Software Quality Standards

ISO/IEC 25010:2011 Systems and software engineering — Systems and software Quality Requirements and Evaluation (SQuaRE) — System and software quality models.

• A quality-in-use model is composed of five characteristics (some of which are further subdivided into sub-characteristics) that relate to the outcome of interaction when a product is used in a particular context of use. This system model applies to the complete human-computer system, including both computer systems in use and software products in use.

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

• Product dev activities that can use 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/or software-intensive computer system;

  • establishing measures of quality characteristics in support of these activities.
