This paper presents the second part of a study conducted at DMR Consulting Group during the development of a corporate memory. It presents a comparison of four major formalisms for the representation of business processes: UML (Unified Modeling Language), PIF (Process Interchange Format), WfMC (Workflow Management Coalition) framework and conceptual graphs. This comparison shows that conceptual graphs are the best suited formalism for representing business processes in the given context. Our ongoing implementation of the DMR corporate memory — used by several hundred DMR consultants around the world — is based on conceptual graphs, and preliminary experience indicates that this formalism indeed offers the flexibility required for representing the intricacies of business processes.
