An Automated Approach to Embrace Changes During Use case Model Evolution

Use case model is subject to changes throughout the software development life cycle. Impacts of these changes affect directly the requirements and consequently the resulted system. Scrapping and replacing use case is expensive; in this paper we proposed a solution that integrates changes in use case in requirement phase. This solution combines independent enhancements to some version of a use case into a new version that include the enhancements and the old use case. CASE tool implementation and experimental evaluation of the proposed approach showed promising results in terms of software development time saving and better use case models integrity.
