Um processo ágil de engenharia de requisitos com apoio de padrões de software

Abstract

Requirements engineering has evolved historically connected to the waterfall process model of system development. For agile processes its value continues to be essential to develop systems that really satisfy the customer needs. The iterative process model with high interaction with the customer is the key to preserve its importance. Organizational and requirements patterns can be used to guide the requirements engineer to obtain efficient processes to develop systems following principles and approaches of agile development. In the context of a real systems development organization a proposal of an agile process for system development iteratively and interactively using organizational and requirements patterns has been formulated and evaluated in a real case study. This proposal has been modeled in the SPEM meta-model and considers advancing the application of software metrics to the requirements phase in order to better plan following iterations. The team that worked in the evaluation has been recruited internally in the organization and the author of the proposal and of this dissertation has also been a member of the organization. He trained his colleagues and followed and recorded the evaluation conducted. A questionnaire has been formulated and applied to the team and the results of this application are reported here. Some of the characteristics of the proposed process have been incorporated to the organization systems development practice and some are being considered for incorporation with the necessary adaptation. These are here commented together with the team opinion about the SPEM modeling and advanced application of software metrics.
