The image above is only a small slice (2 of 15 pages) of the overall model.

This is a re-drawing of Bruce Archer’s 229-step design process; which is difficult to come by. It also brings together Archer’s descriptive text with the diagram for the first time.

    I really like the visual feel to this. Still trying to fully understand how it works — a example to go along with it would be good.

    Love this! Is there a lecture or paper somewhere that explains the diagram so that I can understand with reduced friction how it works?
