Managing engineering projects is becoming more complex especially when projects include networks of organizations. The complexity arises both from the growing number of relationships within a project as well as continual changes in project goals. The complexity impacts on process management as new ways are needed to manage the complex relationships and their continuing change. This paper proposes a systematic way to manage process complexity by developing the semantics to communicate within complex processes in meaningful ways. It then defines ways to implement these semantics in ways that allow users to create and change processes in terms natural to them. The paper considers the limitations of current collaborative technologies in supporting dynamic processes. The paper then describes the implementation on lightweight platforms and shows the application to supply chains, which many of which now require greater flexibility and collaboration
