Lean Math With Mark Hamel
The time observation form, also known as a process study form, is a basic and often-used tool for lean practitioners. Note that here we are talking about applying the continuous time-observation method and not the work-sampling method.
The form, in combination with a stopwatch, serves multiple…

Measurement system analysis of uncertainty is one topic in lean Six Sigma training that is too often ignored or under-taught. I believe that it is under-taught because most instructors have never used or understood it. Therefore, this column will dive deep into what it is and why you should learn…

How many of you have been through a lean Six Sigma (LSS) project or business transformation and there was no internal conflict between employees or among managers? My guess is very few. In any LSS project, company transformation, or change initiative there are going to be instances of love and war…

ometimes it’s necessary for a person to offer up views that seem to be an affront. Because these views often challenge the status quo, people’s reactions can be mixed. Some will consider the person a heretic for expressing them, and others will wonder why anyone would say such a thing. The…
Lean Math With Mark Hamel
Work content (Wc) represents total operator cycle time or, if multiple operators are involved, the sum of operator cycle times to perform a specific process(es) or subprocess(es). The scope of human work, including both value-added and nonvalue-added activities, may encompass a complete value…

Maersk Line is the largest container shipping company in the world. At any given time, its 500 vessels transport approximately 3 percent of the world's gross national product (GNP). In 2007, I walked into Maersk as a lean Six Sigma consultant looking for business and walked out with a job.
I saw…

To promote ethical and moral responsibility in shaping its graduates, the Rose-Hulman Institute of Technology created a sustainability initiative to reduce its own environmental footprint.
As part of that team’s efforts, Six Sigma students at Rose-Hulman conducted a project to reduce food waste…

During the past dozen years, companies I have worked with have, between them, completed more than 1,000 lean Six Sigma (LSS) projects. Based on this experience, I’ve found that improvement projects can be broadly categorized into three types: quality-improvement, revenue-enhancing, and cost-saving…

For me, a quality professional with 20 years experience in manufacturing—producing everything from garbage bags to luxury ski boats—my transition to the service industry was a shocking experience to say the least. It was not without challenges, I must confess.
When I was asked to join the…

All processes are affected by various sources of variations over time. Products that are designed based on optimal settings will, in reality, tend to drift away from their ideal settings during the manufacturing process.
Environmental fluctuations and process variability often cause major quality…

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…
Quality Digest
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,…

Chances are you are not fully satisfied with the results of your lean initiatives. It’s also likely that lean thinking is not used to improve your employees’ skills in working together. That’s because you are using only half, probably less, of the power of lean thinking.
In 2001, Toyota declared…

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…

Got your attention by what seems a bizarre claim? Yes, you can significantly reduce the number of procedures you maintain by converting your ISO 9001 quality management system (QMS) to one that is also certified to the medical device standard ISO 13485 and the aerospace standard AS9100.
I am…

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…
