Abstract

Decision support system in requirements engineering plays an important role in software development life cycle. The relationship between functional and non-functional requirements is the key in resolving conflicts in requirements gathering phase. In this paper, we discuss the effect of nonlinearity rating while converting the contribution links to quantitative values. We use our goal-oriented requirements engineering (GORE) method to identify the soft goals. Analytic hierarchy process (AHP) is then used to prioritize the soft goals. The output of AHP is used as input to technique for order of preference by similarity to ideal solution (TOPSIS) which produces a metric which decides the best alternative among the candidates. We illustrate the process and analyze the nonlinearity effect for meeting scheduler application. © 2014 Springer India.
