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.
Jeff Bezos and Root Cause Analysis
unrelated update:
I’m always impressed when CEO’s demonstrate Deming-like behavior as they lead; it’s rare, but there’s almost a magical, mobilizing, and inspiring force that happens when CEO’s or corporate leaders behave in a respectful, inspiring, common-sense, and thoughtful way.
Today, I’m reminded of an experience back in 2004 while I worked for Amazon.com — something Jeff Bezos did that I still carry with me to this day.
Maintain Forward Tension
One principle in Wing Chun is the maintaining of forward tension. To explain, I’ll draw the distinction between Tension and Energy and show how this principle in Wing Chun can be applied to Change Management.
Tension is a type of Energy
A Wing Chun maxim goes as follows:
soft and relaxed strength will put your opponent in jeopardy
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.
Do Not Run From Your Customers
I’ve spoken extensively about the unheralded — but, arguably, the most important — Pillar of The Toyota Production System: Respect for People. Today, I want to highlight an interesting company that appears to have done an amazing job at Participative Management and in eliminating fear and mediocrity in the workplace: Semco Group.
I was first made aware of Semco Group after watching this amazing video on the MIT website. I sought to learn more about Semco and found some pretty amazing case studies such as the following:
We Remember Experiences, Not Features

“people remember experiences, not features or attributes” – a.g. lafley
I love companies and products that are disruptive, simple, and yet elegantly meets an unarticulated but dire customer need.

Tell us a little about yourself: education, background, and career focus.
Necessary but Insufficient
Motorola (MOT), the inventor of Six Sigma, is in big trouble. Even though it invented Six Sigma, this is a clear example that shows how Lean or Six Sigma are not a cure-all for corporate woes, but that good leadership and a winning strategy are key in a competitive world — Lean or Six Sigma is necessary, but not sufficient.
