The use of aggregation operator: a tool for software requirement prioritization

Abstract

A key goal of any engineering and software engineering in particular, is the quality of the final product. Software quality as an information system is often determined by the ability to meet the needs of customers and end users, as obtained as software requirements. To satisfy that needs is important a correct requirement engineering process in general, and a correct requirement prioritization in particular: Prioritizing software requirements is a complex decision making process. Traditional approaches do not perform aggregation of criteria with sufficient flexibility and adaptability lo the specific contexts of organizations. In this paper we propose a requirements prioritization method that uses aggregation operators far information fusion and the analytic hierarchy process. The proposal allows the inclusion of aspects such as the importance of the criteria and optimist/pessimism level. To demonstrate the applicability of the proposal case study is developed. The paper ends with further work recommendations for extending the method.
