The Declaration of Interdependence doesn't speak directly to quality but implies reliable results and return on investment as the source of quality. In David Garvin's "What Does Product Quality Really Mean?" is a discussion of the five (5) views of quality
- Transcendental - sees quality as something that can be recognized but not defines. This the Christopher Alexander view of quality quality without a name.
- User - sees quality as fitness for purpose.
- Manufacturing - sees quality as conformance to specification.
- Product - sees quality as tied to inherent characteristics of the product.
- Value - sees quality as dependent on the amount the customer is willing to pay for it.
This discussion is important because the DoI uses general principle terminology. Without the specifics of the practice it's difficult to evaluate the effectiveness of the principle. Starting with a view of quality and the other principle terms in any methodology grounds the discussion in what would be called in our domain actionable outcomes. Without these actionable outcomes the discuss rapidly degenerates to philosophical. In the business domain of project management practitioners have a nature adverse to philosophy of project management.
