In my first post in this series, I mentioned that Minitab reached out to our customers who are practitioners of quality improvement to better understand how they complete projects, what tools they use, and the challenges they come across in achieving quality initiatives. One area they said they…

I know the CEO of a group of large companies who is a big believer in small, continuous improvements—primarily through ideas from employees on how to improve their own work or processes. This group also has Six Sigma experts, some of whom privately believed that small improvements weren’t worth…
A few days ago we received an email from a friend at a machine shop. He had just finished a process capability analysis for a critical feature (a runout on a cylindrical part) and was shocked by the output. The spreadsheet software he used showed him a process capability (Cpk) of 0.39 (see figure…
Quality Transformation With David Schwinn
I just finished participating in a delightful design charrette. I’m sharing this with you because design can be a very powerful tool in the Six Sigma arsenal, and this little charrette both reminded me of and taught me a few important lessons about the design process.

Quality Transformation With David Schwinn
Story update 12/06/2013: Wow did we mess up. When this story originally published we, the editors, introduced an error into the story regarding the Alaskan oil spill (which the author hadn't mentioned in his original) and didn't realize it. When readers pointed out the error we compounded the…

Capability statistics are wonderful things. They tell you how well your process is meeting the specifications that you have. But there are so many capability statistics that it’s worth taking some time to understand how they’re useful together.
Two capability statistics that are hard to keep…

In part one and part two of this series, I've outlined some reasons why a lean Six Sigma project might have been deemed a failure. We’ve gathered many of these reasons from surveying and talking with our customers. I'd like to present a few more reasons and then share some advice from Minitab…

In the lean Six Sigma framework, we normally define what is called the critical-to-quality (CTQ) characteristics. A CTQ characteristic is any feature or product that is important to the customer. However, in the FUSE framework, which stands for formulate, understand, synthesize, and execute, we…

In part one, I discussed how to avoid a lean Six Sigma project failure, specifically if the reason behind the failure is that the project solution never gets implemented. Now let’s discuss a few other project roadblocks that prevent teams from completing projects and some suggestions for…

Many managers ask me, “How can I accelerate my company’s lean transformation?” My answer is twofold: First get the direction right, and then get everyone rowing in that direction.
One of my columns on this topic from about three years ago (worth reading for context if you don’t remember it),…

Defects can cause a lot of pain to your customer. They can also cause a lot of pain inside your body.
The picture below shows my broken right clavicle. Ouch! You might think of it as the defective output from my bicycling process, which needs improvement.
Sitting around all summer cinched up in…

Arecent call with an old colleague from Europe got me wondering about a question that few are conscious of: Who is the customer of your quality document? Oh boy, did we have an interesting discussion about quality systems.
My friend was developing and reinvigorating his employer’s quality system,…

Before my first book, Maximizing Lean Six Sigma (West Bow Press, 2013), was published, I’d begun work on a second book, which details a new approach to lean Six Sigma called FUSE—for formulate, understand, synthesize, and execute. It’s an approach that enables organizations to maximize enterprise…
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…
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…
