Noriyuki Kushiro, Takuro Shimizu, Ehira Tatsuya · Procedia Computer Science · 2016
Requirements for a system are often discovered during negotiation process for conflicts among stakeholders, rather than at the time when stakeholders are thinking about their own requirements uncritically in a requirements meeting. Conflicts could be utilized as a driving force to discover significant functional and/or non-functional requirements for the system, by handling conflicts in the requirements meeting appropriately. In this paper, we propose a support tool for discovering conflicts, called as an extended goal graph. We implemented a prototype of the tool and constructed an environment for analyzing requirements meeting. The prototype and the environment were applied to a requirements meeting on improvement of selling area in drugstore. Issues and solutions for practical use of the tool are discussed on the results of feasibility test.
