ISO/IEC 25010:2011

Systems and software engineering - Systems and software Quality Requirements and Evaluation (SQuaRE) - System and software quality models

ISO/IEC 25010:2011 defines: 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 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. 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. 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. ISO/IEC 25012 contains a model for data quality that is complementary to this model. 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: 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.

ISO/IEC 25012:2008

Software engineering - Software product Quality Requirements and Evaluation (SQuaRE) - Data quality model

ISO/IEC 25012:2008 defines a general data quality model for data retained in a structured format within a computer system. ISO/IEC 25012:2008 can be used to establish data quality requirements, define data quality measures, or plan and perform data quality evaluations. It could be used, for example, to define and evaluate data quality requirements in data production, acquisition and integration processes, to identify data quality assurance criteria, also useful for re-engineering, assessment and improvement of data, to evaluate the compliance of data with legislation and/or requirements. ISO/IEC 25012:2008 categorizes quality attributes into fifteen characteristics considered by two points of view: inherent and system dependent. Data quality characteristics will be of varying importance and priority to different stakeholders. ISO/IEC 25012:2008 is intended to be used in conjunction with the other parts of the SQuaRE series of International Standards, and with ISO/IEC 9126-1 until superseded by ISO/IEC 25010.
