Your organisation as a node

There's a book that states you should think of yourself as a node - the link between one person and another.

It would be impossible to do illustrate an individual as a node, but it might be possible to describe an organisation in this way - how it can link things together.

So we had a stab at doing it. It's a work in progress and about my company as it's the organisation we know best.

Has anyone done anything similar for their organisation?
Is this useful?
Is this a clear way or describing the links or is there a better way?
