Demands and wishes from managers, users and other stakeholders, or in other words the business requirements, are the basis for any organizational change project. The quality of the enterprise architecture, the project architectures, and the IT systems developed based on these architectures, is largely determined by the way the business requirements are fulfilled. Also within TOGAF9 requirements are important. This requires a systematic approach for requirements analysis and management; especially for the business requirements that determine the contents of the enterprise architecture, and not only for the detailed IT requirements. In this presentation we will present our approach for business requirements management, and show how this can be modeled and analyzed using the ArchiMate language and supporting tool.
