What is Quality? • Descriptors for quality ? • Performance • Aesthetics • Special Features • Safety • Reliability • Durability • Perceived Quality • Service After Sale • What does it mean to you as a producer?, as a consumer? • Quality can be more than improving cost and throughput.
Definition of Quality • Quality as Excellence • Relative to a standard such as a competitor • Level of quality can be ever changing • Quality as Conformance to Specification • Emphasis is on manufacturing quality • Number of defects relative to design • Does not guarantee it meets customer needs • Quality as Fitness for Use • Includes engineering and marketing in the quality equation • High quality is when the product meets the customers expressed and • intended needs • Quality as Value for the Price • Level of quality is relative not only to similar products but to substitutes • Part of strategic quality plan
Determinants of Quality • How do we determine quality? • Design • How well it conforms to the design • Ease of use • Service after delivery • Does it do what I expect it to do. • Does it do it when I want it to. • Is it available when I want it. • Is it at the right price. What are the advantages of quality?
Cost of Quality • Can you quantify how much the lack of quality is costing you? • Do you know which operations have the highest cost due to lack of • quality? • Internal and external • How do you measure the costs of quality? • Number of defects • $ spent to fix rework and scrap • $ lost due to missed due dates • COQ can provide justification for improvement initiatives. • Time and money are limited so need to apply where it does the most • good • True costs are typically hard to capture.
Quality Metrics • Product • Reliability: Mean Time Between Failure • Durability: under what conditions is the product design to operate • Serviceability:Can it be repaired, at what cost, where can it be repaired • Service • Reliability: Can the work be performed correctly • Tangibles: What impression does the customer have. • Responsiveness: Prompt service • Assurance: Does the customer feel you know what you are doing • Empathy: The customer is not a number
Symbols of Quality • ISO 9000 quality standard • Documentation of quality procedures and on-site assessment • Everyone is working to a process • Corrective and preventive actions • ISO 14000 • Assess a company’s performance in terms of environmental • responsibility • Management systems, Operations, Environmental systems measures • The Deming Prize: focus on statistical quality control • Malcolm Baldridge National Quality Award • Provides a means to assess a firms individual performance • Compare their organization with others • Focus on customer satisfaction
Quality in Historical Perspective • Inspection • Sampling • 100% inspection • What are some of the Pros and Cons? • Statistical Process Control • Looking for Trends • X charts, R charts, C charts • Operator evaluation • Quality Assurance • Quality is the responsibility of everyone ( not just the Quality group) • Everyone is to look for changes within their work. • Strategic Quality Management’ • Previous methods looked at quality as reducing costs. • Recognizes the competitive advantage of quality
Quality Management Leadership • W.

Juran • Focused on Total Quality Control • Based on: Quality Planning, Quality Control, Quality Improvement • Philip Crosby • Four Absolutes of Quality Management • What is quality ? • What system do we need to institute so that we offer a quality product or service. • Which performance standard should we use to measure the quality of • our performance? • Which system is appropriate for measuring the quality of what we do?
Total Quality Management • Def: An organizational approach to total customer satisfaction and a continuous process of improvement. • TQM is: • A philosophy and a set of quiding principles and tasks for improving • quality • A way to manage an organization based on “Total Customer” satisfaction • and a continuous process of improvement • The way we would do things if we had not thought of a worse way. • TQM Includes: • 1.

Effective design of products and services. • Requires that quality go beyond manufacturing • Intended use • Customer needs • Design for Manufacturing • 6. Effective Leadership • Quality has to be a top down process • Otherwise it is a Fad. • Read TQM Implementation Process (P 280-281)
Barriers to TQM • 1. Assuming that implementing total quality will quickly and completely end all the • organizations ills. • 2.

Becoming so obsessive about internal quality activities that critical performance • issues, such as financial performance and external customers needs are • overlooked. • 5. Creating hundreds of improvement teams and failing to provide resources, • direction, training , and encouragement to help ensure success. • 6. Adopting an off-the-shelf quality program without modifying it to match the • company’s unique characteristics. • 7. Failing to link quality goals to financial returns and compensation.
