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.

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.

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 incomplete solutions.

As our new year unfolds, I wanted to write an article to remind myself of three pieces of advice. They are from Epictetus (55–135 AD), Marcus Aurelius (121–180 AD), and George Pólya (1887–1985). Epictetus and Aurelius are two famous Stoic philosophers of the past, and Pólya is a famous Hungarian mathematician.

The Forth Bridge is a famous railroad bridge in Scotland and is more than 125 years old. It needs painting to fend off rust. Albert Cherns, the late famous social scientist who founded the Department of Social Sciences at Loughborough University, identified the Forth Bridge principle as part of the nine principles for designing a sociotechnical system. He also referred to this as “the principle of incompletion.”
