PROREQ - Um guia facilitador para a implantação dos processos de gestão de requisitos

Abstract

Requirements management processes have a great impact on the final product conception and are directly related to customers’ satisfaction, as the expected behavior of the software is defined during them. Their products serve as a basis for the processes executed subsequently and, thus, the probability of failure is higher when faults occur during the elaboration of the software requirements. However, it has been observed that these processes are one of the richest sources of problems found during software development. This motivated the appearance of models for improving software development processes, such as the Capability Matutity Model Integration – Development (CMMI-Dev), which act as guides for continuously improving the organization development processes. Nevertheless, the abstraction level of the models is not always specific enough to guide the organization collaborators that are not familiar with the software engineering body of knowledge. Financial aspects also make the utilization of these models more difficult, because to deploy these improvements is often expensive and can be unfeasible for small and medium organizations. This work presents a guide, named PROREQ, whose main goal is to ease the deployment of improvements in the requirements processes of small organizations. It is composed of: a set of good practices classified according to the organization structure of CMMI-Dev process areas Requirements Development and Management; a deployment strategy, based on ISO/IEC 15504 strategy and on a set of practices coming from empirical works related to software process improvement; and an evaluation model based on ISO/IEC 15504 and on the evaluation method of the Brazilian software process improvement method (MPS.BR). A case study is described to present the results of applying the PROREQ guide in a small software development organization.
