“If you are too obsessed with success, you will forget to live. If you have learned only how to be a success, your life has probably been wasted.” —Thomas Merton, Love and Living
Sometimes there are dots just waiting to be connected....
I was rather surprised when Pope Francis mentioned Thomas…

I work with companies that are serious about being lean organizations. Most of them use lean accounting. It’s not about changing your accounting system. It’s about embracing lean principles and methods. Lean changes the way people look at management accounting. Here are 10 things to think about.…

My wife Mary has an obsession—she always checks the expiration and freshness dates on food products that we purchase. Mary also marks purchase dates on products such as ketchup, mustard, and salad dressings when she places these items in our refrigerator. I think she has an expiration date on me…

Although information is readily available about applying team-building techniques to Six Sigma projects, there’s not much about how learning styles affect the success of Six Sigma teams. Knowing that the “people side” of an otherwise technical and statistical-based methodology is important to a…

Finally... the new version of ISO 9001:2015 has been released. I can hear many of you screaming, “Hurray!” Or not. More realistically, I’m sure many of you living in the kaizen world are thinking, “Yeah, so what? This stuff has nothing to do with real kaizen, and in fact, it often creates…

During the early days, late 1970s to late 1980s, there existed just a few small organizations to help people learn about and implement Toyota’s production system (TPS). They were led by people with decades of hand-on practice at Toyota and its affiliated companies. Some organizations, however,…

As a sort of character-building exercise, I recently opened an unsolicited email from my health insurance provider. I was intent on doing a quick purge of sham, spam, and flimflam, and I figured this one would be no different. But I also know I’m biased against health insurers, so I decided to set…

I gave a rather successful talk on communicating design of experiments (DoE) at the recent ENBIS 14 conference in Linz, Austria. Things went mostly well, but it’s also fair to say many attendees had one major criticism: I didn’t explain why one factor at a time testing (OFAT) isn’t ideal. That…

There are many ways to improve your thinking skills. One way is by practicing critical thinking. Teachers require their students, from elementary school on through college and graduate school, to do research to gather information, analyze the validity of data, determine the strengths and…

The adage “if you aren’t moving forward, you’re falling behind” is true more often than not. Regardless of the type of business, all organizations need to improve to survive. The last words uttered by managers in failing organizations are, “We’ve always done it this way.”
The key to long-term…

The best analysis is the simplest analysis that provides the needed insight. Of course this requires enough knowledge to strike a balance between the needed simplicity and unnecessary complexity. In parts one and two of this series we looked at the properties of Weibull and gamma probability…

I can tell you all about the California coast, its cultural and economic dynamics, my favorite hideaway beaches and eateries, and I can attest to the wisdom of never turning your back to the surf. I know these things because I've lived in The Golden State most of my life, but I'…

I mean it! If your company can’t master 5S, try “1S” and stop! Stop the entire lean transformation until 5S is mastered in at least one process-focused area of the facility.
It’s a tremendous waste for a company to spend thousands, if not millions, of dollars on a “lean transformation” only to…

As a person working in quality manufacturing, it’s probably in your DNA to look at a quality challenge and choose Six Sigma or something similar as the framework for getting to the answer. It’s also likely that you’re spending a lot of time gathering and analyzing data, applying hypothesis…

This article describes a novel approach to calculating the financial aspect of overall equipment effectiveness (OEE), with the result referred to as $EE (as in monetary units). By using $EE, a management team readily can “SEE” their operation in financial terms. Employees are then better able to…

When we take pictures with a digital camera or smartphone, what the device really does is capture information in the form of binary code. At the most basic level, our precious photos are really just a bunch of 1s and 0s, but if we were to look at them that way, they'd be pretty unexciting.
In its…

Of all the tools in the lean toolkit, 5S is the one that has proven to be the most effective—and also the most elusive. It’s effective because the actions needed to sort, set in order, shine, standardize, and sustain mirror the deeper, critically important philosophy of thinking about value, waste…

Story update 9/8/2015: There was an error in the data set for columns "Skew" and "Kurt" in figure 7. The error has been corrected.
Clear thinking and simplicity of analysis require concise, clear, and correct notions about probability models and how to use them. Last month in part one we looked…

You’ve heard of Bam Bam, Duran Duran, Zsa Zsa, so-so, tutu, and Reverend Tutu. And now we have... Gemba Gemba! But what is Gemba Gemba?
Quite simply, Gemba Gemba means going to the gemba for the purpose of observing others going to the gemba to ask, teach, learn, coach, and challenge. In this way…

As both a participant and witness to the practice of lean management in higher education, I’d like to point out methodological errors in relation to how lean is practiced in industry.
People in industry who practice lean management correctly provide us with a standard to which we can compare the…

I recently had a dream in which Adrian Bass, a colleague and friend for whom I have much admiration, asked me why I still care about quality management after all these years.
You can substitute Six Sigma for quality management because, in my mind, they are both part of a larger belief system that…

Just, please, plot the data if you have gathered some time-to-failure data, or you have the breakdown dates for a piece of equipment. Any data really. It could be your review of your car maintenance records and notes and dates of repairs. You may have some data from field returns. You have a group…

Statisticians say the darnedest things. At least, that’s how it can seem if you’re not well-versed in statistics.
When I began studying statistics, I approached it as a language. I quickly noticed that, compared to other disciplines, statistics has some unique problems with terminology. These are…

Quality and Six Sigma are often considered as links in a chain. For example, when quality is poor, many times the immediate response is, “Let’s improve it using Six Sigma.” But does Six Sigma, or any other program for that matter, really improve quality? Or, are they simply mirrors to let us know…

Just 100 years ago, very few statistical tools were available and the field was largely unknown. Since then, there has been an explosion in available tools, as well as ever-increasing awareness and use of statistics.
Although most readers of this column are looking to pick up new tools or improve…
