I love a good process diagram…. its not just a pretty picture – the content and the form need to complement and build on each other. They are tricky things to design.
I did this one recently, and to be honest it needs more thought. The steps shown are all at different scales so its not perfect but it does manage to get 3 independent iterative cycles positioned within a larger iterative cycle.
This one is a much better view of the “Deliver” Cycle, with better entry and exit points. I also like the floating assets and people bits that complement the process itself.
This one focuses on the describing the different scales of time in cyclical activities. Who said you cant mix a flat process diagram with a 3D desk and people !
And lastly, well the sketchy nature and purple makes it look straight up crazy (there is a bit of “Magic Happens” to it) – so i like it 🙂
the architecture of everything 
I would say the most important thing to remember when trying to design these things is to check to see if it actually reflects what happens.

Jason, enjoyed this post (and many others of yours!). I’m wondering if you could point me to a good resource for a tutorial on how to create illustrations similar to those you did here (in illustrator, fireworks, etc.).
Thanks!
