Research On Goal-Oriented Requirement Analysis Methodology Based On I*

In this dissertation, we introduce a Goal-Oriented Requirement Analysis Methodology. Now, more and more people prefer to adopt a goal-oriented requirement analysis methodology in requirement engineering. During the progress of RE, the goal is used in many activity of reasoning. In some RE framework, the goal is very critical, and in other framework, they also play important role. They drive the elaboration of requirements to support them. They provide a completeness criterion for the requirements specification; the specification is complete if all stated goals are met by the specification. Goals are generally more stable than the requirements to achieve them.First, we introduce some approach in RE, and reviews some attempts to address those inadequacies, with special emphasis on a goal-oriented approach. Two complementary frameworks have been proposed for integrating goals and goal refinement in requirements models: a formal framework and a qualitative one.The i* framework proposes an agent-oriented approach to requirements engineering centering on the intentional characteristics of the agent, i* framework is a qualitative framework. We think that i* framework is inadequate to evaluate requirement specification. In order to deal with the question, we reform the qualitative requirement analysis methodology as a quantitative requirement analysis methodology.Finally, in order to fulfill the process of integrating goal and softgoal, we use reformed i* framework to support the process.
