I have been writing about kaizen a lot recently. It is a simple idea: change for the better. Generally, kaizen stands for small incremental improvements. Here I’m going to look at what is the best kind of kaizen.

In today’s column, I will be looking at kaizen and kaikaku through the lens of the explore/exploit model. Kaizen is often translated from Japanese as “continuous improvement” or “change for better.” Kaikaku, another Japanese term, is translated as “radical change or improvement.” Kakushin is another Japanese word that means “innovation” and is used synonymously with kaikaku.

It’s not easy to find topics to write about, and even if I find good topics, it has to pass my threshold level. As I was meditating on this, I started to think about procrastination and ambiguity. So my column today is about the importance of “fuzzy concepts.” I am using the term in a loose sense and will not go into depth or specifics.

I recently read Jordan Ellenberg’s wonderful book, How Not To Be Wrong: The Power of Mathematical Thinking (Penguin Books, 2014). I found the book to be enlightening and a great read. Ellenberg has the rare combination of being knowledgeable and capable of teaching in a humorous and engaging way. One of the gems in the book is, “Which way you should go depends on where you are.”

Today I will look at epistemology at the gemba. Epistemology is the part of philosophy that deals with the theory of knowledge. It tries to answer the questions, “How do we know things, and what are the limits of our knowledge?” I have been learning about epistemology for a while now, and I find it an enthralling subject.

It’s been a while since I’ve written about statistics. So in this column, I will be looking at the rules of three and five. These are heuristics, or rules of thumb, that can help us out. They are associated with sample sizes.

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).

In today’s column, I will be looking at process validation and the problem of induction. Yesterday, I looked at process validation through another philosophical angle by using the lesson of the Ship of Theseus.

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.
