Abstract— Many defects may arise during software product lines such as inconsistency, incorrectness and ambiguity. In our work, we are interested ina specific defect, which is duplication in features since it has received little attention in literature. In previous work, we proposed a conceptual framework that describes the different processes to follow in order to produce duplication-free feature models. We also implemented a tool support called FDDetector based on this framework with the aim of detecting and correcting duplication introduced in feature models by new product line evolutions. To evaluate this tool, we have adopted a CRM product line as a case study. In this paper, we explain the motivationsbehind choosing a case study from the CRM field,and we present the results of atest performed on an evolution related to this product line.

Index Terms— Feature duplication, customer relationship management, software product line, case study.
