Techniques for extending a process model with specification of information consumed. A receiving operation receives specification of process information consumed by a process implementation of the process model. Another receiving operation receives specification of activity process information consumed by activities employed by the process implementation of the process model. The information consumed is information that is or needs to be used without being passed through exposed interfaces. A generating operation automatically generates an extended process model using a computer processor. The extended process model includes specification of exposed interfaces, the process information consumed by the process implementation, and the activity information consumed by the activity implementation. Further embodiments includes techniques for identifying information inconsistencies in the extended process model if the information consumed not available as called for by the extended process model.
