Ihave been thinking a lot lately about innovation and how we may have emphasized one component at the expense of another. Here I’m talking about something that should appear obvious—the focus of innovation in building new things. We are constantly reminded that innovation is about building new…

The world of work shares a single basic transaction, used millions of times a day: translating vital information into human behavior. But operationalizing this formula is not that simple. Workplace information can change quickly and often—schedules, customer requirements, engineering specifications…

Who remembers VisiCalc, often referred to as the first killer app? In 1978, this spreadsheet software ushered in the personal computing boom. Although it only ran on Apple’s priciest computer (the one with massive 32K RAM), its ability to calculate and recalculate arrays had much to do with the…

As companies seek to gain efficiencies in the workplace, provide choice for employees, and attract and retain talent, strategies involving agile working and free-address have gained traction. When our Gensler La Crosse office relocated last year, we leveraged the opportunity to support an agile…

Although automation has been successful in replacing repetitive, simple tasks, the human workforce still plays a critical role in manufacturing. Even the most sophisticated and automated manufacturing operations rely on human operators to configure, run, and properly maintain production equipment…

Does your organization benefit from lessons learned? Does it learn from previous quality issues? A vast amount of learning takes place every day in every manufacturing facility. Do global manufacturing companies share experiences gained from resolving quality issues between overseas plants? And…

I love to cook. When I make good food and share it with others, they will take a bite and look as excited to eat it as I was to create it. They might not understand the subtleties that went into it, but they understand the product. Satisfied eater, satisfied chef.
When we do something and are…

It’s an open secret that many automotive and aerospace manufacturers have unacceptably high defects and costs. And where defects are on the rise, quality costs aren’t far behind.
Even one defect could mean recalling an entire batch, a problem that can cost thousands of dollars per minute if it…

We are here, and it is now. Further than that, all human knowledge is moonshine. —H. L. Mencken
I ran across the term “moonshine shop” while reading about a kaizen blitz at Ontario-based communications firm Cogeco. “Brad, [Cogeco’s] maintenance leader, coordinates all projects relating to modifying…

I have written about sample size calculations many times before. One of the most common questions a statistician is asked is, “How many samples do I need—is a sample size of 30 appropriate?” The appropriate answer to such a question is always, “It depends!”
In today’s column, I have attached a…

I recently got hold of the set of data shown in figure 1. What can be done to analyze and make sense of these 65 data values is the theme of this article. Read on to see what is exceptional about these data, not only statistically speaking.
Figure 1: Example data set.
A good start?

Cogeco’s technical distribution center in Burlington, Ontario, is one of Canada’s drop-off points for internet modem and cable device repair. In 2011, the company’s management carried out a kaizen blitz to improve the efficiency of its device repair process. The process was indeed challenging but…

Business partnerships are nothing new. Partnerships that result in leaner manufacturing processes, more consistent quality, and lower manufacturing costs—that is worth talking about.
With global competition so fierce, manufacturers must always be keen to spot areas of muda (waste). Even seemingly…

Quality is related to processes. A process is “a series of actions or steps taken in order to achieve a particular end.” It doesn’t matter whether the process is the handling of invoices, customers in a bank, the manufacture or assembly of parts, insurance claims, the sick passing through a…

Let’s take a second to emphasize who is important in the following quotes, all by W. Edwards Deming: “If you can’t describe what you are doing as a process, you don’t know what you are doing.” “A bad system will beat a good person every time.” “Drive fear from the workplace.”
Well, by golly, it’s…

Confidence intervals show the range of values we can be fairly, well, confident, that our true value lies in, and they are very important to any quality practitioner. I could be 95-percent confident the volume of a can of soup will be 390–410 ml. I could be 99-percent confident that less than 2…

A lot of people in my classes struggle with conditional probability. Don’t feel alone, though. A lot of people get this (and simple probability, for that matter) wrong. If you read Innumeracy by John Allen Paulos (Hill and Wang, 1989), or The Power of Logical Thinking by Marilyn vos Savant (St.…

Many years ago, the Toyota Production System Support Center (TSSC) introduced a visual measurement device to my factory, referred to as a “production activity log” (PAL), also known to some as an hour-by-hour chart. Posted at the last operation of a particular process, the PAL provided an up-to-the…

Three years ago I wrote an article titled “The Emperor’s New Huddle Boards,” in which I expressed concern about the trappings of improvement without actual improvement. Since then, my concern about the application of leader standard work and gemba walks has deepened as these potentially valuable…

There are many subjects that we cover regularly here at Quality Digest. Chief among these are standards (ISO 9001 or IATF 16949, for example) methodologies (such as lean, Baldrige, or Six Sigma), and test and measurement systems (like laser trackers or micrometers). One topic, however, is…

Process improvers the world over rally around root cause analysis as if it were the holy grail of all things organizational. But is it?
Understanding the root cause of a problem certainly makes sense in the context of a present day situation carrying the potential for a correct answer or solution…

In our May 11, 2018, episode of QDL, we looked at overproducing ideas, bad quotas (aren’t they all), and how anger can help identify core values.
“Questioning Quotas”
When are quotas bad? Most of the time. But here’s a good example.
“How to Find Your Company’s Core Values”
Oddly enough, your…

Last month I joined Eric Buhrens, CEO at Lean Enterprise Institute (LEI), to host a leadership team from Tel Aviv’s Sourasky Medical Center. They were on a study mission to many of Boston’s fine hospitals and were winding up their week with a visit to LEI. Early in the discussion, one of our guests…

Boeing is demanding its suppliers reduce their prices by 10 percent, according to a February 2018 article published in Bloomberg Businessweek. It’s a hard pill for many to swallow, given that that these cuts are on top of the roughly 15-percent cuts demanded in 2012, when the company launched its…

A couple of weeks ago I posed the question, “Are you overproducing improvements?” and compared a typical improvement “blitz” with a large monument machine that produces in large batches.
I’d like to dive a little deeper into some of the paradoxes and implications of 1:1 flow of anything,…
