each main cause , various sub-causes are identified and represented . SARVESH SONI/FQM/IE1/CH-7
  • 91. Ishikawa‟s Fish Bone Diagram SARVESH SONI/FQM/IE1/CH-7
  • 92. Pareto chart Pareto Charts have been named after Alfred Pareto (1848-1923). It is based upon 80:20 principle. It means 80% of the quality problem caused by 20% of the causes. In the preparation of this charts, various causes resulting in quality problem are identified and arranged in the descending order of the magnitude of defects they produce SARVESH SONI/FQM/IE1/CH-7
  • 93. Histogram This tool is often used during the „analyze‟ phase of the DMAIC process. This shows the before and after situation of implementing quality improvement measures. SARVESH SONI/FQM/IE1/CH-7
  • 94. Scatter Diagram It used to find out relationship between a cause and effect. Ishikawa‟s Fishbone helps to find thee root cause of an effect while scatter diagram help to identify the kind and level of relationship. For ex….. SARVESH SONI/FQM/IE1/CH-7
  • 95. Poka-Yoke The Japanese word Poka-Yoke has been derived from Yokeru (to avoid) Poka (inadvertent errors). Shigeo Shingo propounded the concept of “Zero Quality Control” using Poka-Yoke devices leading to “Defects = Zero”. This concept is synonymous with terms like “Fail-safing”, “Fail- proofing”, “Fool-proofing”, “Error-proofing” and “100% inspection”. SARVESH SONI/FQM/IE1/CH-7
  • 96. Three Major Inspection Methods1. Judgment Inspection - This is the inspection of finished products so that the defective products can be separated from good ones before deliveries are made to the customer.2. Informative inspection - here, the root cause of defects are investigated and this information is passed to the relevant processes for corrective action.3. Source inspection SARVESH SONI/FQM/IE1/CH-7
  • 97. Zero Quality Control (ZQC)1. Source Inspection: In this form of inspection, factors causing defects are inspected rather than the resulting defects. If 100% inspection is adapted at the source, the mistake can be avoided completely before it becomes a defect.2. Immediate action: Whenever a mistake is detected, operations are stopped immediately and resumed only upon corrective action. SARVESH SONI/FQM/IE1/CH-7
  • 98. Quality Function Deployment SARVESH SONI/FQM/IE1/CH-7
  • 99. Origin of QFD Quality Function Deployment (QFD) has its origins at Bridgestone Tire Kurume plant, where the Quality Chart was used for the first time in 1966. In 1972, Mitsubishi applied the QFD technique developed to its present form by Dr. Yogi Akao, a professor at Asahi SARVESH SONI/FQM/IE1/CH-7
  • 100. QFD Defined The American Society for Quality Control defines quality function deployment as a "structured method in which customer requirements are translated into appropriate technical requirements for each stage of product development and production. The QFD process is often referred to as listening to the voice of the customer" (Bemowski, 1992). SARVESH SONI/FQM/IE1/CH-7
  • 101.  QFD is a method that determines customer requirements, deploys quality improvement resources to meet those requirements, and measure customer satisfaction to determine success. QFD is not only suitable for designing products but for services as well. The word „function‟ in QFD refers to a function analysis of the business process phases in order to improve the quality of the product development process itself SARVESH SONI/FQM/IE1/CH-7
  • 102. Application of QFD (By Japanese Society of Quality Control) Seting design quality and planned quality Benchmarking competitive products New produt development that sets the company apart from competitors Analyzing and accumulating market quality information Communicating quality –related information to later proceess SARVESH SONI/FQM/IE1/CH-7
  • 103.  Deploying design intent into manufacturing Identifying control points for the gemba(a Japanese word that refers to the place where source information can be learned) SARVESH SONI/FQM/IE1/CH-7

  • 106.  STEP A: Conduct marketing research to determine the „VOCs‟ i.e. customer‟s preference and then, place the voices in part A of the house of Quality. By- Focus group, Personal-Telephonic Interview, mail questionnaire. SARVESH SONI/FQM/IE1/CH-7
  • 107. Kano‟s Model It is possible the some of the root need of the customer may not get revealed. Kano(1984) diagram useful to characterized customer needs, which can help us gain profound understanding of customer satisfaction. The X-axis represent the performance of the product and Y-axis represent the level of satisfaction attained by the customer. Each product feature affects customer satisfaction in a different way. SARVESH SONI/FQM/IE1/CH-7
  • 108. Kano‟s Model SARVESH SONI/FQM/IE1/CH-7
  • 109.  Must be attribute(basic Quality): Customer take these for granted when fulfilled. However, if the product does not meet this basic need sufficiently, the customer may become very dissatisfied. One dimensional attribute (expected quality): These attributes result in customer satisfaction when fulfilled and dissatisfaction when not fulfilled in equal proportion with respect to the performance of the product. The better these attributes are the more customer likes the product SARVESH SONI/FQM/IE1/CH-7
