D.A. Garvin (1987) mentioned the eight dimensionsof quality. What are the main difference incomparison to other definitions about quality? Givea short description.

David A. Garvin's eight dimensions of quality, proposed in 1987, provide a more detailed understanding of the concept of quality compared to other definitions. These dimensions include performance, features, reliability, conformance, durability, serviceability, aesthetics, and perceived quality.

1. Performance: This refers to a product's primary operating characteristics. For example, a car's acceleration speed.
2. Features: These are additional characteristics that enhance the appeal of the product. For example, a car might have an advanced entertainment system.
3. Reliability: This refers to the probability of a product malfunctioning or failing within a specified period.
4. Conformance: This is the degree to which a product's design and operating characteristics meet established standards.
5. Durability: This is a measure of product life, both in terms of technical life (how long the product lasts before it deteriorates) and repair life (how long the product can be used before it can no longer be economically repaired).
6. Serviceability: This is the speed, courtesy, competence, and ease of repair.
7. Aesthetics: This is how a product looks, feels, sounds, tastes, or smells. It's largely a matter of personal judgment and a reflection of individual preference.
8. Perceived Quality: This is influenced by brand name, advertising, and other intangible aspects.

The main difference between Garvin's dimensions and other definitions of quality is that Garvin's approach is more comprehensive. It doesn't just focus on the functionality of the product (as in the case of the traditional definition of quality), but also considers other factors that might influence a customer's perception of quality. This makes it a more customer-centric approach to defining quality.
