December was a busy month for everyone at GBMP. In addition to all of the usual activities to close out the year, we were packing to relocate from Newton, Massachusetts, to our new office in Boston. We were also tossing a whole lot of stuff, something we’d previously neglected to do.
As promoters…

Why do we waste our time and effort completing checklist after checklist for tasks that we can complete even when half awake? Do we not have better things to do than complete checklists?
Good question! And the answer is simple: If there is a checklist, it exists for a reason, and we need to follow…

Due dates. Whether it’s building a house or implementing an enterprise quality management software (QMS) solution, everyone has them, everyone wants them. What does home construction have to do with going live with a new QMS solution? There are actually quite a few similarities.
Create realistic…

Happy New Year one and all! For our first QDL of 2019, we were pleased to present some thought-provoking content on the benefits of compromise, the dangers of rhetorical trickery, and the meaning of Chekhov’s gun. Let’s take a closer look:
Ripped from the headlines Can’t anyone here get along?…

One of my favorite things to do when I learn new and interesting information is to apply it to a different area to see if I can gain further insight. Here, I am looking at the principle, “Chekhov’s gun,” named after the famous Russian author, Anton Chekhov (1860–1904), and how it relates to gemba…

We tied up last year in a neat little bow, talking about how stories define ourselves and our work; waste is waste, no matter your political leanings; and putting numbers from the news in context.
“The Gift of Being Small” This article by Quality Digest’s Taran March wonderfully illustrates how we…

The control chart is at the heart of the very definition of quality. It is central to building, maintaining, and predicting quality into the future. However, control charts today, more often than not, are misused and misunderstood. The aim of this article is to show not only how control charts are…

As the global economy grows, it’s more necessary than ever to stay on top of efficiency. Keep up with increasing production demands by implementing a continuous improvement method to streamline the workflow.
Continuous improvement is an ongoing effort to improve products, services, and processes.…

Last week I joined the New England Idea Generation Consortium (NEIGC) on a tour of the Stone Zoo where we had the opportunity to see how continuous improvement is expressed in an animal-care function.
In the open area for black bears, Senior Keeper Dayle Sullivan-Taylor explained to us the…

Iam not really sure how it started, but one day a couple months ago, I found myself diving down an internet rabbit hole in search of more information on a guy named Alfred Adler. Adler was an Austrian psychotherapist in the early 1900s who, although a good friend of Sigmund Freud, developed a…

Everybody wants to design and conduct a great experiment! To find enlightenment by the discovery of the big red X and perhaps a few smaller pink x’s along the way. Thoughtful selection of the best experiment factors, the right levels, the most efficient design, the best plan for randomization, and…

In this article I will show that the conventional method for calculating uncertainty is not always reliable. In fact, it is generally only exact when the measurement can be represented by a simple linear equation and the input uncertainties are all normally distributed. Whenever the measurement is…

Walter Shewhart, father of statistical process control and creator of the control chart, put a premium on the time order sequence of data. Since many statistics and graphs are unaffected by this, you might wonder what the fuss is about. Read on to see why.
Figure 1 shows a series of measurements…

Even though most businesses have invested in quality management and performance improvement, each organization is unique. People, processes, and machines must be coordinated to achieve desired outcomes. This is not easy.
Whether you’re in discrete manufacturing, a process industry, or a service…

The frequently referenced learning pyramid asserts than an average student retains 75 percent of information learned through practice, compared to just 5 percent of what he hears in a lecture. Although experts may dispute the relevance of these figures when applied to modern society, all of us can…

Next to defining a problem accurately, root cause analysis is one of the most important elements of problem-solving in quality management. That’s because if you’re not aiming at the right target, you’ll never be able to eliminate the real problem that’s hurting quality.
So which type of root cause…

Process validation is vital to the success of companies that manufacture pharmaceutical drugs, vaccines, test kits, and a variety of other biological products for people and animals. According to FDA guidelines, process validation is “the collection and evaluation of data, from the process design…

Perhaps the reader recognizes d2 as slang for “designated driver,” but quality professionals will recognize it as a control chart constant used to estimate short-term variation of a process. The basic formula shown below is widely used in control charting for estimating the short-term variation…

Our industry embodies many aspects, but “Big Q” quality generally involves issues affecting management, measurement, and methodologies. This week on QDL, we covered all of them, and more. Let’s look closer:
“Ripped from the Headlines: Tariff Fallout” U.S. manufacturers are currently dealing with…

In this episode we look at a history of quality, how you serve your customer in the housing industry, and what makes a good review.
“Young couples ‘trapped in car dependency’”
Building entry-level housing along highways may give couples the chance to buy a home, but at what cost to them and the…

During the late 1990s, I was working in the Silicon Valley for a medical device company, responsible for a drug-infusion pump manufacturing operation. I had just completed a crazy period where I had also “temporarily” (months and months...) led the advanced engineering department after that manager…

I am writing today about “bootstrap kaizen.” This is something I have been thinking about for a while. Wikipedia describes bootstrapping as “a self-starting process that is supposed to proceed without external input.” The term was developed from a 19th-century figure of speech—“pull oneself over a…

If you are a CEO of a manufacturing company with many value streams, it’s impractical to think that you have the time to review all the performance measures of every value stream in your company. Yet you need to know the operational impact of lean on your entire organization.
The traditional…

It is all too common in the industry: A part design is created and sent out for production only to hit repeated snags as questions arise about datums, locators, symbols, and values. Even simple misunderstandings, such as where the geometric dimensioning and tolerancing (GD&T) lines terminate,…

Have you heard this? “Just because this department is a bit dingy—and it’s sometimes harder than heck to get the scoop on things—doesn’t mean it’s a bad place. Good work happens here. In fact, we’ve been doing darn good work in this area long before you showed up with a bucket of hope called…
