  1. Definition:Total Quality Management • Total Quality Management (TQ, QM or TQM) and Six Sigma (6) are sweeping “culture change” efforts to position a company for greater customer satisfaction, profitability and competitiveness. • TQM may be defined as managing the entire organization so that it excels on all dimensions of products and services that are important to the customer.

  2. Quality Descriptions Design Quality (Features) vs. Conformance Quality

  3. Conformance Quality • Meeting Our Customer’s Requirements • Doing (the Right) Things Right the First Time; Freedom from Failure (Defects) • Consistency (Reduction in Variation) • Continuous Improvement • Quality in Everything We Do

  4. Quality Management History • Frederick Winslow Taylor wrote Principles of Scientific Management in 1911 • Walter A. Shewhart used statistics in quality control and inspection, and showed that productivity improves when variation is reduced (1924); wrote Economic Control of Manufactured Product in 1931 • W. Edwards Deming and Joseph M. Juran, students of Shewhart, went to Japan in 1950; began transformation from “shoddy” to “world class” goods • In 1960, Dr. K. Ishikawa formalized “quality circles” - the use of small groups to eliminate variation and improve processes • In the late ‘70’s and early 80’s: - Deming returned from Japan to write Out of the Crisis, and began his famous 4-day seminars in the United States - Phil Crosby wrote Quality is Free - NBC ran “If Japan can do it, why can’t we?” - Motorola began 6 Sigma

  5. Quality Management History “On the assembly line at the Ford Motor Company in 1923, most of the workers producing Model T’s were immigrants and could not speak English. Many were also illiterate. Workers learned their trade by modeling the actions of other workers. They were unable to plan, problem-solve, and make decisions. As a result, the Taylor scientific school of management flourished, and MBAs and industrial engineers were invented to do this work. Today, however, the workforce is educated. Workers know what is needed to improve their jobs, and companies that do not tap into this significant source of knowledge will truly be at a competitive disadvantage.” Joseph M. Juran (1991)

  6. Quality Management History “Knowledge-worker productivity is the biggest of the 21st-century management challenges. In the developed countries, it is their first survival requirement. In no other way can the developed countries hope to maintain themselves, let alone to maintain their leadership and their standards of living.” Peter F. Drucker (1999)

  7. Quality Management History Deming’s 14 Points 1. Create constancy of purpose for improvement 2. Adopt a new philosophy 3. Cease dependence on mass inspection 4. Do not award business on price alone 5. Work continually on the system of production and service 6. Institute Modern methods of training 7. Institute modern methods of supervision of workers 8. Drive out fear 9. Break down barriers between departments 10. Eliminate slogans, exhortations, and targets for the work force 11. Eliminate numerical quotas 12. Remove barriers preventing pride of workmanship 13. Institute a vigorous program of education and retraining 14. Take action to accomplish the transformation

  8. A Quality Management System Is… • A belief in the employee’s ability to solve problems • A belief that people doing the work are best able to improve it • A belief that everyone is responsible for quality

  9. Quality Management History Deming’s Concept of “Profound Knowledge” • Understanding (and appreciation) of Systems - optimizing sub-systems sub-optimizes the total system - the majority of defects come from systems, the responsibility of management (e.g., machines not in good order, defective material) • Knowledge of Statistics (variation, capability, uncertainty in data, etc.) - to identify where problems are, and point managers and workers toward solutions • Knowledge of Psychology (Motivation) - people are afraid of failing and not being recognized, so they fear how data will be used against them • Theory of Knowledge - understanding that management in any form is a prediction, and is based on assumptions

  10. Elements for Success • Management Support/Involvement • Mission Statement • Proper Planning • Customer and Bottom Line Focus • Measurement • Empowerment/Shared Leadership • Teamwork/Effective Meetings • Continuous Process Improvement • Dedicated Resources/Training

  11. Benchmarking 1. Identify those processes needing improvement. 2. Identify a firm that is the world leader in performing the process (Library & WWW). 3. Contact the managers of that company and make a personal visit to interview managers and workers. 4. Analyze data

  12. Organizational Profile: Environment, Relationships, and Challenges 2 Strategic Planning 5 Human Resource Development & Management 1 Leadership 7 Business Results 3 Customer and Market Focus 6 Process Management Baldrige Award Criteria Framework Information, Analysis, and Knowledge Management

  13. Malcolm Baldrige NationalQuality Award (2004) 1.0 Leadership (120 points) 2.0 Strategic Planning (85 points) 3.0 Customer and Market Focus (85 points) 4.0 Information and Analysis (90 points) 5.0 Human Resource Focus (85 Points) 6.0 Process Management (85 points) 7.0 Business Results (450 points)

  14. Categories for the Baldrige Award • Manufacturing companies or subsidiaries that: • produce and sell manufactured products or manufacturing processes or • produce agricultural, mining, or construction products. • Service companies or subsidiaries that sell service • Small businesses • Education Institutions • Health Care Organizations • Non-Profit (new)

  15. Characteristics of a Baldrige Award Winner • The companies formulated a vision of quality and how they would achieve it. • Senior management was actively involved. • Companies carefully planned and organized their quality effort to insure effective initiation. • They vigorously controlled the overall process. • Studies have shown MBA Winners’ success.

