1. A method, embodied in at least one computer, for generating a separate runtime compliant partner process for a given original process, wherein both processes are dedicated to interact with each other, the computer performing the steps comprising: identifying all activities of the original process interacting with said separate partner process; determining, at least in part according to a pre-defined catalogue of mapping rules, whether an activity in said original process is able to be mirrored in said separate partner process, wherein said activity in said original process is able to be mirrored in said separate partner process in the event that a mirrored activity corresponding to said activity in said original process can be found in said catalogue of mapping rules, wherein said determining further includes determining whether said activity in said original process comprises a BPEL switch activity, and determining that said activity in said original process is not able to be mirrored in said partner process responsive to a determination that said activity in said original process comprises a BPEL switch activity; responsive to a determination that said activity in said original process is able to be mirrored in said separate partner process, generating said mirrored activity corresponding to said activity in said original process and inserting said mirrored activity corresponding to said activity in said original process into a result structure tree; and responsive to a determination that said activity in said original process is not able to be mirrored in said separate partner process, dissecting said activity in said original process into sub-activities which can be mirrored in said separate partner process and generating a respective mirrored sub-activity for each of said sub-activities, inserting said mirrored sub-activities into said result structure tree, and, in the case where said activity in said original process comprises a BPEL switch activity, transforming said BPEL switch activity into a cascade of BPEL pick activities in said result structure tree to connect said mirrored sub-activities.
