Abstract

Methods, apparatus and computer program products decompose a service process into service process operations; filter the service operations based on at least one pre-determined criterion; identify at least one different service process operation to be used to replace an existing service process operation; and replace the existing service process operation with the at least one different service process operation. The service process can be decomposed using specific service features derived from reference service processes. The pre-determined criterion used to filter the service operations can constitute a service level; a service category; or a service process feature. A service process feature describes core functionality of the service.

8. The system of claim 1 wherein when the at least one computer program is executed the system is further configured to replace the existing service process operation with the at least one different service process operation.

9. The system of claim 1 wherein the existing service process operation further comprises a plurality of service process operations which together constitute a service.

10. The system of claim 1 wherein the at least one pre-determined criterion comprises a service level.