  16. ISO 9000 • Series of standards agreed upon by the International Organization for Standardization(ISO) • Adopted in 1987 • More than 100 countries • A prerequisite for global competition? • ISO 9000 directs you to: • document what you do and then do as you documented.

  17. ISO 9000 Series • 9001 • Model for Quality Assurance in Design, Production Installation, and Servicing. • 9002 • Model for Quality Assurance in Production and Installation • 9003 • Model for Quality Assurance in Final Inspection Test

  18. Three Forms of Certification 1. First party: A firm audits itself against ISO 9000 standards. 2. Second party: A customer audits its supplier. 3. Third party: A "qualified" national or international standards or certifying agency serves as auditor.

  19. ISO 9000 versus the Baldrige Award • Which should we pursue first? • What are the differences between the two? • Do you have to be ISO 9000 certified before going for the Baldrige Award?

  21. Costs of Quality: Categories • Appraisal costs • Prevention costs • Internal failure costs • External failure costs

  22. The 1-10-100 Rule 1 10 100 · Defects caught at their source cost the organization $1. · Defects caught outside of the source department but within the organization cost $10. · Defects that reach the external customer cost $100!

  23. Cost of Poor Quality Category Examples Failure – Costs – InternalPrevention Costs Re-shipping Quality Administration Unnecessary Travel Time Quality Planning Re-picking/Picking Quality Systems Design Unpacking/Storing Returns Calibration and Maintenance Re-order Time Production/Inspection Equipment Crediting Time Vendor Assessment Quality Training Failure Costs – ExternalAppraisal Costs Loss of Sales Incoming Test and Inspection Complaints In-Process Inspection Returns Final Inspection Warranty Claims Sampling Procedures Quality Audits

  41. Five Most Common Reasons For Returns From QA January-May (61 units)

  42. Reasons for Returns from QA- Weighted Average Weighted Avg. = % Occurring X Defect Cost (0-10, Based on Time to Repair)

  43. Why Dirt? Environment • Dust/Humidity • Poor Lighting • Space Limitations Measurement • QA Manager Fixes Some Things Without Informing the Technicians Methods • Need to Rinse Parts off after Sandblasting • Need Better Procedure for Determining What to Remanufacture Based on its Condition Machines • Best tools for $$? Materials • Cleaning Compounds watered down • Need Larger Wire Brushes People • Need More Training • More Attention to Detail – Do it Right the First Time

  44. Why Leaks? Environment • High Temperatures in Warehouse • Poor Lighting Materials • Bad Tubing • “O” Rings Out of Spec • “O” Rings Too Old (Dry) Machines • Bad Dispenser Design • Need Rims That Make it Easier to Install Tubing People • Use Wrong Clamps • Don’t Crimp Properly • Forget to Connect Methods • Softening Tubing with Water that’s Too Hot • Need to Check Units for All Possible Ways They Could Leak Measurement • No Testing for Leaks Prior to QA • Need to ID by Mfr./Model Which Units Leak the Most

  45. 1. Plan a change aimed at improvement. 4. Institutionalize the change or abandon or do it again. 4. Act 1. Plan 3. Check 2. Do 3. Study the results; did it work? 2. Execute the change. PDCA Cycle (Deming Wheel)

  46. What is Six Sigma? • A sweeping culture change effort to position a company for greater customer satisfaction, profitability and competitiveness (developed by Motorola in the late 1970’s) • A goal of near perfection in meeting customer requirements • A comprehensive and flexible system for achieving, sustaining and maximizing business success; uniquely driven by close understanding of customer needs, disciplined use of facts, data, and statistical analysis, and diligent attention to managing, improving and reinventing business processes

  47. Six Sigma DMAIC Process Define: Define who your customers are, and what their requirements are for your products and services – Their expectations. Define your team goals, project boundaries, what you will focus on and what you won’t. Define the process you are striving to improve by mapping the process. Control Improve Define Analyze Measure

  48. Six Sigma DMAIC Process Measure: Eliminate guesswork and assumptions about what customers need and expect and how well processes are working. Collect data from many sources to determine speed in responding to customer requests, defect types and how frequently they occur, client feedback on how processes fit their needs, how clients rate us over time, etc. The data collection may suggest Charter revision. Control Improve Define Analyze Measure

  49. Six Sigma DMAIC Process Analyze: Grounded in the context of the customer and competitive environment, analyze is used to organize data and look for process problems and opportunities. This step helps to identify gaps between current and goal performance, prioritize opportunities to improve, identify sources of variation and root causes of problems in the process.
