Over the years, scorecards have progressed through many changes, good and bad. Although scorecards often evolve into a meet-the-numbers game, regardless of the consequences to an enterprise as a whole, restructuring can produce dramatic improvements for any organization. This results in counter-…

I thought this month we would get away from the stats of the last few columns. Hey, quiet down! How can anybody read over all that cheering?
There’s something missing from most Six Sigma implementations—a gap that, if left unattended, leads to wasted time and money, as well as the failure of the…

Manufacturing firms intent on capturing and distilling rich streams of data will find them. Companies will often look at a capability maturity model (CMM) in rows and columns—a format common across many industries and many applications—in Excel. Most data dumped from a database end up in a grid,…

If you have been following my articles for the last few months, you know that we’re almost done with an experimental analysis and that today we will be doing the final step—making our company money. If you haven’t been following my articles, then you should probably be flogged with a soggy…

Few process improvement topics generate more questions or may be least understood than design of experiments (DOE). This is regrettable as DOE is probably one of the most important activities—after the charter definition—that a manager/Black Belt will be performing during the Six Sigma process.This…

For the last couple of columns, we have been analyzing a simple experiment where we look for the best choice for a new gear material. We have used analysis of variance (ANOVA) to detect a difference in the mean wear for the four different materials. In the last column, we performed a post-hoc…

Six Sigma promoters and innovation advocates have emerged as opposing camps in the battle for tool supremacy in the organization improvement wars. As Business Week said in “Six Sigma: So Yesterday?” and “At 3M, A Struggle Between Efficiency and Creativity,” which described how GE, Home…

In Part 1 of this article I discussed Six Sigma failures and the fundamental flaws in the term Six Sigma, as seen in figure 1 below, which highlights the flaws in the hundreds of Six Sigma web sites displaying the nonsense of out-of-control processes that are the result of the claimed “unavoidable…

Last month, I described a simple problem to determine which gear material resulted in longer wear. We reviewed the extremely powerful technique called Analysis of Variance (ANOVA) and found a statistically significant and important effect on the average wear due to gear material. I also…

Six Sigma captured the imagination of CEOs around the world. There have been many claims of its successes yet these have at least partially been attributed to the Hawthorne Effect, which implies that if enough money is thrown into any methodology, at least some short-term results can reasonably be…

By the time you are reading this, you will have made your New Year’s resolutions, and I will have already broken mine. But I have an idea for a resolution that you might be interested in keeping, and one that could make your New Year happy and profitable. It is something that most Black Belts I…

With all the emphasis today on quality, and studies showing that quality is very important to the leaders of American business, why are so many organizations struggling to achieve and sustain quality systems? The answer is that managers have been inundated for 20 years with a parade of quality…

Editor’s note:This short story is part of a three-volume series—Integrated Enterprise Excellence: Going Beyond Lean Six Sigma and the Balanced Scorecard, by Forrest Breyfogle. Within the context of this fictional story the author discusses the attributes of an integrated training program that he…

As I’m writing this, our first big snowfall of the year is piling up outside and it is –10°C (15°F). This brings to mind the many times my grandfather told me of how he walked to school in winter uphill (both ways) with no shoes. So I wondered, will I be able to spin the same yarn for my girls and…

Imagine you decide to learn a new language and never make a mistake while learning it. No typos, no misspellings, no grammatical errors, everything turns out perfect. The first reaction is, “How can this happen?” Perfection isn’t believable. Similarly, if everything one tries doesn’t work, usually…

Harvest time—vegetables fresh from the local farmer’s market going right into a homemade soup, eaten with fresh bread. Yum! This month, I’d like to talk about a recipe for a Greek alphabet soup, which you had better know about if you plan on doing an experiment. This may be the first recipe that…

Between 1987 and 1992, the most successful implementation of Six Sigma didn’t require Black Belts or Green Belts. Instead, Six Sigma initiates received training in problem solving, team work, basic quality tools, and statistical tools. However, sense of urgency, dramatic improvement, and teamwork…

I seem to be thinking about the measurement phase a lot recently. I suppose it’s because I’ve seen some teams working hard on problems that turned out to be nothing more than problems with measurement. Let me give you an example.Once upon a time, I was responsible for a product that was frequently…

Six Sigma is being implemented at more and more corporations. After a significant investment in training, corporations initiate projects. Six Sigma Champions have told me that some companies have several thousand projects in the pipeline. Managing that many projects is a major task. How many…

For quite some time a major question has been cropping up in my mind: Is Six Sigma’s application in software development as effective as it is in the manufacturing industry?The answer is “No.” The savings and benefits that occur in the software industry due to Six Sigma and other process-…

There is something that will get you into trouble if you don’t know about it, and which in my experience very few Black Belts or even Master Black Belts know about. It’s only in the mind of the person doing the research, and no software program will know about it. This mysterious property is “…

As I teach Six Sigma in my classes, I try to create projects for myself, and often it’s the same project over and over. This time, my project was to use Six Sigma to reduce my extra weight.In 1986 one of my clients distributed a “heart for life” goodie bag on Christmas. In the bag was a measuring…

I spent my June and July articles beating up on the “sigma” index commonly associated with Six Sigma (and continue to do so over in my discussion board.) Let me sum up by saying that, while not wrong, “sigma” isn’t an efficient metric for accomplishing what we are trying to do in today’s business…
