ISO/IEC 25040:2011 contains requirements for the evaluation of software product quality . It provides a process description for evaluating software product quality and states the requirements for the application of this process.
This makes evaluation of software quality is a structured affair
The evaluation process can be used for different purposes. The process can be used for the evaluation of the quality of pre-developed software, commercial-off-the-shelf software or custom software and can be used during or after the development process.
ISO/IEC 25040:2011 establishes the relationship of the evaluation reference model to the SQuaRE documents as well as shows how each SQuaRE document should be used during the activities of the evaluation process.
It is intended for those responsible for software product evaluation and is appropriate for developers, acquirers and independent evaluators of software products. These three different approaches are detailed in ISO/IEC 14598-3, ISO/IEC 14598-4, and ISO/IEC 14598-5.
