GOASREP: Goal oriented approach for software requirements elicitation and prioritization using analytic hierarchy process

Abstract

Software requirements elicitation is a valuable process for the identification of software requirements according to the need of different types of stake-holders. There are different methods for the elicitation of software requirements like traditional methods, group elicitation methods, goal oriented methods, etc. Among these methods, goal oriented methods have received much recognition by software requirements engineering community. On the basis of our literature review, we identify that “goal oriented requirements elicitation processes do not support how to select and prioritize the requirements using analytic hierarchy process on the basis of the cost and effort criteria”. Therefore, in-order to address this issue, we proposed a method, i.e. GOASREP, for the elicitation of software requirements using “goal oriented approach” and the prioritization of the elicited requirements using “analytic hierarchy process”. In the proposed method, we used function point analysis approach for the estimation of the cost of each requirement. COCOMO model has been applied to estimate the effort of each requirement. Finally, the usage of the GOASREP is explained using Institute Examination System.
