Concepts:
Quality Dimensions
Quality, as discussed in the Best
Practices: Verify Quality, is not a simple concept to describe. Likewise,
when our focus turns to the discussion of testing to identify quality, there is
no single perspective of what quality is or how its measured. In Rational
Unified Process, we categorize quality using the FURPS+ model
[GRA92]:
- Functionality
- Usability
- Reliability
- Performance
- Supportability
This is the same categorization scheme that we use for requirements, which is described further in Concepts: Requirements.
For each of these dimensions, one or more individual types of tests (see Concepts:
Types of Test) should be implemented and executed during one or more of the
different stages of test (see Concepts: Stages of Test).
