Concepts: Quality Dimensions
Quality, as discussed in 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 it's measured.
In the RUP, we categorize quality using the FURPS+ model [GRA92]:
- Functionality
- Usability
- Reliability
- Performance
- Supportability
- + (and others)
This is the same categorization scheme that we use in RUP 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 levels of test (see Concepts: Stages of Test).
