27. 15–27 Managing Total Quality (cont’d) Eight Dimensions of Quality 1.Performance. A product’s primary operating characteristic. Examples are automobile acceleration and a television’s picture clarity. 2.Features. Supplements to a product’s basic functioning characteristics, such as power windows on a car. 3.Reliability. A probability of not malfunctioning during a specified period. 4.Conformance. The degree to which a product’s design and operating characteristics meet established standards. 5.Durability. A measure of product life. 6.Serviceability. The speed and ease of repair. 7.Aesthetics. How a product looks, feels, tastes, and smells. 8.Perceived quality. As seen by a customer.

28. 15–28 Managing Total Quality (cont’d) Total Quality Management (TQM) –A strategic commitment by top management to change its whole approach to business and to make quality a guiding factor in everything the organization does. Strategic commitment Quality improvements Employee involvement MaterialsMethodsTechnology Figure 15.3

29. 15–29 Managing Total Quality (cont’d) TQM Tools and Techniques –ISO 9000—a set of quality standards created by the International Organization for Standardization by which firms can be certified. –Statistical Quality Control (SQC)—a set of statistical techniques that can be used to monitor quality; includes acceptance sampling and in-process sampling. –Benchmarking The process of learning how and what other firms do in an exceptionally high-quality manner.

30. 15–30 Managing Total Quality (cont’d) TQM Tools and Techniques –Outsourcing Subcontracting operations/services to those who can do them cheaper and/or better. –Speed the time needed by the organization to get something accomplished.

31. 15–31 Guidelines for Increasing the Speed of Operations 1.Start from scratch (it’s usually easier than trying to do what the organization does now faster). 2.Minimize the number of approvals needed to do something (the fewer people who have to approve something, the faster approval will get done). 3.Use work teams as a basis for organization (teamwork and cooperation work better than individual effort and conflict). 4.Develop and adhere to a schedule (a properly designed schedule can greatly increase speed). 5.Don’t ignore distribution (making something faster is only part of the battle). 6.Integrate speed into the organization’s culture (if everyone understands the importance of speed, things will naturally get done quicker).
