My understanding is as follows:

In order for an operation to appear in that list, that operation needs
to have code added to its implementation for it to be "enabled" for
process, which causes it to call into the process framework for
"pre-condition" actions before invoking the operation, and then again
after invoking the operation for "post-condition" actions.

So you'd need to modify the server code to make a new operation
available for process guidance.

But you can contribute new pre-conditions and new post-conditions to
existing operations, by following the instructions on jazz.net.

You have the option to define some operation behaviour for roles in
the project area (under Process Configuration -> Team
Configuration -> Operation Behaviour). As far as I can see the
list of operations is fixed though.

Does anybody know, if it is possible to add operations to the list?

E.g. a "Create Work Item" operation with the behaviour of
displaying a guidance in the Team Advisor view explaining how to
write a good User Story. Or a guidance telling the user how the
"Done" state of a Work Item should be defined.
