A UML Profile for Software Requirements Prioritization

The increasing complexity of software systems makes Requirements Engineering an important phase in a system's development life cycle. When RE is carried out poorly, multiple problems may arise, such as failures, cost overrun and delays. In this context, prioritization is of significant importance to organize requirements in their order of comparative significance and consequent development releases. It is the most important step taken in making fundamental resolutions so as to increase the commercial significance of a system. Evaluating requirement prioritization in model-driven context is a super difficult task. Hence, there exists a solid need for a model-based approach that allows for the ranking procedure in SDLC. This article introduces UML profile for Analytic Hierarchy Process (AHP); to rank the software requirements in the context of model-driven engineering. Mapping its basic concepts into stereotypes to extend SysML's Requirement's Diagram. Thus, providing a way of ranking requirements in the model-driven context for the first time. AHP is a well-proven process for collaborative decision making to achieve better outcomes. Later, the applicability of this profile is authenticated through BuyMobilePhone case study.
