OM 456 Lecture 2A Foundations of Quality Management
Deming's 14 Points (Abridged)
1. Create and publish a company mission statement and commit to it. 2. Learn the new philosophy. 3. Understand the purpose of inspection. 4. End business practices driven by price alone. 5. Constantly improve system of production and service. 6. Institute training. 7. Teach and institute leadership. 8. Drive out fear and create trust. 9. Optimize team and individual efforts. 10. Eliminate exhortations for work force. 11. Eliminate numerical quotas and M.B.O. Focus on improvement. 12. Remove barriers that rob people of pride of workmanship. 13. Encourage education and self-improvement. 14. Take action to accomplish the transformation.
Quality Manual
A permanent reference for implementing and maintaining the system. Typical records -inspection reports -test data -audit reports -calibration data
Statistical Thinking
All work occurs in a system of interconnected processes Variation exists in all processes Understanding and reducing variation are the keys to success
Deming's System of Profound Knowledge
Appreciation for a system Understanding variation Theory of knowledge Psychology
Core Quality Management Principles
Customer focus Teamwork Continuous improvement
Objectives of QMS
Higher product conformity and less variation. Fewer defects, waste, rework, and human error. Improved productivity, efficiency, and effectiveness.
Deming Chain Reaction
Improve quality > Costs decrease > productivity improves > increase market share with better quality and lower prices > stay in business > provide jobs and more jobs
Kaoru Ishikawa
Instrumental in developing Japanese quality strategy Influenced participative approaches involving all workers Advocated the use of simple visual tools and statistical techniques
Theory of Knowledge
Knowledge is not possible without theory Experience alone does not establish a theory, it only describes Theory shows cause-and-effect relationships that can be used for prediction
Variation
Many sources of uncontrollable variation exist in any process Excessive variation results in product failures, unhappy customers, and unnecessary costs Statistical methods can be used to identify and quantify variation to help understand it and lead to improvements
Systems
Most organizational processes are cross-functional Parts of a system must work together Every system must have a purpose Management must optimize the system as a whole
Psychology
People are motivated intrinsically and extrinsically; intrinsic motivation is the most powerful Fear is demotivating Managers should develop pride and joy in work

Three Steps to Quality
Quality Leadership, with a strong focus on planning Modern Quality Technology, involving the entire work force Organizational Commitment, supported by continuous training and motivation
Crosby Philosophy
Quality is free . . . ... It's not a gift, but it is free. What costs money are the unquality things -- all the actions that involve not doing jobs right the first time."
Lessons Learned
Quality is made at the top. Rigid procedures are not enough. People are not always the main source of variability. Numerical goals are often meaningless. Inspection is expensive and does not improve quality.
Crosby's Absolutes of Quality Management
Quality means conformance to requirements Problems are functional in nature There is no optimum level of defects Cost of quality is the only useful measurement Zero defects is the only performance standard
Juran's Quality Trilogy
Quality planning Quality control Quality improvement
TQ Techniques
Statistical methods Visual aids for problem solving, such as flowcharts Techniques specific to quality assurance activities, such as control charts, measurement systems analysis, reliability models, and so on.

Three Steps to Quality
Two Fundamental Management Mistakes
Treating as a special cause any fault, complaint, mistake, breakdown, accident or shortage when it actually is due to common causes Attributing to common causes any fault, complaint, mistake, breakdown, accident or shortage when it actually is due to a special cause
Types of Variation
Uncontrollable variation (common causes) are a natural part of a process Special (assignable) causes of variation can be recognized and controlled Failure to understand these differences can increase variation in a system
Problems Created by Variation
Variation increases unpredictability. Variation reduces capacity utilization. Variation contributes to a "bullwhip" effect. Variation makes it difficult to find root causes. Variation makes it difficult to detect potential problems early.
Leaders in the Quality Revolution
W. Edwards Deming Joseph M. Juran Philip B. Crosby Armand V. Feigenbaum Kaoru Ishikawa
Quality Management System (QMS) -
a mechanism for managing and continuously improving core processes to "achieve maximum customer satisfaction at the lowest overall cost to the organization."
Practices -
activities by which principles are implemented
Deming Philosophy
focuses on continual improvements in product and service quality by reducing uncertainty and variability in design, manufacturing, and service processes, driven by the leadership of top management.
Principles -
foundation of the philosophy
Juran Philosophy
proposed a simple definition of quality: "fitness for use." This definition of quality suggests that it should be viewed from both external and internal perspectives; that is, quality is related to: (1) product performance that results in customer satisfaction; (2) freedom from product deficiencies, which avoids customer dissatisfaction.
Techniques -
tools and approaches to make practices effective
