f you’ve been to Starbucks lately, you probably noticed the fast-paced employees working their java magic as they take orders from customers in line, not at the register, so that baristas can start the order, and sometimes finish it, before the customer even pays for it.
Yes, I’m all for…

The symptoms of leptokurtophobia are (1) routinely asking if your data are normally distributed and (2) transforming your data to make them appear to be less leptokurtic and more “mound shaped.” If you have exhibited either of these symptoms then you need to read this article.
The origins of…

World War III has begun. This time it’s not a war of battleships, bullets and bombs—this is an economic war. The weapons are televisions, steel, cars, and clothes. This is a war where we have no allies. Every nation is out to capture more of its share of the U.S. and world’s market. We are being…

Pick up any article or book, attend any conference on Six Sigma, or talk with any Black Belt or Master Black Belt and you will hear the Six Sigma gospel about the importance of the voice of the customer. For example, in their book Six Sigma: The Breakthrough Management Strategy Revolutionizing the…

Today I received a sales call from a person interested in becoming a certified Six Sigma Black Belt. He had what I call a "can't do" personality. This is the diametric opposite of the "can do" person. This type of individual looks for reasons why a particular thing can't be done. How about a…

Do you hear Six Sigma professionals express frustration that the organization does not support their efforts?
Are there department heads in your life who have complained that their Six Sigma professionals are not delivering the needed results? And that each project is too time-consuming?…

In a recent post on the Evolving Excellence blog, Bill Waddell tackles one of my pet peeves: activity-based costing, or ABC. Few things do more harm to lean Six Sigma than this method of accounting. In fact, it is my opinion that the accounting systems used by U.S. businesses are responsible for a…

Just the other week, I had the privilege of visiting with three or four companies that were doing lean process improvement. In every visit, each company invited me into their “war room” where they took great pride in showing me their process and value-stream maps and the other trappings of their…

Have you ever met people who “do” statistical process control (SPC) only to get some screwy-looking control chart, and then text: OMG I H8 SPC! (If you don’t understand that, ask your nine-year-old child or grandchild.)
Last month we saw how it is not a failure of SPC, but rather an EBKAC (…

When someone mentions design for Six Sigma (DFSS), the initial thought usually turns to developing new, innovative products. While DFSS has its roots in product development, individual components of the toolset can be applied in a variety of ways.
Recently, the use of DFSS has exploded in…

It is widely known among quality and process improvement practitioners that the lack of a clearly defined scope or charter is perhaps the leading cause for projects not getting started or completed on time and within budget. What are other causes? From my experience, the No. 2 cause for restarting…

Analytic statistical methods are in very strong contrast with what is normally taught in most statistics textbooks, which describe the problem as one of “accepting” or “rejecting” hypotheses. In the real world of quality improvement, we must look for…

In “The Power of Observation—Part 1,” we learned that a good portion of problem solving should be devoted to a thorough understanding of what’s going on before any corrective action steps are taken.
In many cases, too much time is spent on proposing various solutions before the problem has been…

Some authors recommend that you have to wait until you have the range chart “in control” before you can compute the limits for the average chart or the X chart. Why this is not true will be the subject of this column.
To illustrate the issues we will once again use the NB10 data. The 100 values are…

I often get assignments at organizations where I am required to take aside a group of people, either within the building facility or off campus, to focus on issues or problems. Typically these groups spend a considerable amount of time to summarize and present a well-defined problem. The next step…

I discovered a wonderful unpublished paper by David and Sarah Kerridge several years ago (Click here to get a pdf). Its influence on my thinking has been nothing short of profound. As…

The most important element in producing a quality product or service is the attitude of the people doing the work—not only the worker—but the attitude of all levels of management. Employee attitude about the product, about the work, about the boss, and about the company will pretty well determine…

A $1 billion annual budget may sound ample, but a few years ago, the costs of services ranging from law enforcement to cleaning county buildings had squeezed the government of Erie County, New York, to its limit. Residents faced a painful choice: raise taxes or slash services. But Chris Collins,…
The emergence of green technology and increased environmental awareness has prompted a paradigm shift in the way companies think about the design of their products. Because robust designs mean creating products to meet customer and societal needs, it is important that all enterprises rethink these…

One of the most useful diagnostic tools for understanding what is going on in a process is the statistical process control chart (SPC). This is also a frequently misunderstood tool, and these misunderstandings lead to misdirected effort during a Six Sigma process, resulting in lost time and money…

Twitter is the latest new thing. Want to follow John McCain or Al Gore throughout their day? Easy. Just sign up to receive their tweets. While their tweets may provide insights, or just entertainment (Ashton Kutcher and 50 Cent also tweet), does Twitter have value for business management?

When I first got into quality, I really hated verifying the effectiveness of actions taken to correct a problem. After all, I was young and inexperienced. All of the people whose actions I was verifying were older, wiser, and more experienced than I was. Who was I to say that their actions were…

Specific techniques for data collection, fundamental to accurate analysis, are sometimes overlooked in the need to see outcomes or trends in data. The lowly check sheet represents a critical tool in effective data collection if it is used correctly.
Because check sheets are such simple tools,…

With several generations of statistical process control (SPC) technology under our belts, it may be time to rethink how we apply SPC in the 21st century. Basic techniques have been practiced since the 1930s. Some companies will soon be able to say, “we’ve been practicing SPC for 100 years.”…
