Modern Importance of QualityModern Importance of Quality
“The first job we have is to turn out quality merchandise that consumers will buy and keep on buying. If we produce it efficiently and economically, we will earn a profit, in which you will share.”
- William Cooper Procter

Quality Assurance
Quality Assurance refers to the process used to create the appropriate deliverables, and can be performed by a manager, client, or even a third-party reviewer.
Examples of quality assurance include process checklists, visual aids, and project audits, mistake proofing, etc.
5
Quality Control• Quality Control refers to quality related
activities associated with the project deliverables • Quality control is used to verify that
deliverables are of acceptable quality and that they are complete and correct.
• Examples of quality control activities include inspection, audit and the testing process.
6
Qualitative vs. Subjective
• Qualitative quality can be measured, and compared using values that are specific, black and white
• Subjective quality cannot be measured, and comparisons are intuitive, gut level, hard to define

Deming’s System of Profound Knowledge
• Appreciation for a system• Understanding variation• Theory of knowledge• Psychology
16
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
17
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
18
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
19
Psychology
• People are motivated intrinsically and extrinsically
• Fear is demotivating • Managers should develop pride and joy
in work
20

Phillip B. Crosby
Quality is free . . . :“Quality is free. It’s not a gift, but it is free. What costs money are the un-quality things -- all the actions that involve not doing jobs right the first time.”
25
Philip B. Crosby
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

Workshop
What is Quality
41
Quality is Not!
• 100% inspection• Management fad• Statistical Process Control• Employee involvement• Another excuse for a “management retreat”• Only applies to manufacturing
42
Quality is…
• A philosophic way of thinking
• All things can be looked at from a quality perspective
• Manufacturing• Managing• Driving• Using• Living• Etc., etc., etc.
43
Dimensions of Quality
• Definitions of Quality Quality means fitness for use
- quality of design
- quality of conformance
Quality is inversely proportional to variability.
44
Dimensions of Quality
• Quality Improvement
Quality improvement is the reduction of variability in processes and products.
Alternatively, quality improvement is also seen as “waste reduction”.
45
Dimensions of Quality – Transmission Example
46
Quality Terminology
Quality Characteristics
• Physical - length, weight, voltage, viscosity• Sensory - taste, appearance, color• Time Orientation - reliability, durability,
serviceability
47
Quality Terminology
Quality engineering is the set of operational, managerial, and engineering activities that a company uses to ensure that the quality characteristics of a product are at the nominal or required levels.
48
Quality Terminology
Two types of data
• Attributes Data - discrete data, often in the form of counts.
• Variables Data - continuous measurements such as length, weight.
49
Quality Terminology
Specifications Quality characteristics being measured are
often compared to standards or specifications.
• Nominal or target value• Upper Specification Limit (USL)• Lower Specification Limit (LSL)
50
Quality Terminology
• When a component or product does not meet specifications, they are considered to be nonconforming.
• A nonconforming product is considered defective if it has one or more defects.
• Defects are nonconformities that may seriously affect the safe or effective use of the product.
51
Quality Terminology
• Concurrent Engineering
Team approach to design. Specialists from manufacturing, quality engineering, management, etc. work together for product or process improvement.
52
Definitions of QualityDefinitions of Quality
• Transcendent definition: excellence• Product-based definition: quantities of
product attributes• User-based definition: fitness for intended
use• Value-based definition: quality vs. price• Manufacturing-based definition:
conformance to specifications

