| Well said. The distinction between "measurable objective" vs. "perceptual subjective" is fundamental to understanding quality. To add to the above; From https://en.wikipedia.org/wiki/Software_quality - The transcendental perspective deals with the metaphysical aspect of quality. In this view of quality, it is "something toward which we strive as an ideal, but may never implement completely". It can hardly be defined, but is similar to what a federal judge once commented about obscenity: "I know it when I see it". The user perspective is concerned with the appropriateness of the product for a given context of use. Whereas the transcendental view is ethereal, the user view is more concrete, grounded in the product characteristics that meet user's needs. The manufacturing perspective represents quality as conformance to requirements. This aspect of quality is stressed by standards such as ISO 9001, which defines quality as "the degree to which a set of inherent characteristics fulfills requirements". The product perspective implies that quality can be appreciated by measuring the inherent characteristics of the product. The final perspective of quality is value-based. This perspective recognizes that the different perspectives of quality may have different importance, or value, to various stakeholders. |
