From organisation chart to process chart

When business analysts come into a new business, they need to quickly understand the structure, people, products and processes in the company.

One of the key things I usually ask for is the organizational chart (aka organigram, organogram).
As a side note: it's amazing how often I either get incomplete or outdated diagrams. I wonder in that case how the heck people in their own organization understand the structure, and can place themselves + link themselves to the goals of the organization. So much for knowledge management, in such a simple form!

In these process-orientation days, I have found organization charts more and more disfunctional. What do you get?

- Powerstructure/reportingstructure
- Functional area's and departments (but often functional departments support multiple processes, and only parts of it)
- Names of people

The thing is - the basic question: "What does this company do" is not easy to answer. For a process-oriented person (like me :-)), that is often difficult - I want to see the chain of actions that lead to results for customers, and their interrelation + the people responsible for the different elements in the chain. Stuff that not easily can extracted from the organization chart.


So - can we come up with a new standard? The processchart, procesogram? Some high-level, I understand this in 1 minute, easy to draw and maintain diagram?

That quickly answers:
- External stakeholders
- Key transactions
- Chains of actions/process areas that support and fullfill transactions
- Key people responsible for parts in the chain, chain accountability

I challenge the reader - do you know something like this??

Some of my thoughts:
- The dutch "Demo" method (http://www.demo.nl/) offers a very concise diagram (organisation construction diagram) - however, this misses the accountability structure.
- In the method of Cordys - there is a business model

Curious if other people have a better diagram technique!
