Decision-making method family MADISE: Validation within the requirements engineering domain

Information Systems (IS) engineering (ISE) processes contain steps where decisions must be made. Moreover, the growing role of IS involves requirements for their engineering, such as quality, cost, time, and so on. On the one hand, considering these aspects implies that the number of researches dealing with decision-making (DM) in ISE increasingly grows. On the other hand, many DM methods exist and are applied in several fields of ISE. The main characteristic of these applications is that they resolve one DM problem at a time. We have developed a generic DM approach MADISE, which aims at guiding IS engineers through DM activities. The goal of this paper is to check the completeness and flexibility of MADISE by comparing it with the five well-known requirements prioritization approaches.
