The Source of Dirt
In Amazon’s 2008 letter to shareholders, Jeff Bezos shares about a Kaizen event he participated in:
At a fulfillment center recently, one of our Kaizen experts asked me, “I’m in favor of a clean fulfillment center, but why are you cleaning? Why don’t you eliminate the source of dirt?”
I’ve spoken numerous times about Bezos on Lean Thinking, some of which are here, here, here and here but there are many more — just browse shmula.

Fast Food Congestion
Every system has constraints — sometimes several — minor bottlenecks and major bottlenecks. What makes managing constraints even more challenging is that bottlenecks move: up-and-down the process paths.
I saw this phenomenon recently during a visit to a fast food restaurant, which I discuss in this post — but, my application of the Theory of Constraints, Lean Manufacturing, and Six Sigma as applied to a Restaurant can be applied to any Dynamic System.
