I seem to be drawing a lot of pyramids lately. This one was drawn to help give some focus to a discussion about introducing a brand new function into an organisational unit. There was a lot of discussion around requirements at different levels of capability maturity. I drew a basic pyramid on the board as a way of focusing our minds as to what are the fundamentals and how they relate to the high levels of maturity (essentially repurposing a hierarchy of needs). I then sat down and my colleagues used the pyramid as a framework to guide and document their discussions.
I like using the pyramid as its simple, easy to understand and also lends itself to breaking out (see the badly drawn left hand side of the photo) into a roadmap.
