Approaching Non-functional Properties of Software Product Lines: Learning from Products

Approaching the configuration of non-functional properties (NFPs) in traditional software systems is not an easy task, addressing the configuration of these properties in software product lines (SPLs) imposes even further challenges. Therefore, we have devised the Feedback Approach, which extends the traditional SPL development techniques in order to improve the configuration of NFPs. In this work we present the general guidelines of our approach and also we show the feasibility of the idea by presenting a case study using the Linux Kernel.
