A Multiple Views Model for Variability Management in Software Product Lines

Abstract

\\With current trends towards moving variability \nfrom hardware to software, and given the increasing \ndesire to postpone design decisions as much as is \neconomically feasible, managing the variability from \nrequirements elicitation to implementation is \nbecoming a primary business requirement in the \nproduct line process. Nowadays, a medium size \nsoftware system may encompass hundreds if not \nthousands of variability points introducing a new level \nof complexity that current techniques struggle to \nmanage. In this paper, we present a new approach to \nvariability management by introducing a multiple \nviews model (4VM) where each view caters for specific \nset of concerns that relate to a particular group of \nstakeholders.
