Enterprise Modeling

[Ray]

I just don't see the whole solution:
I am in a company which provides engineering, procurement and construction
management services to the chemical industry. I would like to develope some
visual support to discuss on-going workflow and integration projects. I
have read a few books on UML and have used it for specific software and work
process modeling. But for the big picture, I don't see how to put it all
together.

I would like to start with a high level diagram which shows the interactions
(static) between the company and the rest of the world. I imagine a diagram
showing the different groups (sales, marketing, HR, accounting, engineering,
purchasing, etc) and their interactions with the rest of the world. I would
like to be able to expand this diagram (click to a new page) to include more
detail. Maybe, it should start with the company as a circle/square with
interaction radiating out to the client base, specific customers, the
community (for HR), suppliers, etc. Further, this continued detailing
should be drillable to expose further and further details down to specific
work processes.

None of this seems to fit the UML views. What are these types of views
called? How do I find some examples? I would like to find detailed,
extensive examples.

All help would be appreciated.

Use case diagrams are usually a good way to start off a UML diagram on a
top-level view.

The Use Case diagram(s) can show how the different groups like
Clients/Groups interact with a Process.
The Process can then be drilled down into specific UML diagrams and
workflows.
