Building a quality management system (QMS) relies heavily on two key steps: mapping and modeling business processes. The process approach, a core principle of QMS, emphasizes identifying and managing processes and their interactions systematically. This ensures achieving desired outcomes aligned with the organization’s policies and strategic goals. Following this approach, organizations need to establish, implement, maintain, and continuously improve their quality management system (SQM), encompassing all relevant processes and their connections, to meet regulatory requirements. This article aims to present our approach for extending the BPMN formalism by a quality dimension based on the MDA approach and on an ontological approach for the definition of a meta-model for the quality management which covers the ISO 9001 Norm.
