PC once again left a provocative post in the Lean Thinker’s Community, and gave us a link to this Tim Harford TED talk that drives home the point that learning and improvement is more about rapidly discovering things that don’t work than about designing things that do.
Tom Wujec makes the same point in the Marshmallow Challenge. In that video, Tom talks about how 5 year old kids out perform most adult groups in a problem solving / learning game. While the adults engage in a single cycle of “know-build-fail” the kids engage in multiple cycles of “try-fail-learn-try again.” In the improvement world, we call this process PDCA.
Harford’s key point is that learning only happens through a process of trial of large numbers of ideas, followed by the selection and further trials on the best ones.
Hmmm… that sounds a lot like the 3P process of “Seven Ideas” as well as “Set Based Design.”
