Comparative study of Goal-Oriented Requirements Engineering

Requirements Engineering is a sub discipline of Software Engineering, which is an important and vital phase in the overall software engineering life cycle. Software as a final product is deemed to fail if it does not fulfill the needs of its users. A number of contributions have been made to refine the requirements engineering process. Most of them attempted to link requirements to goals. This new trend is called as Goal-Oriented Requirement Engineering (GORE). A number of goal-oriented RE methods have been subsequently derived by various researches. This paper reviews some of the significant research works done in GORE. The comparative study may serve as a guide for readers to select an appropriate goal-oriented technique for fulfilling his/her requirements engineering needs.
