Non-Functional Properties in Software Product Lines: A Reuse Approach

Abstract

Software Product Line Engineering (SPLE) emerges for software organizations interested in customized products at reasonable costs. Based on the selection of features, stakeholders can derive programs satisfying a range of functional properties and non-functional ones. The explicit definition of Non-Functional Properties (NFP) during software configuration has been considered a challenging task. Dealing with them is not well established yet, neither in theory nor in practice. In this sense, we present a framework to specify NFP for SPLE and we also propose a reuse approach that promotes the reuse of NFP values during the product configuration. We discuss the results of a case study aimed to evaluate the applicability of the proposed work.
