A Case Study on Product Line Architecture Evolution
Mikael Svahnberg, Jan Bosch · 1999
Product-line architectures present an imponant approach to increasing software reuse and reducing development cost by sharing an architecture and set of reusable components among a family of products. However, evolution in product-line architectures is more complex than in traditional software development since new, possibly conilicting, requirements originate from the existing products in the product-line and new products that are to be incorporated. In this paper, we present a case study of product-line architecture evolution. Based on the case study, we develop categorizations for the evolution of requirements, the product-line architecture and product-line architecture components. Subsequently, we analyze and present the relations between these categorizations. 1
