Using goals and customizable services to improve adaptability of process-based service compositions

When implementing (semi-)automatic business processes with services, engineers are facing two sources of variability. One source of variability are alternative refinements and decompositions of requirements. The other source of variability is that various (combinations of) services can be used to satisfy the same requirements. We suggest a method based on the use of a goal model and customizable services able to exploit these variabilities to design executable business process. This method improves the adaptability of the business process at runtime. We illustrate the contribution of our method with an example.
