One of my favorite equations from Factory Physics, by Wallace Hopp and Mark Spearman (Waveland Press, third edition, 2011) is Kingman’s formula, usually represented as “VUT.”
The VUT equation is named after Sir John Kingman, a British mathematician…Wed, 08/14/2019 - 12:03
After reviewing Mark Graban’s wonderful book, Measures of Success (Constancy, 2018), I started rereading Walter Shewhart’s books, Statistical Method From the Viewpoint of Quality Control (Dover reprint 1986, originally edited by W. Edwards. Deming…Tue, 06/18/2019 - 12:02
I must confess up front that the title of this column is misleading. Similar to the Spoon Boy in the movie, The Matrix, I will say, “There is no lean problem or a Six Sigma problem. All these problems are our mental constructs of a perceived…Wed, 05/01/2019 - 12:03
Today I’m looking at Factory Physics and the Toyota Production System (TPS). My main references for the post are the 1977 paper co-authored by ex-Toyota president Fujio Cho and key ideas from Factory Physics (Waveland Press, 2011).
One of my…Thu, 03/21/2019 - 12:03
Today I’m looking at the profound phrase of Canadian philosopher and a media theorist Marshall McLuhan, “The medium is the message.”
McLuhan noted that: “Each medium, independent of the content it mediates, has its own intrinsic effects, which are…Tue, 02/05/2019 - 12:03
The TV show The Walking Dead, about survival in a post-apocalyptic zombie world, is one of the top-rated currently. I’ve written previously about the show, but today I want to briefly look at the complex adaptive systems (CAS) in the show’s plot…Thu, 01/03/2019 - 12:03
One of my favorite things to do when I learn new and interesting information is to apply it to a different area to see if I can gain further insight. Here, I am looking at the principle, “Chekhov’s gun,” named after the famous Russian author, Anton…Wed, 10/24/2018 - 12:02
I am writing today about “bootstrap kaizen.” This is something I have been thinking about for a while. Wikipedia describes bootstrapping as “a self-starting process that is supposed to proceed without external input.” The term was developed from a…Tue, 10/02/2018 - 12:03
I am a quality manager by profession. Thus, I think about quality a lot. How would one define “quality?” A simple view of quality is “conformance to requirements.” This simplistic view of quality lacks the complexity that it should have. It assumes…Mon, 08/27/2018 - 12:03
I came across an interesting phrase recently. I was reading Kozo Saito’s paper, “Hitozukuri and Monozukuri,” and I saw the phrase “kufu eyes.” Kufu is a Japanese word that means “to seek a way out of a dilemma.” This is very well explained in…