The Costs of Quality
77
Workshop
Cost
78
The Cost of Quality (COQ)
• COQ – the cost of avoiding poor quality, or incurred as a result of poor quality
• Translates defects, errors, etc. into the “language of management” – $$$
• Provides a basis for identifying improvement opportunities and success of improvement programs
79
Quality Cost Classification
• Prevention• Appraisal• Internal failure• External failure
80
Quality Cost Management Tools
• Cost indexes• Pareto analysis• Sampling and work measurement• Activity-based costing
81
Return on Quality (ROQ) • ROQ – measure of revenue gains against
costs associated with quality efforts• Principles
• Quality is an investment
• Quality efforts must be made financially accountable
• It is possible to spend too much on quality
• Not all quality expenditures are equally valid
82
Managing Data and Information
• Validity – Does the indicator measure what it says it does?
• Reliability – How well does an indicator consistently measure the “true value” of the characteristic?
• Accessibility – Do the right people have access to the data?
83
Analysis• Statistical summaries and charts• Trends over time• Comparisons with key benchmarks• Aggregate summaries and indexes• Cause-and-effect linkages and
correlations (interlinking)• Data mining

Communication
86
Workshop
Listening
87
Listening
• The most difficult thing to do
• We have not been taught to listen
• We have a preset bias
• We drift to things that have happened to us
• We apply our experiences to another
88
• Vertical communication• Horizontal communication• Multi-communicaation
89
Barriers to communication
• Differences in perception • Differences in listening ability• Differences in interpretation of words/symbols• Differences in status• Personal bias due to race, sex or nationality• Psychological climate or communication environment• Lack of clarity• Lack of definite communication plans• Language or reading barriers
90
Huddles
• Conduct day-to-day communications and business
• Make a decision• Correct a problem or problems• Assign duties• Confer and make an adjustment

• The Golden Goose
95
When is there too much Quality
• The cost of quality erodes the profit• The quality is too far exceeding customer
expectations• Rational turns to Irrational
96
Risk Analysis• 1. Define the problem or issue for the group• 2. Evaluate the issue’s importance in light of time, other team priorities
and the deadline for making the decision• 3. Collect data• 4. Analyze the data• 5. Generate ideas for solutions to the issue• 6. Select a mutually agreeable option for a decision or solution to the
issue• 7. Develop and agree on an action plan, including the assignment of
team member responsibilities for implementing the team’s decision or solution
• 8. New teams pass on the decision and action plan to the Leadership Team
• 9. Implement the action plan• 10. Evaluate the outcome• 11. If the results are negative, return to original scenario and revisit step
6.
97
Balancing the Customer and Company
• Setting up a Review Board• When a Board should be used• Decision making
• Rules of decision making
98
Review Boards
• Present each areas perspectives on the problem
• Allow each to weigh the severity and repercussion of decision
• See if there is a resolution that will ensure the problem will never happen again.
• Determine if the resolution has value
99
Meeting Customers Expectation
100
Workshop
Who is the Customer?
101
Importance of Customer Satisfaction and Loyalty
• “Satisfaction is an attitude; loyalty is a behavior”• Loyal customers spend more, are willing to pay
higher prices, refer new clients, and are less costly to do business with.
• It costs five times more to find a new customer than to keep an existing one happy.
102
American Customer Satisfaction Index
• Measures customer satisfaction at national level• Introduced in 1994 by University of Michigan
and American Society for Quality• Continual decline in index from 1994 through
1998 with a small improvement into 2000 suggests that quality improvements have not kept pace with consumer expectations

107
Key Customer Groups
• Organization level• consumers• external customers• employees • society
• Process level• internal customer units or groups
• Performer level• individual internal customers
108
Identifying Internal Customers• What products or services are produced?• Who uses these products and services?• Who do employees call, write to, or answer
questions for?• Who supplies inputs to the process?

Two Fundamental Management Mistakes
1. Treating as a special cause any fault, complaint, mistake, breakdown, accident or shortage when it actually is due to common causes
2. Attributing to common causes any fault, complaint, mistake, breakdown, accident or shortage when it actually is due to a special cause
122
Creative Problem Solving
• Mess Finding – identify symptoms• Fact Finding – gather data; operational
definitions• Problem Finding – find the root cause• Idea Finding – brainstorming • Solution Finding – evaluate ideas and
proposals• Implementation – make the solution work
