摘　　要： 本文提出了一种企业信息系统(Enterprise Information System,缩写为EIS)环境下基于场景的协同需求诱导方法,以场景为核心组织不同的利益相关者,使其能够主动且有效地参与需求获取的过程;并给出了具体的步骤指导需求专家如何逐步从现状场景到期望场景再到用况诱导出用户的需求;展示了如何从场景的结构化描述中抽取活动图、场景-角色-数据关系图,以及如何使用这两类视图来对场景描述和需求的完整性、一致性等进行验证. Researches on requirement engineering focus more on the requirement analysis and requirement specification, while less on requirement elicitation. In this paper we propose a scenario-based collaborative requirements elicitation approach for Enterprise Information Systems（EIS）. In this approach, we use scenario to organize different stakeholders, to facilitate the collaboration among them and thus change the elicitation pattern from traditional repuirement experts centered way to stakeholder-equal way. This approach proposes the elicitation steps as ： the stakeholders should first construct the as-is scenario, then to-be scenario and use- Case,and elicit the requirement based on the to-be scenario.. We also present how to extract scenario-role-data view from natural language description and activity diagram from semi-formal description, and use these two views to validate the completeness and conflict free of the scenario descriptions and the users＇ requirements.
