Abstract
The ever greater pressure of competition to which enterprises are subjected has made the process continuous improvement a crucial issue today. For this reason it should be useful to compose the business processes reusing previously modeled business process parts characterizing them according to the current market needs. This work presents an approach based on the use of Business Process Lines (BPL) to compose and characterize a business process according to different contexts reusing existing process parts. The approach has been applied to realize a BPL for the Software extraordinary maintenance. This BPL can be used to model different process variants of the Software extraordinary maintenance processes corresponding to different context profiles. The results demonstrate the approach applicability in a real case and underline that it allows to reuse and specialize the same process parts for many different contexts.
