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…

I have discussed the economics of project management numerous times in presentations all over the country, and based on the response to my message, I have to conclude that many people just don’t get it.
Let me again sound the wake-up call with a quote from V. S. Liebhold, co-author of the article…

Some commonly held ideas about skewed probability models are incorrect. These incorrect ideas are one source of complexity and confusion regarding the analysis of data. By examining the basic properties of skewed distributions this article can help you to greater clarity of thought and may even…

This month’s column was prompted by an especially thoughtful commencement address by Michael Ward, reproduced in the May/June 2015 issue of Imprimis (Hillsdale College). Ward, of course, encouraged the students to strive for success, but interestingly predicted that failure is inevitable and is to…

If you’ve read the first two parts of this tale, you know it started when I published a post that involved transforming data for capability analysis. When an astute reader asked why Minitab didn‘t seem to transform the data outside of the capability analysis, it revealed an oversight that…
