In the past two months we have looked at how three-sigma limits work with skewed data. This column finds the power functions for the probability limits of phase two charts with skewed probability models, and compares the trade-offs made by three-sigma limits with the trade-offs made by the…

A few years ago, I was asked to conduct a workshop, deliver a keynote, and chair a three-day conference on manufacturing process excellence in Europe, produced by the Process Excellence Network (PEX), a division of IQPC. Although that was a lot to ask of me, the lineup of speakers and content was…

You’ve set aside Sunday afternoon to bake some cookies, but you discover you have run out of eggs. Your partner in marital bliss has gone out and taken the car. You call a couple of mates, and they tell you to try bananas, vegetable oil, or applesauce as egg substitutes. You decide to have some fun…

Today I’m looking at design from a cybernetics viewpoint. My inspirations come from cybernetics and design theorists Ross Ashby, Stafford Beer, Klaus Krippendorff, Paul Pangaro, and Ranulph Glanville. I was curious about how the interface of a device conveys the message to the user on how to…

I have been immersed in the lean world for more than a quarter century. From the start, when some folks from the Association for Manufacturing Excellence showed me how quick changeover could save my injection-molding operation (and probably my job) from imminent destruction, to now, when I can…

The idea of doing the little things consistently over time is a powerful one that we often overlook in our hurry to show a spectacular result this week. We don’t get results from the big action we are taking today. We get results when business-as-usual is getting the little things right the vast…

How would you like to go hands-free, maintain visual focus, and save time? These are just some of the benefits of using voice command to control machinery. Increasingly sophisticated natural language processing, based on artificial intelligence, also means that it is becoming possible to issue…

Several years ago, I was asked to address a startup meeting at a new client, a large manufacturer of medical devices. The company was resource-rich, but after several years of trying had not yet gained significant traction with its lean efforts.
There were perhaps 40 people in the room, half from…

Editor’s note: Read episode two in the Respect for People series here.
I was standing in a back room of the Honolulu Museum of Art that was off limits to the public. In this one room, protected from bugs, humidity, and light, was the world’s largest collection of Japanese woodblock prints. (My…

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:
The first factor represents variability and is…

More often than not, an effective implementation of operator-led visuality produces a 15- to 30-percent increase in productivity on the cell or departmental level, beginning with the implementation of the “visual where” (or, as our trainers like to call it, 5S on steroids). But that effectiveness…

Reflecting on Douglas McGregor’s X and Y theories of human motivation, Shigeo Shingo took the position that each of us by nature has a dual tendency: sometimes lazy and self-interested, and other times motivated and generous. Which of these behaviors dominates is directly related to the environment…

A daisy rising from my brick walkway reminded me this morning, that even in the worst environment, there is a chance for growth. But this kind of individual heroism does not portend success for lean transformation. As an organization with the slogan “Everybody Everyday,” GBMP places high value on…

Pickleball is arguably the fastest-growing sport in the United States, especially among baby-boomer retirees. This game is similar to tennis, but is played on a smaller court (44 ft × 20 ft) with a solid paddle and a perforated polymer ball much like a wiffle ball.
Pickleball’s popularity may be…

Responsibility. It’s a hard word to come to grips with. What is the responsible thing to do right now? What is my personal responsibility? What is my responsibility as a team, family, company, state, or country member? What do I expect from others?
The world now is in transition, from being…

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), and Economic Control of Quality of Manufactured…

In a general sense, capability is the ability to do something. Within manufacturing, capability is given a much more specific definition. It is an expression of the accuracy of a process or equipment, in proportion to the required accuracy.
This can be applied to production processes, in which…

Whatever the process or type of data collected, all data display variation. This is also true in software development. Any measure or parameter of interest to our business will vary from time period to time period, e.g., number of incidents per week or month, time taken in resolving incidents,…

If I have been on a decades-long drive to make work more flexible, Alton Brown has been on a similar one in the kitchen. There is no shortage of rants on his various shows about “unitaskers”... things in your kitchen that can only do one thing and therefore are only useful in a few, often unlikely…

In everyday language, “in control” and “under control” are synonymous with “in specification.” Requirements have been met. Things are OK. No trouble.
“Out of control,” on the other hand, is synonymous with “out of specification.” Requirements have not been met. Things are not OK. Trouble.
Using…

‘Why are our changeovers taking so long?”
If you’ve asked this question on the shop floor, more than likely you were met with blank stares by your employees. Open-ended questions like this are overwhelming, so employees try to find quick answers that don’t really address the problem. They don’t…

During the early 1980s, GM, Ford, and Chrysler established the Automotive Industry Action Group (AIAG), a not-for-profit organization with the mission “To improve its members’ competitiveness through a cooperative effort of North American vehicle manufacturers and their suppliers.” In the late…

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 phenomenon.”
A problem statement is a model of the…

As some of you already know, I was in Ford Motor Co.’s corporate quality office during the early 1980s when, just after “If Japan Can, Why Can’t We” aired on NBC, we pleaded with W. Edwards Deming to help us out of a very bad place. One of the things I most remember about those times was that he…

My favorite part of a recent podcast with James Clear, author of Atomic Habits (Avery, 2018), was the last five minutes, when he talked about a potential downside of good habits. When we decide to improve and create a new practice with the right cues and rewards, we form a new habit. But habits can…
