ISO 9001 - Clause 9 Performance Evaluation

ISO 9001:2015 Clause 9, "Performance Evaluation," outlines the requirements for an organization to assess the performance and effectiveness of its quality management system (QMS). It mandates regular monitoring, measurement, analysis, and evaluation of the QMS and its processes, as well as customer satisfaction, to ensure compliance with specified requirements and to identify areas for improvement. This clause includes conducting internal audits (9.2) and management reviews (9.3), along with the necessity to determine, collect, and analyze appropriate data (9.1) to evaluate the performance of the QMS. Essentially, it provides a framework for organizations to ensure their QMS is functioning as intended and is continually improving.
