One slide worth a thousand words...?

I used the slide below in a workshop I ran in London in December on globalisation and large, complex intranets.

A participant in the workshop told me I could run an entire workshop around this single slide.
Sounds like a good idea.

P.S. The three arrows refer to something I believe strongly, having seen hundreds of intranets in as many different organisations.

You need 3 flows of information - top down, bottom up and horizontal.
If one of the three is missing or weak, your intranet (and your organisation) is missing something.
And losing business value.
