Is the ISO/IEC 25000 series standard mature or not? The assessment of

The ISO/IEC 25000 series of standards, also known as SQuaRE (System and Software Quality Requirements and Evaluation) aims to set the benchmark, define the quality requirements, the implementation of their assessments and the way in which quality requirements will be evaluated for software. SQuaRE is the result of the "merging of two (2) standards"; ISO/IEC 9126, which defines a quality model for the evaluation of a software product, and ISO/IEC 14598, which defines the software product evaluation process. SQuaRE is divided into a series of standards, with five (5) divisions: ISO/IEC 2500n, 2501n, 2502n, 2503n, 2504n and 2505n. It must be noted that, despite the definition and description of the ISO/IEC 25030 standard since 2007, it seems to be confused and not aligned with the other SQuaRE standards.
