Nowadays, the engineering of (software) systems has to comply with di erent standards, which often exhibit common requirements or at least a signi cant potential for synergy. Compliance management is a delicate, time-consuming, and costly activity, which would bene- t from increased con dence, automation, and systematic reuse. In this paper, we introduce a new approach, called SoPLE&Logic-basedCM. SoPLE&Logic-basedCM combines (safety-oriented) process line engineering with defeasible logic-based approaches for formal compliance checking. As a result of this combination, SoPLE&Logic-basedCM enables automation of compliance checking and systematic reuse of process elements as well as compliance proofs. To illustrate SoPLE&Logic-basedCM, we apply it to the automotive domain and we draw our lessons learnt.
