Bull Wranglers
There are more than 1,100 textbooks referring to “short-term process capability,” as distinct from “long term.” Surely 1,100 textbooks can’t be wrong? Let’s apply the first Bull Wrangler test. Does short- and long-term process capability make common sense?
What is capability?
According to ISO…

One of the recurring sentiments I hear from business executives is that lean Six Sigma (LSS) simply takes too long to implement. Without senior management buy-in, implementing it is not only difficult, it’s also nearly impossible. What if there were an easier way that resulted in faster…

On March 28, 2013, the world lost a person whom many consider to be a major contributor to the world of industrial statistics: George E. P. Box. Relatively unknown outside the world of statistics, Box was certainly very well known by those who have studied or practiced industrial statistics.
His…

What’s wrong with root cause analysis? Let’s begin with the name, which is singular. It implies that there is only one root cause, when in reality most problems are usually caused by a complex combination of several factors, some of which are more significant than others.
To appreciate this point…

During the past 20 years, lean Six Sigma (LSS) has proven itself as an effective strategy for business success in virtually every industry sector. The methodology has helped organizations realize their processes are the engines that drive operational excellence and customer value. Recently,…

Statistician to the Stars William Briggs deserves credit for his correct prediction of the Best Picture Oscar the day before the ceremonies this year. Although Briggs would never encourage anyone to misuse his model this way, I feel my statistics heartstrings strummed by the desire to remind…

Last weekend I decided to change the oil and tune up my classic car, a 1972 Datsun 1200. (My wife has other names for it.) It sports a “four on the floor” and a simple four-cylinder engine that doesn’t even need fancy smog controls. Since I hadn’t tinkered with this car in a long while, I was…

There are many different process control methods and procedures available to the quality practitioner. A popular but problematic visual technique employs the traffic light analogy.
As discussed in the article, “Stoplight Charts With SPC Inside,” by Steven Prevette (Quality Progress, 2004), the…

One of the most challenging issues I hear from people within the lean Six Sigma community is how to ensure that a lean Six Sigma project is sustainable. If your lean Six Sigma project is highly dependent on top leadership support to keep it going, there’s a risk of losing the focus and support when…

It’s your first day at the Jedi Temple, working as a lightsaber manufacturer. Your first task on the job is to run a capability analysis on the length of lightsabers being produced. Your main concern is to see if the lightsabers fit within the required length specifications set forth by the Jedi…

Allow me to introduce you to FUSE, a value-based lean Six Sigma model that enables organizations to maximize enterprise performance with the least friction. FUSE embodies three core Chinese concepts of trust (shin), relationships (gunaxi), and knowledge (zhi), or more specifically, reflective…

Ron Behrens, an old friend and colleague, recently replied to my invitation to share examples of the intelligent use of statistics, such as that used in our Six Sigma projects. I asked for stories, some data, and some statistical analyses. With his response, he noted that I had probably already…

In lean Six Sigma, the concept of voice of the customer (VOC) is paramount. VOC takes into account the customer’s wants and needs. But I believe this concept falls short in taking into account the wants, needs, and concerns of all aspects of an enterprise. We may not get the support we need to be…

The three value concepts of my new lean Six Sigma model are based on the Chinese terms shin, gunaxi, and zhi. The third term, zhi, means to know or understand. Confucius believed that for most people, learning was ongoing. One of the philosophies of Confucianism is that everything a person learns…

Six Sigma was originally created by Bob Gavin at Motorola during the 1980s; however, it could be argued that a comparable methodology was in use as early as the 1850s. Florence Nightingale is known for founding the field of nursing, but few people outside of the field of mathematics appreciate her…

Last week I visited with JVS, a terrific Boston-area organization whose mission is “to empower individuals from diverse communities to find employment and build careers, and to partner with employers to hire, develop, and retain productive workforces.”

It’s no secret that in the world of statistics, the individuals chart and X-bar chart are pretty much the popular kids in school. But have you ever met their cousin EWMA? He’s all about exponentially weighted moving averages (EWMA). That’s him in the middle of the class, wearing the clothes that…

At the heart of the Toyota Way are two pillars, continuous improvement and respect for people. These are supported by five values: challenge, improvement (kaizen), seeing for yourself (genchi genbutsu), respect, and teamwork. The word “challenge” means either a tangible thing, such as competition…

In our world of excess everything, savvy innovators realize that less is actually best. They know that delivering a memorable and meaningful experience hinges on user engagement, which is best achieved through a subtractive approach. Anything excessive, confusing, or wasteful is intelligently and…

Isee the same cycle in so many places. What cycle? A five-step process for ensuring that ideas fail.
Step 1: Altruistic leaders encourage suggestions and ask associates for their continuous improvement ideas in an attempt to foment some daily kaizen. Step 2: Associates (not all of them), somewhat…
Anthony Burns’ opinion piece, “Six Sigma Psychology” published in the Oct. 25, 2012, edition of Quality Digest Daily, piqued my interest. I read it in anticipation of discovering a candy house waiting at the end of a long dark path, along with suggestions about how to avoid the oven. Perhaps I’d…

It may seem dangerous to ask questions, especially in an environment that is hostile to change. The heart of improvement often lies in listening to many viewpoints in order to involve people affected by the outcome. In an environment of trust, it’s okay to disagree with the boss. W. Edwards Deming…

A report of how a process performs is not only a function of process characteristics and sampling chance differences. It can also depend on sampling approach. For example, one person could describe a process as out of control, which would lead to activities that address process perturbations as…

I have seen organizational lean or lean Six Sigma job requirements stating that any level of certification from almost any institution is acceptable, at least according to the recruiter. But guess what? Taking a four-hour online course on lean, lean Six Sigma, or any other quality management…
