Software evolution in model-driven product line engineering

Abstract

New requirements and technology changes lead to continuous changes of the assets comprising a software product line. Since the product line represents a large number of potential products (or already deployed products) in a given domain, managing these changes becomes a key issue when dealing with evolution. We present a framework to support the development and evolution of highquality software product lines. The framework is based on several interrelated models or system views (eg, functionality, variability, quality) and a production plan defined by model transformations that generate a software system that meets both functional and quality requirements. We used our framework to develop a software system for the automotive domain.
