From Business Process Models to Use Case Models: A Systematic Approach

One of the most difficult, and crucial, activities in software development is the identification of system functional requirements. A popular way to capture and describe those requirements is through UML use case models. A business process model identifies the activities, resources and data involved in the creation of a product or service, having lots of useful information for developing a supporting software system. During system analysis, most of this information must be incorporated into use case descriptions. This paper proposes an approach to support the construction of use case models based on business process models. The proposed approach obtains a complete use case model, including the identification of actors, use cases and the corresponding descriptions, which are created from a set of predefined natural language sentences mapped from BPMN model elements.
