This system model is applicable to the complete human-computer system , including both computer systems in use and software products in use.

b) A product quality model composed of eight characteristics (which are further subdivided into subcharacteristics) that relate to static properties of software and dynamic properties of the computer system . The model is applicable to both computer systems and software products .

The characteristics defined by both models are relevant to all software products and computer systems . The characteristics and subcharacteristics provide consistent terminology for specifying, measuring and evaluating system and software product quality. They also provide a set of quality characteristics against which stated quality requirements can be compared for completeness.
