A Method of Translating Business Use Cases into System Use Cases

Business use cases (BUC) capture functional business requirements at an organization level, while system use cases (SUC) capture functional system requirements at a system level. Thus, a technique of translating business use cases into system use cases provides poor traceability between the business requirements and corresponding system functionality. In this paper we present a 7-Step method for translating a business use case into possible system use cases. A BUC template approach is shown for documenting the process. In doing so, we show a way to achieve much needed traceability between the business requirements and system functionality.
