There is a great Greek paradox/puzzle called the Ship of Theseus. There are multiple versions and derivations to it. My favorite version is as follows (highly watered down). Theseus bought a new ship. Each day he replaced one part of the ship.…

Entropy in the Manufacturing World Complexity lies between low entropy and high entropy

Mon, 04/10/2017 - 12:02

In this article, I will be looking at entropy in the manufacturing world. Entropy is generally defined as a measure of disorder. This general definition can sometimes be inadequate. Let’s look at the example of a desk in an office. One could say…

The Incomplete Solution Somewhere between wrong and useful

Wed, 02/22/2017 - 12:03

The world of systems is very wide and deep, and this column can’t be perfect and all-encompassing. My goal here is to emphasize that solutions based on incomplete models lead to incomplete solutions. I’m not calling them incorrect solutions, just…

Wed, 09/28/2016 - 14:19

Kaizen is often translated as “continuous improvement” and identified as one of the core themes in lean. Today I’m pondering the question: Can kaizen ever be bad for an organization? In order to go deeper on this question, first we have to define…

Uncertainty is all around us. A lean leader’s main purpose is to develop people so they can tackle uncertainty. There are two ways to tackle uncertainty: One is genchi genbutsu (go and see, or seeing for yourself), and the other is to employ the…
