I think this is the insight underlying Tokyo's zoning system (linked here a few weeks back) that keeps the city so eclectic and alive, and Toyota's production system that seemingly no one can replicate though its been studied for decades, with support from Toyota.

It seems to me that in Toyota, a first, basic process is designed centrally by someone who is an authority in that specific area, but realizing that the top of the pyramid lacks the on the ground information necessary for continuous improvement, it pushes agency to change the process down to the bottom of the pyramid, to the people who make up the process.

That is how Toyota is able to evolve their process and achieve yearly gains in efficiency of around 10%. There's no great genius other than in the insight that the boss can't do the job of his subordinates, that knowledge is situational.

And that is probably why companies fail to adapt the TPS - because they do not trust and even despise people on the floor.
