At the base of the pyramid is human reflex — i.e. response to a stimuli. One level above it is problem solving which in her mind doesn’t require creativity and just a set of processes that can be activated. Above that is creativity — an elevated form of problem solving that involves invention and improvisation. And at the very top is imagination, which Patti insisted is “boundless creativity.” You can mix the different levels at the interfaces and see a different kind of creativity/action happening. I sincerely enjoyed how this model felt in my mind. -JM
