You know how sometimes you think everyone knows a secret that they haven’t let you in on? Well, I had the opposite happen to me the other day. I assumed everyone knew the purpose for measurement system analysis (MSA), a.k.a. gauge repeatability and reproducibility; but I found out that a number of…

Kaj Ahlmann (right), owner of the Six Sigma Ranch, Vineyards, and Winery, and vineyard manager, David Weiss, create great wines by applying old-world techniques and the rigor of proven quality improvement.
Some people take it easy when they retire. But Kaj…

I have just finished rereading Walter A. Shewhart's 1939 book Statistical Method from the Viewpoint of Quality Control (Dover Publications, 1986). Mine is the 1986 edition, which has a foreword by W. Edwards Deming. Shewhart, a Bell Labs man, pioneered quality control and was a major inspiration…

Sometimes when studying something that has become too familiar to us, we can gain valuable new insights by looking at it from a radically different perspective. Much has been written, for example, about how important customer service is for business—so much, in fact, that it becomes easy to lose…

Last week I had occasion to view once again, in the company of a client, the excellent little video, “Toast Kaizen,” produced by the Greater Boston Manufacturing Partnership (GBMP)1, and narrated by Bruce Hamilton. In that video, Hamilton takes a simple everyday process, that of making toast, and…

A common error of many Six Sigma and operations research professionals is not properly selecting the correct subgroup sampling technique when constructing a statistical process control (SPC) chart. Incorrect subgroup sampling technique selection has become worse in the modern computing age,…

Here at Quality Digest, we get a lot of mail: Some of it’s critical, some of it’s praiseworthy, some of it’s cantankerous, and some of it’s challenging. All of it is insightful. And then, every once in awhile, something comes along that simply... well...
The following was sent to us from a…

I have identified myself as a “reformed” lean Six Sigma Master Black Belt. Some will see this as an affront to lean and Six Sigma. I want to assure you that there are many things to like about lean and Six Sigma. The issue at hand is that a better solution is available that can help organizations…

Lean, lean Six Sigma, total quality management (TQM), and other techniques have helped companies improve processes through the execution of projects. However, much of these efforts have resulted in siloed process improvements that don't benefit the enterprise as a whole.
To illustrate this…

I was flipping through some Japanese books on sayings and speeches given by Taiichi Ohno looking for inspiration for a new article when I found the following passage:
“Within the Toyota Production System, a lack of ability to do kaizen becomes a critical flaw. Does this mean that if you do…

If you are buying two or three complex assemblies per month from a contract manufacturer, it would be reasonable to check every one carefully; there’s a lot that could go wrong. However, if you are buying 100,000 simple subassemblies per month it makes no sense for you to 100-percent check them…

I became aware of a truth about lean problem solving and kaizen yesterday while reading an article about 10 internet rules and laws, “Internet rules and laws: the top 10, from Godwin to Poe,” published on the Daily Telegraph’s web site (www.telegraph.co.uk).
4. Skitt’s Law…

n the past there was only one criterion required to be a good supplier: you had to ship very few nonconforming items. If your proportion of nonconforming items took a turn for the worse then you would be “in trouble,” and you would stay in trouble until your fraction nonconforming dropped…

ix Sigma and lean provide tools for process improvement. Most of today’s business improvement programs can trace their roots back to a lean or a Six Sigma heritage. In general, these process improvement methodologies are considered advances from total quality management (TQM) and other methods…

The financials of an enterprise are a result of the integration and interaction of its processes, not of individual procedures in isolation. Using a whole-system perspective, one realizes that the output of a system is a function of its weakest link or constraint. If you're not careful, you can be…

At the 2009 National Association for Healthcare Quality conference, I gave a speech on lean Six Sigma simplified. At the end of the session, one of the attendees asked, "If Six Sigma is so easy, why isn’t everyone doing it?" My answer: Because we’ve made it too complicated, expensive, and hard…

Story update 10/22/2009: We added a reference to Toyota Kata in the first paragraph.
The tools and techniques of what is commonly called “lean manufacturing” have their origin in the Toyota Production System (TPS). While the lean movement deserves much credit for popularizing these tools and…

I'm not saying that the following apply to you... really. But, you might be a Black Belt if...
You test your co-workers for normality – and find some of them to be non-normal and a little skewed…
…and you know you can handle non-normal co-workers if you can just transform them
You recall…
In 2005, according to a BBC News report at the time, operating rooms all over the United Kingdom were thrown into chaos and operations canceled due to broken, missing, or dirty surgical instruments. The Royal College of Surgeons called for a national audit of decontamination units, following a…

Regular readers of my column know that I abhor surveys that don’t provide some type of incentive or discount on a future purchase for completing the survey. I realize that I may have discussed this subject ad nauseam, but have you noticed that every store, restaurant, gas station, doctor’s office…

n his inauguration speech, President Obama called for improving health care quality and reducing costs. In 2008, U.S. health care costs exceeded $2.4 trillion and are expected to climb to $3.1 trillion by 2012, according to the National Coalition on Health Care.
Of these costs, 25 percent…

n emergency response organization differs substantially from our usual public health organization for day-to-day business. However, as the spring 2009 H1N1 (also referred to as swine flu) outbreak highlighted, usual public health processes are fundamental for effectively responding to a…

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.
The articles following…

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…
