My point is that a process execution might not have an agent. Not that the agent is unknown, but that there is no controlling entity that caused the process to occur. Reza mentioned the idea of natural forces as agents. Maybe that's fine. I'm just not sure that that will be understandable to people who aren't familiar with control systems theory (like myself).
