‘From laughing tots in Haitian preschools to inner-city gang members to top executives in global corporations, people everywhere are gathering in circles. These circles are generating trusting relationships among people with long histories of antagonism; promoting healing among people suffering…

In the years since ISO 9001 and ISO 14001 were first published, many organizations have followed the models of these standards in designing their own management systems. However, many of those systems haven’t been utilized to effectively manage risk. Many have been minimally developed to meet…

I have evolved to using fewer, simpler tools in my consulting and have never been more effective, as I commented upon in my last column. It made me ponder the relevance of much of what I learned in my master’s statistics program. Thinking of the most basic concepts, I decided to look up what the…
The purpose of this article is to point out a problem when using percentages for subgroups over time, or for members in a larger group, where the size of the denominator varies and probabilities are being estimated. Also to introduce a solution: adjusted p-chart scores (APC), a new way to score or…

ISO 9001 continues to wend its way through the revision process, and as it does so there have been lots of discussions and prognostications over the impending changes. All the wringing of hands and ongoing debate will not hurry the process or change the outcome.
The standard is still on track to…

If you’re not a statistician, looking through statistical output can sometimes make you feel a like you’ve wandered into Alice in Wonderland. Suddenly, you find yourself in a fantastical world where strange and mysterious phantasms appear out of nowhere. For example, consider the T and P in your t…

Whenever the original data pile up against a barrier or a boundary value, the histogram tends to be skewed and non-normal in shape. Last month in part one we found that this doesn’t appreciably affect the performance of process behavior charts for location. This month we look at how skewed data…

This is the last in a series about how lean manufacturing has affected the people and the companywide culture at Hytrol Conveyors, a designer and manufacturer of advanced conveyor systems. As described in part 1 and part 2, dozens of interviews were conducted with a wide range of employees at the…

When my mother looked at the prices of new hats, studied their features, and then went home and tried to remodel her old hat with feathers or lace to look like those fancier models, I saw the value of doing things yourself—for my mother, an attitude perhaps shaped by her own parents and their…

I really can’t make this stuff up.
I wrote a post a couple of years ago titled: “How to Talk to Your Kids About... Quality Improvement,” in which I lamented about Community Hero Day in my daughter’s first-grade class and the need to explain to her why I wasn’t at the “community-hero level” of…

I've been presenting at the Institute for Healthcare Improvement (IHI) annual forum for 21 consecutive years. Maybe the biggest surprise from these two decades has been the awesome power of simply "plotting the dots," i.e., plotting important organizational data in their naturally occurring time…

The title of this article is a search term that recently hit The Lean Thinker site. It’s an interesting question—and interesting that it gets asked.
“Kaizen” is now an English word—it’s in the OED—and defined as such: “Noun. A Japanese business philosophy of continuous improvement of working…

There are many tools available for investigating quality problems. One useful and easy-to-use set of statistical tools is John W. Tukey’s exploratory data analysis (EDA), which quality engineers can use for generating hypotheses. Tukey’s EDA provides many different methods for looking at data, and…

Should an organization’s design engineers step foot on the production floor, or would this be too much of a distraction from what they get paid to do—cranking out new designs? For most progressive and forward-looking organizations, this is a no-brainer. Of course product engineers would be, and…

On a recent vacation, I was unsuccessfully trying to reunite with my family outside a busy shopping mall and starting to get a little stressed. I was on a crowded sidewalk, in a busy city known for crime, and it was raining. I thought there was no way things could get more aggravating when…

In November 2014, Quality Digest Daily published the first in a series about companywide lean cultures and how a lean journey affects people and companies. Jonesboro, Arkansas-based Hytrol Conveyors, a designer and manufacturer of advanced conveyor systems, allowed an in-depth examination of why…

Whenever the original data pile up against a barrier or a boundary value, the histogram tends to be skewed and non-normal in shape. In 1967 Irving W. Burr computed the appropriate bias correction factors for non-normal probability models. These bias correction factors allow us to evaluate the…

According to a recent IndustryWeek article, the 2015 edition of ISO 9001, the standard on quality management systems, is nearing completion.
The new version of IOS 9001 will have three areas of focus:
1. The process approach will be strongly emphasized; that is, the quality management system has…

In my last column I wrote about the seven perspectives that pollute customers and culture. These perspectives rule the design of our organizations. They are inherent to our work cultures and thinking. They put us on autopilot as we toil in our everyday work. The first step to change that is to…

My wife, Carole, and I recently participated in the 16th Annual ILA (International Leadership Association) Global Conference. The theme was conscious leadership. At the conference, Meg Wheatley was given a Lifetime Achievement Award. That puts her in the company of Peter Drucker, Warren Bennis,…

During the last year or so I've heard a lot of people asking, "How can I calculate B10 life in Minitab?" Despite my being a statistician and an industrial engineer (mind you, one who's never actually been in the field) and having taken a reliability engineering course, I'd never heard of B10 life…

In late October, longtime Baldrige examiner Miriam Kmetzo traveled to Suzhou, China, to attend and speak at the 6th Quality Forum for Academics and Innovation.
Kmetzo gave a presentation at a session that featured four quality award programs in the international arena: the Malcolm Baldrige…

The ISO 9001 standard is currently under revision. The decision to do so wasn’t driven by one dramatic event happening in the marketplace, but rather by due diligence of the International Organization for Standardization (ISO) committees and working groups that perform systematic reviews of…

When auto manufacturers set out to create award-winning vehicles, much consideration is given to interior sound quality. Ironically, the manufacturers have been so successful in mitigating road noise they have inadvertently caused a new problem for themselves: Apparently, the cars are too quiet.…
