Integrating an idea generation method into a goal-oriented analysis method for requirements elicitation

Abstract

This paper proposes an extension of goal-oriented analysis method where an idea generation method is combined. Goal-oriented analysis methods are one of the promising approaches for requirements elicitation. However, they have two major shortcomings; 1) little support for goal elicitation and decomposition into sub-goals and 2) no explicit support for collaborative activities by stakeholders to elicit goals. In particular, stakeholders as the knowledge source play an important role on eliciting requirements of high quality and all of them should participate in requirements elicitation activities. In our technique, an idea generation method like Brainstorming is used to identify sub-goals. The team of stakeholders focuses on a goal and generates the ideas related to the goal. And then the team groups the generated ideas together into sub-goals. These steps are intertwined by an idea generation method and all of the stakeholders can participate in idea generation and grouping tasks.
