Due to the high competitiveness companies face in occupying positions as world business leaders, they must develop strategies to improve their processes while implementing certification in quality management systems under the ISO 9001 standard. This paper is based on a systematic analysis of the requirements of the standard ISO 9001 and recognised methodologies worldwide in process improvements, such as lean manufacturing, business process reengineering, Lean Six Sigma, and business process management. In which a framework of best organisational practices was designed. Here it was possible to identify some activities of the certification processes that could be improved using this framework when implementing a management system, so that it can be used as a control concept to increase the probability of obtaining processes that promote quality from the implementation of the QMS.
