Some folks like to use control charts to analyze gauge study results. When using a control chart in this manner, one can assume that the chart should represent a series of gauge studies conducted over a period of time. In this example, let’s say that each morning a gauge is verified by recording…

Recent department store sales figures in the Wall Street Journal are interesting and intriguing.

I had a lot of feedback from interested readers in regards to Stupid Six Sigma Tricks #5, which I jokingly called “Pop Stars Without Clothing,” and which was about the frequent misuse of statistics in the Six Sigma world. Taking heart from this response to what might have been viewed as dusty old…

On December 29, 2006, passengers of American Airlines’ Flight 1348 were confined in a parked aircraft for eight hours. By this time, “The toilets on the American Airlines jet were overflowing. There was no water to be found and no food except for a box of pretzel bags.” This fiasco was…

More than 13 hours per week creating documents and nearly seven hours per week organizing documents are common among small and midsize engineer-to-order (ETO) manufacturers; four hours per week are spent managing document routing and another 10 hours per week searching for information. All this…

Last month, I talked about vision vs. video and brought up the possibility of confusion between inspection and measurement. Some think that inspection is qualitative and measurement is quantitative. I can’t say I’ll put the matter to rest, but I’ll present a few different…

How do we conclude that a nagging, recurring blip has become serious enough to justify taking action? How do we assess the significance of anomalies—isolated occurrences and scattered, seemingly unrelated events? Can we objectively distinguish those factors that suggest an escalating…
In a previous column, we discussed the importance of the IECQ quality assessment systems for electronic components, a certification scheme of the International Electrotechnical Commission. The IECQ mission is to provide a business-to-business quality certification scheme that serves industry by…

Last year I had the good fortune of doing some consulting with B&C Specialty Products in Hopeulikit, Georgia. B&C does light manufacturing, primarily plastic molding and assembly, and they also distribute imported products produced by companies in the Far East. They have about…
For the last Brain Teaser, in an interesting spin, sample size was defined as a time window. A is the correct response. The underlying data type falls into the category of defect counts (complaints) within a constant area of opportunity (one hour). These data, of course, follow the…

Businesses have lately been focusing on profit and process improvement. However, profit improvement at any cost to make the upcoming quarter look bright has a price. It appears that most improvement effort leads with efficiency measured by head-count reduction. Improvement shouldn’t be measured by…

We are more than halfway through the countdown of our exploration of the kooky, and expensive, mistakes people make in implementing Six Sigma, and I want to talk about something that’s so fundamental people rarely see it—Stupid Six Sigma Trick #4: Overusing DMAIC.
DMAIC stands for define the…
A certain company has a complaint department that answers calls for three unique products. Because of failure rates inherent to each product type, some products have a higher expected complaint rate than others. Calls are tallied each hour and categorized by product type…

Dairy plants are among the heaviest users of municipal water in the United States, using two gallons of water for every gallon of consumer product produced.
