The series of standards ISO/IEC 25000, also known as SQuaRE (System and Software Quality Requirements and Evaluation), has the goal of creating a framework for the evaluation of software product quality.

ISO/IEC 25000 is the result of the evolution of several other standards; specifically from ISO/IEC 9126, which defines a quality model for software product evaluation, and ISO/IEC 14598, which defines the process for software product evaluation. The series of standards ISO/IEC 25000 consists of five divisions.
