Recently, in one of the many online discussion groups about quality, Six Sigma, and lean, this question was posed: “Can X-bar R and X-bar S be used interchangeably based on samples size (n) if the subgroup size is greater than one and less than eight?” Answers varied, of course.
In some of these…

Recently, Mary Doyle Keefe passed away at the age of 92. You may not recognize her name, but you’ll definitely recognize her face. Keefe was the model for Norman Rockwell’s famous 1943 painting, Rosie the Riveter.
During the 1940s, various versions of the painting symbolized the contributions of…

If it didn’t work then, will it work now? Elephant syndrome is what I call it, the tendency to never forget. But I’m not referring to a good memory; I’m talking about a faulty forgetter.
Like the elephant in the photo, we remain tied with string to obstacles we could readily overcome. That…

While the computations for a process behavior chart are completely general and very robust, the secret to using a process behavior chart effectively lies in the art of rational sampling and rational subgrouping. Rational subgrouping has to do with organizing your data so that the chart will answer…

Overall, lean is the toolbox we should all be using to help eliminate waste—the stuff you don’t want to do, and the stuff your customer’s don’t want to pay for. The best way to eliminate waste is to communicate what it is and what it isn’t.
One of the key elements in the ISO 9001 standard has…

One of our major problems with healthcare reform is that we are doing it from the top down.
At the top, a bloated bureaucracy works in an environmental context of regulations and finance that seems to be focused on what is best for government and payers. The perils of out-of-control costs have…

The final draft international standard (FDIS) of ISO 9001:2015 will be released in July, and the revised standard is slated for publication in September. Per Annex SL of the “Consolidated ISO Supplement,” some elements of the standard will be restructured to allow for easier integration of…

Generally speaking, I have a problem with authority. I don’t like being told what to do or how to do it. I’m not proud of that.
I recall debating with my high school trigonometry teacher regarding the value of the homework “process”—specifically in those situations where the student in question…

If you are in a leadership role, chances are you believe it’s better to give than to receive. This means you also probably believe you should always be competent, never make mistakes, and always be strong. You may also feel that you should only receive when you have something to give in return.…

In an era when every square foot and extra minute along a supply chain mean dollars saved or squandered, it’s not surprising that auto dealerships have been facing uncomfortable scrutiny. Protected by franchise laws, these icons of American commerce struggle to justify their value to customers as…

Ah, the scientific method. How elegant, how useful—and how easily ignored. The process of studying a problem, formulating a hypothesis, running a controlled experiment, analyzing the resulting data, and then making an objective decision is so quickly cast aside in the interest of quick-and-dirty…

As you browse through lean management pages on the Internet, you may have seen reports on companies having little success with lean, or comments about how misunderstanding lean can lead to bad consequences. From time to time I can sense the level of frustration from those comments, and I…

My career in quality engineering started off at the endoscopy division of Stryker Corp. in San Jose, California. The endoscopy equipment included scopes, cameras, and accessories, and I was in charge of the camera line. Mind you, I didn’t really have much of a clue what this role entailed. I’d…

Earlier this spring, thousands of people from all over the nation gathered in Springfield, IL, to honor the life of our beloved President Abraham Lincoln. After his death in 1865, his body was carried hundreds of miles by a funeral train. It passed through more than a hundred cities, with formal…

I was speaking last week with, Jen, a senior manager at a large manufacturer, and she commented to me, “I know it’s important for me to get to the floor, but the time involved for me and my staff to regularly visit two dozen different departments makes this seem like an impossible task.” She was…

This June will you be wishing the Magna Carta a very happy birthday? An 800-year-old document might not necessarily warrant a lovely slice of cake, but I’m sure someone somewhere will be celebrating this anniversary. No doubt many readers will be wondering why I want to discuss the Magna Carta,…
Gallup
A brand promise is an agreement between a company and its customers. Yet Gallup finds that companies are largely failing to make good on their agreements. Only half of the almost 18 million customers Gallup has surveyed strongly believe that the companies they do business with always deliver on…

Perhaps the biggest mistake business leaders make is to assume that people are resources like any other. The truth is that people are resources unlike any other. At the heart of many business disasters is the misunderstanding that people and man-hours are one and the same.
A close friend of mine…

There is a famous (and often misquoted) line from Samuel Taylor Coleridge’s poem, “The Rime of the Ancient Mariner,” which reads, “Water, water, every where, Nor any drop to drink.”
Odyssey Teams Inc. of Chico, California, is collaborating with the Water Works Program of Pyrmont, Australia, to…

I recently came across the TED Talk by Chimamanda Ngozi Adichie where she discusses the “danger of a single story.” From growing up as a kid in Nigeria to studying in the United States into adulthood, she describes how she and others, having only heard a single story about a certain situation,…

In the past couple of weeks, I have stumbled onto three things that triggered this column. Two of them came from academic-type healthcare journals, one of which shall remain nameless. This type of journal is still trying to make a formal case for improvement. Article after article belabors the…
