This is the final column in the debate between Donald Wheeler and Forrest Breyfogle on whether or not to transform data prior to analysis. Because the debate started with Wheeler's article "Do You Have Leptokurtophobia?" we are letting him have the last word on the topic.

To Chris Collins, lean and Six Sigma, just like government and business management, go hand in hand.
In Erie County, where he fiercely advocates that a lean government can and will save taxpayers millions of dollars, Chris Collins became the first county executive in the nation to implement lean…
While I have been saying this for decades, and while K’ung Fu-tzu implied it millennia ago when he called for a balance of knowledge and action, it takes a while to sink in. W. Edwards Deming showed how simply taking a pencil with paper and plotting the data makes action possible. Experts in data…

It was the great W. Edwards Deming who first applied this tenet, “Drive out fear,” to quality management in his book Out of the Crisis (Massachusetts Institute of Technology, 1982) It’s one of his 14 Points for Management.

Aviation safety is a very critical issue. For millions of people to fly safely every day around the world, a very large and complex network of business and regulatory agencies have to operate flawlessly, delivering defect-free, on-time parts and hardware to all corners of the globe.

A previous article of mine in this newsletter, “NOT Transforming the Data Can Be Fatal to Your Analysis,” addressed the need for appropriate transformations and a predictive performance measurement system.
The statistical business performance charting (SBPC) methodology that was described in…

We have all had to plan a trip to the airport. Sometimes it goes well and sometimes not so well. One of the problems we have is dealing with the variation in the trip time to the airport. Since I travel to the airport a lot and like analyzing data, I keep track of my travel time to the airport.…

If you have been following my articles over the last few months, you have seen that even though statistical process control (SPC) charts are very powerful tools for examining a process, it turns out that there are a lot of ways to mess up SPC. This month, I am going to finish up with a few more…

Story update 9/23/09: Reference to 9.5.2.f was changed to 8.5.2.f in second paragraph.
As more suppliers are required by their regulators and customers to achieve ISO 9001 certification, and because certification symbolizes a point of competitive differentiation in a tight economy, emphasis on…

Is the theory of constraints compatible with lean thinking and can the two approaches be used together? This article looks at some of the similarities and differences between the two approaches and suggests how they might be coupled to advantage.

Not surprisingly, there was controversy over Forrest Breyfogle's article, "Non-normal Data: To Transform or Not to Transform," written in response to Donald Wheeler’s article "Do You Have Leptokurtophobia?" Wheeler continued the debate with "Transforming the Data Can Be Fatal to Your Analysis."…

“Writing is not a job; it’s a hobby!” thundered my father when I told him my plans for college. “You need to get a profession: Medicine, law, engineering, or accounting.”
I cheerlessly acquiesced and enrolled in a pre-med program, but at the end of my first year, after struggling through…

Wireless communications have well and truly arrived in the industrial arena and considerable effort is now being put into integration and the writing of standards. In this article, the author considers the many benefits and a few drawbacks of this cost effective technology.

The ISO 9001 standard’s requirements with regard to suppliers are very short and concise but carry a lot of punch. These requirements can be very deceiving and in fact are often misinterpreted and carried out poorly or partially. By implementing the clause correctly, an organization will get the…

Following my article on Leptokurtophobics (Do You Have Leptokurtophobia?) it was almost inevitable that we should hear from one. We were fortunate to have someone as articulate as Forrest Breyfogle III to write the response. However, rather than offering a critique of the points raised in my…

Five things to lean my company? In two days? That's pretty quick. Why so quickly?
I can think of two reasons. First, people expect things to be done better and faster each day; and it appears we’re getting decent at doing just that. Lean has made huge strides toward contributing to that “…

The band “Chicago” sang those words about "time" decades ago. The second line “Does anybody really care?” seems to sum up what is still in vogue today, especially in the workplace. Just as with vacations where workers are reluctant to leave for fear that someone will discover that their job is…

The final draft of the revised ISO 9004 standard is out for ballot. This means that it will hopefully be available before the end of this year. It’s radically different from the last version. For one thing, the title has changed. It’s now: “Managing for the sustained success of an organization—A…

Even after many years of hearing the words ISO 9000 and seeing many organizations achieve registration to ISO 9001, there are still companies who are skeptical when it comes to going for ISO 9001 registration. For some, a misconception about the objectives of the ISO 9001 standard or a lack of…

Over the past couple of articles, we have explored how an incomplete understanding of how SPC limits are calculated can lead to constructing control charts that look strange. But using some of the things I mentioned, hopefully you can see that these “strange” control charts actually reveal quite…
