Introducing product line engineering is an investment that has to be planned for. This investment also comprises an investment into the scoping activities. Scoping, also called product line planning can be defined as the process of deciding in which parts of an organisation's products, features and domains systematic reuse is economically useful. The basis of scoping is the domain knowledge of domain experts. In existing product line engineering approaches, the scoping information is elicited interactively from domain experts, which is an effort intensive task due to the large number of experts that are involved and the time needed for workshops and interviews.
In this dissertation we present the CaVE approach (Commonality and Variability Extraction) as a solution to this problem. The approach supports scoping and the introduction of product line engineering in a development organisation by systematically eliciting scoping information from user documentation. Our main goal is expert load reduction, to improve the feasibility of product line introduction in industrial context.
We could show the completeness and correctness of the approach in three industrial case studies and one experiment. With the empirical validation we could show an expert load reduction of over 40% percent when using the approach in a real product line context.
Prof. Dr.-Ing. habil. Peter Liggesmeyer has been holding a chair in Software Engineering: Dependability in the Department of Computer Science at the Technical University of Kaiserslautern and has been director of the Fraunhofer Institute for Experimental Software Engineering (IESE) since 2004. He is founder and speaker of the Fraunhofer Alliance Embedded Systems. Prof. Liggesmeyer has received several scientific awards, including the Software Engineering Award of the Ernst Denert Foundation in 1993. He is the author of more than 100 scientific articles and books, especially the standard reference work "Software Quality" (2002, 2nd edition 2009). For more than 20 years, Prof. Liggesmeyer has now been in frequent demand as a lecturer for industry seminars and has been advising many leading companies in matters of technology issues.
