Identifying Fundamental Goals from Objects in a Scenario to Facilitate System Introduction

To introduce suitable and innovative information systems into our daily activity, we have to know actual goals of its stakeholders. However, requirements analysts cannot directly know such goals, and stakeholders usually cannot state them explicitly even with the help of why questions. Analysts can directly observe or know the way of tasks in the activity, i.e. scenario. In this paper, we propose an early requirements analysis method using a scenario and goals in a bottom up way. In the method, the analysts first identify superficial objects and their attributes from the scenario, and construct a superficial goal model. The analysts then identify conceptual objects which do not appear in the scenario by combining and generalizing the superficial objects and goals. On the basis of the objects and superficial goals, the analysts identify the fundamental goals of the stakeholders. We are applying the method to examples to confirm how it works.
