In the Six Sigma world, we give a lot of lip service to the importance of the customer; we even have an official name for it—voice of the customer, or VOC. The problem is that many businesses don’t really have a good system for giving the customer what they ask for, much less one for listening to…

When organizations decide to deploy a Six Sigma initiative, there are several foundation stones required for a successful venture. One of those building blocks is leadership. From executive-level support to assigning champions and choosing the right projects, leadership is critical for Six Sigma…

I read an article in Wired magazine the other day that got me to thinking about the relationship between statistics, engineering knowledge, and theory. The article claimed that with the era of massive data storage and analytical capabilities, the scientific concept of the “theory” was becoming…

I was working with a client to create their business’s critical performance measures the other day, and one of the managers said, “We should set the target higher than we want it—you know, aim high to hit low.” This set off one of my rants, and I thought I would share it with you.
When I worked as…
We examined the practices and major problems that can easily occur in the use of balanced scorecards in the June 3 issue of InsideSixSigma. Now let’s look at why attention to causal event analyses can improve the future performance of any process. Often, this traditional method fails to make metric…

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…

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…

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…

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…

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…
