Functional correctness - Degree to which a product or system provides the correct results with the needed degree of precision. Functional appropriateness - Degree to which the functions facilitate the accomplishment of specified tasks and objectives. 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. Although the scope of the product quality model is intended to be software and computer systems, many of the characteristics are also relevant to wider systems and services.
The scope of the models excludes purely functional properties, but it does include functional suitability. The scope of application of the quality models includes supporting specification and evaluation of software and software-intensive computer systems from different perspectives by those associated with their acquisition, requirements, development, use, evaluation, support, maintenance, quality assurance and control, and audit.
The models can, for example, be used by developers, acquirers, quality assurance and control staff and independent evaluators, particularly those responsible for specifying and evaluating software product quality. Activities during product development that can benefit from the use of the quality models include:. Proof returned by secretariat 60 Publication Check out our FAQs. Buy this standard. This standard was last reviewed and confirmed in Therefore this version remains current.
This system model is applicable to the complete human-computer system, including both computer systems in use and software products in use. 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.
