In order to help the PSA Peugeot Citroën transformation quality department implement a continuous improvement process, a documentation system compliant with ISO 9001 requirements and consistent with the PSA Group's SMQ was created. It is essential for them to be able to control their operational processes and their interactions with other PSA processes. Controlling these two elements improves efficiency in transformation quality management. It also enables them to meet the requirements of the ISO 9001 quality management system standard.
