PREMIeR: Um Processo de Elicitação e Modelagem da Variabilidade de Requisitos para Linhas de Produto de Software Dinâmicas

Abstract

Dynamic Software Product Lines (LPSD) are an extension of Software Product Lines (LPS), which in turn represent a set of systems that share a set of common assets and satisfy the needs of a given market segment or mission . LPSDs have been used as a strategy to produce complex systems, which require run-time adaptations, such as context-sensitive systems. For the development of a LPSD, domain engineers must pay attention to the identification and modeling of dynamic aspects and to the concept of variability. However, there are still gaps related to techniques and approaches that promote requirements elicitation and modeling for LPSDs. In this context, this paper aims to present a process of elicitation, modeling and variability management for LPSDs. The process proposed in the present work uses techniques of traditional requirements coupled with techniques directed to representation in LPSDs of the requirements, contexts and adaptations. For the definition of the process, non - systematic studies of the literature were carried out in order to identify techniques, approaches and tools used in Requirements Engineering of LPSD domain systems. The validation of the elaborated process was obtained by means of an observation study of the application of the PREMIeR process and indicates the possibility of identifying the elements of a LPSD through its application.
