This document provides an overview of the ISO/IEC SQuaRE standards for software quality. It describes the structure and contents of the SQuaRE series, which includes standards for quality models, measures, requirements, and evaluation. The SQuaRE series improves upon earlier ISO/IEC 9126 and 14598 standards by consolidating and reorganizing the documents into a unified framework.
