What is ISO/IEC 25020 – SQuaRE about ?
ISO/IEC 25020 provides a framework for developing quality measurement and contains quality measurement reference model relationships between different types of quality measures guidelines for selecting quality measures, constructing quality measures, planning and performing quality measurements.
ISO/IEC 25020 can be applied for designing, identifying, evaluating and executing the measurement model of system and software product quality, quality in use, data quality and IT service quality. This reference model can be used by developers, acquirers, quality assurance staff and independent evaluators essentially by people responsible for specifying and evaluating the quality of information and communication technology (ICT) systems and services.
Who is ISO/IEC 25020 – SQuaRE for ?
ISO/IEC 25020 on systems and software Quality Requirements is relevant to:
- Software Engineers
- Organizations that require software and systems support
- Any entity in charge of maintaining the Software Development Life Cycle
- Testers and Designers
Why should you use ISO/IEC 25020 – SQuaRE ?
A quality measure is a way to evaluate the performance of software, checking for errors and improvements.
ISO/IEC 25020 specifies a framework for developing quality measurement and software evaluation.
ISO/IEC 25020 specifies four quality measurement methods that apply to software products, IT systems, and software used by humans, as well as systems and IT services that support those systems.
Overall, ISO/IEC 25020 provides a framework that you can use to develop software so that bugs and errors can be identified during the testing stage, making the end product better and improving the user experience.
