DANSK DSF/ISO/IEC FCD 25010 PDF

This International Standard defines: a) 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, b) A quality in use model composed of five characteristics (some of which are further subdivided into subcharacteristics) that relate to the outcome of interaction when a product is used in a particular context of use. This system model is applicable to both computer systems in use and software products in use. The characteristics of both models apply to all software products and software intensive 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. ISO/IEC 25012 contains a model for data quality that is complementary to this model. The scope of the models excludes purely functional properties (see C.5), but it does include functional suitability (see 6.1). 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 audit. The models can, for example, be used by developers, acquirers, quality assurance 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: - identifying software and system requirements; - validating the comprehensiveness of a requirements definition; - identifying software and system design objectives; - identifying software and system testing objectives; - identifying quality control criteria as part of quality assurance; - identifying acceptance criteria for a software product and software intensive computer system; - establishing measures of quality characteristics in support of these activities. The quality models can be used in conjunction with ISO/IEC 12207 and ISO/IEC 15288, particularly the processes associated with requirements definition, verification and validation with a specific focus on the specification and evaluation of quality requirements. ISO/IEC 25030 describes how the quality models can be used for software quality requirements, and ISO/IEC 25040 describes how the quality models can be used for the software quality evaluation process.
