A roles and permissions matrix is a technique that defines the roles and responsibilities of the stakeholders involved in a business process, and the level of authority and access they have to the information and resources required to perform their tasks. A roles and permissions matrix can help the BA to model the people involved in the contracting process, and identify any gaps, overlaps, or conflicts in their roles and permissions. A roles and permissions matrix can also help to improve the efficiency, effectiveness, and security of the process, and ensure compliance with the policies and regulations. A roles and permissions matrix is part of the Requirements Analysis and Design Definition Knowledge Area in the BABOK Guide. Reference: 1, 2 (pages 31-32), 3 (pages 13-14)
