Foundations of quality management
Quality Improvement
the process of breaking through to unprecedented levels of performance
Quality planning
the process of preparing to meet quality goals
Deming Chain Reaction
1. Improve Quality 2. Costs decrease because of less rework, fewer mistakes, fewer delays and snags, and better use of time and materials 3. Productivity improves 4. Capture the market with better quality and lower price 5. Stay in business 6. Provide jobs and more jobs
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." Zero defects

What is quality related to?
1. Product performance 2.freedom from project deficiencies
Breakthrough Sequence
1. Proof of need 2. Project Identification 3. Organization of the breakthrough 4. Diagnostic Journey 5. Holding the gains
A.V. Feigenbaum
1. Quality Leadership- Maintain constant focus and lead quality effort 2.Modern quality technology- Integrated approach. All workers at every level must continue to evaluate and implement new techniques 3. organizational commitment - continuous training and motivation
Variation and statistical thinking
1. all work occurs in a system of interconnected processes 2. variation exists at all processes 3.understanding and reducing variation
ISO 9000:2000
A set of quality standards created by the International Organization for Standardization and revised in 2000 highlights all quality principles
Absolutes of Quality Management
Crosby 14 point system four principles 1.Quality is achieved through conformance standards. 2.Quality through prevention of defects is better and more cost effective- then quality through inspection. 3. Zero defects is the quality performance standard. It is possible when higher performance standards are implemented. 4. Quality is measured by the price of nonconformance; costs to increase quality should be assumed in organizations finance. No such thing as Economics of quality, do it right the first time
Deming's Red Bead Experiment
Box has red and white beads (80% of beads are white, 20% of beads are red) Customer will only accept white beads Worker scoops 50 beads with a paddle Inspector counts and records # of acceptable beads Management reacts at the end of each day
Kaoru Ishikawa
Cause-and-effect diagram Quality circles Recognized the internal customer developed "fishbone diagram" Quality begins with the customer
Theory of Knowledge
Concerned with the nature and scope of knowledge, its bases, and general reliability of claims to knowledge knowledge isn't possible without theory and understanding statistical models (regression)
Quality Management principles
Customer focus, leadership, involvement of people, process approach, system approach, continuous improvement, factual approach to decision making, mutually beneficial supplier relationships
understand variation
Example:airline on time arrivals
Types of variation
Natural variation (due to common causes) Natural part of the process Special (assignable) causes of variation Use of control charts to identify variation
Appreciation for a system
Parts of a system must work together
Quality Management techniques
Plan work activities, Collect data, analyze results, monitor progress, statistics, and solve problems
Juran Philosophy
Quality trilogy: 1. Quality planning 2.Quality control 3.Quality improvement
System
Set of functions or activities within an organization
Deming Philosophy
The 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.
Quality Control
The process of meeting quality goals during operations
System of Profound Knowledge
This outlines Dr. W. Edwards Deming's philosophy based on the view that all elements of an organization should work in concert together as an interdependent system. The four elements lay out a framework for managers to reduce costs while increasing quality, customer loyalty, worker satisfaction and, ultimately, profitability. 1. Appreciation for a System 2. Knowledge of Variation 3. Theory of Knowledge 4. Psychology of Change
Res bead experiment lessons
Variation exists in systems Variation in colors, and from day to day, came entirely from the process Numerical goals are often meaningless Management is responsible for the system
Problem 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

14 Points (concept)
represented radical departure from management and thinking practice 60's and 70's manufacturing was driven by quotas believed companies could not prosper with this type of management
