4 dimensions of quality

To learn more about grouping measures into categories, go to Organizing Measures To Reduce Information Overload. The quality of product or service design is determined by the features that are included in the final design of the product or service. But managers have to take a more preliminary step—a crucial one, however obvious it may appear. A final word, not about strategic opportunities, but about the worst strategic mistakes. Because these measures require a product to be in use for a specified period, they are more relevant to durable goods than to products and services that are consumed instantly. 5. After extensive research, Zeithaml, Parasuraman and Berry found five dimensions customers use when evaluating service quality. At incoming inspection, the Japanese chips had a failure rate of zero; the comparable rate for the three U.S. manufacturers was between 11 and 19 failures per 1,000. Thus, separating the effects of a particular factor from other factors may be difficult. The quality of an automobile tire may reflect its tread-wear rate, handling, traction in dangerous driving conditions, rolling resistance (i.e., impact on gas mileage), noise levels, resistance to punctures, or appearance. There are other trade-offs. What are its core competencies and how will you leverage them? Formal techniques for problem solving, however, remained limited. Others disputed the basic data. Still, durability varies widely among brands. Overall performance rankings, however, are more difficult to develop, especially when they involve benefits that not every consumer needs. P. Greg Bonner and Richard Nelson, “Product Attributes and Perceived Quality: Foods,” in Perceived Quality, ed. Consumer Network, Inc., Brand Quality Perceptions (Philadelphia: Consumer Network, August 1983), p. 17 ad 50–51. Because this dimension of quality involves measurable attributes, brands can usually be ranked objectively on individual aspects of performance. A product’s durability, for example, can seldom be observed directly; it usually must be inferred from various tangible and intangible aspects of the product. Crossing the Quality Chasm: A New Health System for the 21st Century. The quality of conformance to design is the result of how well the product or service meets its specifications. Even the quality of a less tangible product like computer software can be evaluated in multiple dimensions. The American Academy of Family Physicians promotes a biopsychosocial model of healthcare that embodies the spirit of the WHO’s definition. U.S. managers know that they have to improve the quality of their products because, alas, U.S. consumers have told them so. For computer users that find down-time intolerable, like telephone companies and utilities, Tandem has devised a fail-safe system: two processors working in parallel and linked by software that shifts responsibility between the two if an important component or subsystem fails. It is one thing to do a quality job, but it is quite another to unearth any defects lurking in the work product and ensure that a good-quality product is indeed built. One drawback of this approach is the problem of “tolerance stack-up”: when two or more parts are to be fit together, the size of their tolerances often determines how well they will match. These dimensions, once defined, can be applied to help analyze data quality and formulate quality data policy. They named their survey instrument SERVQUAL. The most fundamental definition of a quality. These are still hard questions today. https://www.ahrq.gov/talkingquality/measures/six-domains.html. Technically, durability can be defined as the amount of use one gets from a product before it deteriorates. A subsequent study by the Rand Corporation estimated that every vacuum tube the military used had to be backed by nine others in warehouses or on order. Companies would never make high-quality products, he argued, if the manufacturing department were forced to pursue quality in isolation. 6/6/2006 15 Consequently, the combining of similar variables into dimensions avoids this measurement problem. This dimension reflects the probability of a product malfunctioning or failing within a specified time period. Farmers, for example, are especially sensitive to downtime during the short harvest season. These specifications are normally expressed as a target or “center”; deviance from the center is permitted within a specified range. Exhibit Two approaches to conformance Source: L.P. Sullivan, “Reducing Variability: A New Approach to Quality,” Quality Progress, July 1984, p. 16. Some do their best to resolve complaints; others use legal gimmicks, the silent treatment, and similar ploys to rebuff dissatisfied customers. In order to develop a more complete definition of quality, we must consider some of the key dimensions of a quality product or service. The first is direct confrontation with an industry’s leader. Durability, then, may be defined as the amount of use one gets from a product before it breaks down and replacement is preferable to continued repair.
