The UAF EA Project template doesn't seem to have a lot of use. The UAF Enterprise Architecture Guide, which--interestingly enough--actually has screenshots of this template, details doing things that the actual template doesn't let you do. There are also no solid example of this guide being used anywhere that I can find.
The following examples are all using the UAF Enterprise Architect within Cameo Systems Modeler 2022x with the UAF plugin.
One example of the non-usefulness...
This diagram (St-Mv) doesn't actually let you add drivers. Here are its options. Notice that "Driver" is not an option...
Another example: Step 0.2: Conduct problem framing.
This is a basic Content Diagram. What are we supposed to do with this?
There are many examples like this throughout the entire template. Very little of it makes sense when you actually start to use it. The guide page seems great on the surface, but it doesn't seem usable, and seems quite broken. You can't even create certain elements in certain packages where it seems to want them.
