A Case Study on Product Line Architecture Evolution
- 1999
-
Konferensbidrag (refereegranskat)abstract
- Product-line architectures present an important 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 conflicting, 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.

Tidskriftsartikel (refereegranskat)abstract
- This paper discuss the results of two case studies from a technical perspective, concentrating on the evolution of software assets in two Swedish organizations that have employed a product-line architecture approach for several years. This paper describes and analyses the commonalities and differences of these two cases, emphasising categories of the evolution of the requirements, of the software architecture and of the software components. This paper concludes with three types of lessons learned about evolution in software product lines: three evolution categories are predominant, three other categories are less significant but still common, and seven guidelines for software product-line evolution emerge.
