Abstract

Checkland's Soft Systems Methodology (SSM) can support strategic planning for business improvement. This involves the development of system models to identify the activities that an organisation must perform to meet its goals. Jacobson's Use-case modelling in the Unified Modelling Language (UML) is a requirements engineering technique that similarly leads to the identification of system activities, but driven by the needs of the system's 'users', rather than those of the system itself. This paper considers the potential gain from using these techniques in combination. One conclusion is that SSM can enhance UML, but requires careful integration of the techniques and associated models involved.
