Users submit high-level descriptions of simple, incomplete, or incorrect business processes in softcopy form illustrating the orchestration of services (or the control flow), and get prompted with suggestions to specify the services' data flow. The method and systems herein assist in specifying data flowing between services, but also detects missing edges and services, for which the method and systems herein also provide data flow suggestions. The suggestions are computed and ranked using heuristics, and displayed through a wizard to the user.
