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.

Not Accountable, Not Responsible
Team size can make a big difference in the success of your service or product. What is counterintuitive for most people is that the larger the team size, the lower the likelihood of success for your service or product. Why? Entropy can set in and large teams are inherently bad vehicles for communication. More insipid, however, is that the larger the team, there is a higher likelihood of accountability and responsibility being diffused across the team.

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.

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.

Black Holes and Supply Chains
It’s critically important in any transaction to be able to answer the question “where’s my stuff” or “where are we in the process?” This requirement is often referred to as Traceability and Visibility; sometimes, people refer to this overall process as Click-to-Ship.

Takt Time and Dumber-by-the-Minute
I remember a very humbling experience of thinking that I knew how to solve problems and being shown just the opposite by an hourly associate. That was during my internship while I was in graduate school; I was haughty, boasting that I came from a top university and demonstrating in my thoughts and body language other prideful nonsense. I’ve learned that you can learn something from anybody. I’d like to think that I’ve become wiser since then and have changed my behavior to reflect that experience.
