Evolving Industrial Software Architectures into a Software Product Line: A Case Study

Model-Driven Product Consolidation into Software Product Lines

“…Due to this, we do not support consolidating independently developed products, such as studies by Koziolek et al [6]. We assume the degree of changes in the product copies will have an influence on the results of our approach, which needs to be evaluated in future case studies.…”

Graph modelling of a refactoring process for Product Line Architecture design

“…An interesting work of Koziolek, Weiss and Doppelhamer [10] describes a reengineering approach to build the PLA to develop PC software for a robotics industry, based on the refactoring of three existing products. However, it lacks the description of a systematic process, being limited to expertise considerations; the PLA that is produced satisfies established architectural quality goals for the domain.…”

“…However, it lacks the description of a systematic process, being limited to expertise considerations; the PLA that is produced satisfies established architectural quality goals for the domain. Considering this case study [10], we propose in this work a systematic and repeatable derivation process, based on a refactoring approach and the use of the graph model described in section II.A, to construct a PLA. The bottom-up derivation of the PLA from the individual products is performed analysing automatically the RG associated to each product, and using a heuristic proposed by I. Bosch [15], on the choice of the main common functionality.…”

“…The bottom-up derivation of the PLA from the individual products is performed analysing automatically the RG associated to each product, and using a heuristic proposed by I. Bosch [15], on the choice of the main common functionality. Figure 1 shows three similar products of the robotics industry domain specified in UML [11], corresponding to the case study described in section II.B, adapted from [10]. Notice that UML 2.0 is used here as an ADL (Architecture Description Language); however, only static design aspects, a logical view of the architecture, are discussed in this work [12].…”

“…This reactive bottom-up process is based on the identification of different connected architectural intermediate configurations, starting from existing similar product architectures that will be part of the SPL family. The inspiration for this paper came from [10] with a case study in the robotics industry domain, where a PLA is manually developed. The model supporting our process is a graph or Refactoring Graph, denoted by RG.…”
