GB/T 25000.20-2021 Active

This part of GB/T 25000 specifies the framework for conducting quality measurement work. The content of this part is as follows: -- Quality measurement reference model; -- Relationships between different types of quality measures; -- Guidelines for selecting quality measures; -- Guidelines for constructing quality measures; -- Guidelines for planning and executing measurements; -- Guidelines for applying measurement results. This part also provides considerations for selecting quality measures and quality measurement elements (see Appendix A), evaluation of measurement reliability and quality measurement validity (see Appendix B), compilation of quality measurement elements (see Appendix C), normalization of quality measurement functions (see Appendix D), and the measurement information model in ISO/IEC/IEEE 15939 (see Appendix E). This part can be used to design, identify, evaluate, and implement measurement models for system and software product quality, usage quality, and data quality. The reference model can be used by developers, customers, quality assurance personnel, and independent evaluators, especially those responsible for specifying and evaluating the quality of information and communication technology systems.
