Uma ferramenta multicritérios de priorização de requisitos baseada na técnica Analytic Hierarchy Process

Abstract

Over time, companies and businesses have constantly evolved, which makes systems and the way to develop software evolve together, becoming increasingly interactive the way to create products. Thus, it is important to have a consistent requirements prioritization phase, which takes into account the stakeholders requirements and development conditions. Doing good prioritization can define whether product development will be successful or not. The requirements prioritization system presented in this paper aims to assist decision makers in the management and prioritization of functional requirements of their projects., taking into account the prioritization considerations. This system will make it possible to use the requirements prioritization technique Analytic Hierarchy Process based on multicriteria in an automated way, facilitating the use of the technique. For this, it was necessary to make a selection of the criteria, through a study in the literature and interviews with three specialists in the area of requirements engineering. For the construction of the tool, an analysis of the domain was made, followed by the survey of the functional requirements and the elaboration of the documentation. To validate the proposed solution, a case study was carried out in a project of the software factory of the Catholic University of Salvador, the case study had four phases, where the first was the identification of the participants’ profile, the second was the prioritization of requirements using an auxiliary spreadsheet, in the sequence, the participants carried out the prioritization using the tool described in this paper, finally, a questionnaire was applied to collect information about the priorities and impressions of the participants. The results obtained in the case study demonstrate that the tool was able to automate the technique of the Analytical Hierarchy Process and facilitate the process of prioritizing requirements. The criteria presented in this paper are also suitable for the context of the project in which they were used. Participants reported that the prototype of the tool is intuitive and practical, showing that it has the potential to be improved for commercial use.
