SPEM is (I believe) SW Process Engineering Model.

Vivienne wants to invent a SPEM Metamodel (SPEMM?),

Conrad wants to reuse UML Metamodel facilities.

I'm not sure 'process metamodel' and "process model" mean the same thing to both parties, but Conrad argues that UML metamodels already exist for use by the tools that capture the info and activity of (software development) processes. I am sure this is not the end of the SPEMM discussion.

emphasizing various aspects of modeling dynamics. Activity diagrams are available

for modeling flows of outputs to inputs, including control, state machines

for reacting to events, and interactions for message-passing.

All support coordinating constructs such as decision and concurrency.
