A Scenario-based Problem Decomposition

Problem analysis has long been recognized as key to requirements engineering, for which Problem Frames approach offers a structured way by means of providing a generic paradigm for analyzing problems of various types. Problem decomposition is an important concern in structuring problem which has also been recognized as the key to mastering problem size and complexity. However at present it still lacks of feasible and effective ways for decomposing problems. In this paper we propose a scenario-based approach for tackling the issues on problem decomposition. A problem decomposition process is suggested. And a small case has been used to show the feasibility of this approach.
