Abstract

This paper describes industrial experience with the evolution of a software product line of multifunction printers, specifically, experience with modification of the variability model in ways that alter constraints and other relationships between variation points. Evaluating the impact of such changes has proven to be difficult in practice and is an unsolved problem for the organization described.
