Prioritizing Non-functional Concerns in MAMIE Methodology

Abstract

The increasing globalization of markets and companies demands more and more investigations of distributed requirements engineering. Requirements elicitation is organized as one of the most critical activities of the requirements engineering process. It is a difficult task enough when done locally, but it is even more difficult in a distributed environment due to cultural, language and time zone boundaries. In our previous research we have proposed a methodology to elicit requirements for an inter-company co-operative information system. In this methodology the analyst must specify a priority value for each non-functional concern that may be considered in the inter-company co-operation process. To do, s/he must take in consideration several viewpoints of concerned stakeholders. In order to help the analyst to better accomplish this task, we propose in the present paper a process based on Grunig and Hunt model to identify concerned stakeholders and Michell et al model to prioritize them. A mathematical function proposed to return the final non-functional concern priority constitutes a cornerstone of this process. Preliminary results suggest that this process is of valuable help to analysts during requirements elicitation.
