A young man in PQ Systems' hometown survived a dramatic auto accident last summer in which police-captured video footage of his spectacular, airborne vehicle was broadcast throughout the nation. That was just the beginning of his problems, for during his hospitalization, his medical records were…

After my last column citing some really bizarre flaws in how our brains perceive reality, I thought I might cover some flaws in logic that are applicable in the world of quality. So, basically, even if our brains are working correctly, we can still send our Black Belts off on false trails trying…
The emergence of cargo cults on some Pacific Islands after World War II is an amusing and oft-repeated story.
The relatively simple lifestyles of these islanders were interrupted by Japanese aircraft dropping large supplies of clothing, medicine, canned food, and tents to support the Japanese…

I got one of those mass e-mails the other day, the ones with inspirational stories promising good luck and eternal salvation, provided you forward it to 10 people immediately. I chose to delete it and take my chances with the Almighty, betting that He was not really a party to an agreement linking…

A colleague, friend, and lean leader in health care related a story awhile back that I think is worth sharing. Joanne Marqusee, COO at Hallmark Healthcare System, was standing in line at a grocery store checkout. While she waited, Joanne recalls, she noticed that the cashier had added an unusual…

Measurement error is ubiquitous. As a result, over the past 250 years, different areas of science and engineering have come up with many different ways to deal with the problem. One approach to the problem of measurement error was developed during the 1960s within General Motors. Throughout the…

A couple years ago, I was consulting in a large rolling mill to help reduce late deliveries to its customers. After walking the floor for the first time with an enthusiastic 20-something engineer (let’s call him Mark), I asked for help with observation at a particular point in the factory where…
A new year always brings new hope, new plans, and new perspectives. While looking ahead is the most direct route to progress, looking back is essential to understanding the present. After all, the past creates the consequences that will shape the future.
With this in mind, the editors of…

A friend recently returned from a visit to China; his company had been acquired by a Chinese organization and he had gone there as part of the mutual due diligence. Not only did he come back impressed by their lower manufacturing costs but also with their technological advancements. While we in…

In my July column, “Where Do Manufacturing Specifications Come From?” we found that the intraclass correlation coefficient is the natural measure of relative utility. This measure is theoretically sound and easy to explain. This column will look at how to use the intraclass correlation to…

Signs in factories or on the back of long-range trucking rigs sometimes proclaim “X days since our last accident” or “No on-the-job injuries since 1964.” Extending the stretch between such accidents may be motivated by this announcement alone, but there are better ways to diminish or prevent…

You know what the third-quarter review meeting means: a packet will be handed out with bar graphs and, no doubt, trend lines on each of about a zillion “key performance indicators” that show:
• This month vs. last month vs. 12 months ago (maybe year-to-date as well)
• The three months’…

I know we have been talking about statistics a lot in my last few articles, but recent reader comments have prompted me to think more about why doing statistics properly matters. Come with me, dear reader, on a journey to find out why you should embrace, and not run screaming from, your inner…

Last year I discussed the problems of transforming data prior to analysis (see my August 2009 column, “Do You Have Leptokurtophobia?,” my September 2009 column, “Transforming the Data Can Be Fatal to Your Analysis,” and my October 2009 column,“Avoiding Statistical Jabberwocky.”) There I…

People can make plenty of mistakes when launching a lean enterprise transformation. Interestingly, many of these mistakes are similar if not identical to those made by entrepreneurs when starting a business. Perhaps these mistakes are generic enough to be widely applicable and not specific to lean…

Sometimes it’s interesting to watch trends develop from the relatively safe perch of business media. A press release from Aveta Business Institute last week drew my attention because it wasn’t doing what 99.9 percent of all press releases do: selling something. Instead of announcing a new product,…

As my quest for knowledge and understanding of the real world continues, I decided to meet with an old professor of mine. I can remember almost every professor I ever had boasting about mentoring former students, so I figured my professor would be delighted to help me out. I am smart, hardworking…

Throughout the last couple of articles, I have explained and illustrated that understanding the random sampling distribution (RSD) of a statistic is key to understanding the entire basis of inferential statistics. Which is just a fancy way of saying “avoiding career-terminating decisions.” This…

I recently experienced the pain associated with coaching a team with poor chemistry. It happened within a kaizen event team, so the pain was finite, being that a kaizen event is a rapid improvement of a limited process area. It was, however, an opportunity to learn a few team-formulation lessons,…
