AHP_GORE_PSR: Applying analytic hierarchy process in goal oriented requirements elicitation method for the prioritization of software requirements

Abstract

Goal Oriented Requirements Engineering (GORE) is concerned with the identification of goals of the software according to the need of the stakeholders. In GORE, goals are the need of the stakeholders. These goals are refined and decomposed into sub-goals until the responsibility of the last goals are assigned to some agent or some software system. In literature different methods have been developed based on GORE concepts for the identification of software goals or software requirements like fuzzy attributed goal oriented software requirements analysis (FAGOSRA) method, knowledge acquisition for automated specifications (KAOS), i∗ framework, attributed goal oriented requirements analysis (AGORA) method, etc. In AGORA, decision makers use subjective values during the selection and the prioritization of software requirements. AGORA method can be extended by computing the objective values. These objective values can be obtained by using analytic hierarchy process (AHP). In AGORA, there is no support to check whether the values provided by the decision makers are consistent or not. Therefore, in order to address this issue we proposed a method for the prioritization of software requirements by applying the AHP in goal oriented requirements elicitation method. Finally, we consider an example to explain the proposed method.
