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…

There is a lot going on in trade relations between the United States and China recently. Sanctions and threats of sanctions, then sanctions withdrawn. There has also been a great deal of finger pointing and accusations from both sides, all while those most affected by sanctions—you and me—are…

The future of transportation in waterway-rich cities such as Amsterdam, Bangkok, and Venice—where canals run alongside and under bustling streets and bridges—may include autonomous boats that ferry goods and people, helping clear up road congestion.
Researchers from MIT’s Computer Science and…

During the June 1, 2018, episode of QDL, we presented a special look at the parameters of relations between the United States and China, from the shifting perspectives of culture, trade, and history. Dirk and I, along with Quality Digest CEO Jeff Dewar, offered up our thoughts on what it all means…

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.…

Iran across the book, Successful Human Relations: Principles and practice in business, in the home, in government (Harpercollins, 1952) while browsing older books about relationship development from William J. Reilly, who also wrote The Law of Intelligent Action (Joanna Cotler Books, 1945). His…

Human beings are good at placing roadblocks to success and building plans that can’t be followed. We tend to fall back on our “common sense” or “snap judgement” which often makes us feel like our cavalier decisions were actually thought out. Yet, time and again, we find ourselves in deadline…

I n November 2018, in Versailles, France, representatives from 57 countries are expected to make history. They will vote to dramatically transform the international system that underpins global science and trade. This single action will finally realize scientists’ 150-year dream of a measurement…

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…

The 1962 film, Lawrence of Arabia, won the Oscar for Best Picture at the 35th Academy Awards. Given the current conflicts in the Middle East, I recently watched the four-hour movie to learn more about the cultural history of the area.
Thomas Edward Lawrence (played by Peter O’Toole) was a British…

Some properties of a probability model are hard to describe in practical terms. The explanation for this rests upon the fact that most probability models will have both visible and invisible portions. Understanding how to work with these two portions can help you to avoid becoming a victim of those…

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…

As a leader, which would you rather have from your people: dumb obedience or smart disobedience?
Your answer is probably “neither.” You want smart obedience: people creatively solving problems to get done what you want done. And, if you’re a good leader, most of the time you will have that.
Why…

What a week. On April 30, 2018, there were top-level delegations from two disciplines: In Beijing the Chinese hosted a cabinet-level delegation of U.S. trade representatives; and in Seattle, the ASQ hosted the Sino-U.S. Quality Summit, the first of its global summit series as part of its annual…

Tensions are escalating between China and the United States over trade. The Chinese government has announced retaliatory measures on a range of U.S. products, including cars and some American agriculture products after the United States listed 1,333 Chinese products to be hit by punitive tariffs of…

With the threat of a trade war between China and the United States looming, business relations between Asia and the West have not been this hot a topic since the Japanese Economic Miracle that was birthed shortly after WW II. Today, it is China’s turn on center stage as its soaring economic growth…

In part one of this article, we discussed the origins of the United States and China, and how their relationship began to emerge.
Many people might point to the United States as the ultimate example of a laissez-faire, free market, unfettered capitalist system. Some would also say that China…

In part one we saw that China has made great strides in terms of product quality, notably in the tech sector. But it still has a long way to go in other products. Driven by the growing middle class, who like all middle class buyers want value for their money, and by the Chinese government’s desire…

Without manufacturing, the room where you make dinner would be rather stark and barren. There’d be no pots, no pans, no stoves, no spatulas, no appliances—big or small. There’d be no way to prepare the meals that give you and your family sustenance. With no counter, there wouldn’t even be a place…

Back in the 1950s and 1960s, Japanese products were synonymous with cheaply made. Anyone over the age of 50 probably remembers cheap Japanese transistor radios when they were a kid. We all believed, in the day, that the more transistors a radio had, the better. That wasn’t necessarily true, but try…

In June of 1950, W. Edwards Deming began offering training to the Japanese Union of Scientists and Engineers (JUSE) on the precepts of statistical process control.
At almost exactly the same time, Communist North Korea invaded and nearly overwhelmed their southern neighbors, who were immediately…

In May 2015, Chinese Premier Li Keqiang and his cabinet issued a strategic industrial plan; its title translates to “Made in China 2025.” The plan took more than two and a half years to draft and included the input of 150 experts from the China Academy of Engineering. Made in China 2025 was…

Researchers at the National Institute of Standards and Technology (NIST) have been developing a novel way of measuring laser power. Their device, called the Radiation Pressure Power Meter (RPPM), makes its measurements using the force exerted by the laser light itself.
The NIST team has now fully…

A job safety analysis (JSA) worksheet is almost identical in organization to a job breakdown sheet and standard work, all of which assess a job (or process) on a step-by-step basis. This suggests combining standard work with job safety analysis to support ISO 45001.
The concept can be carried even…

As the 21st century dawned, Germany was known as the “sick man of Europe,” with lower GDP growth and higher unemployment than peer nations such as France, Italy, and the United Kingdom. Today, it is widely admired as one of the world’s strongest economies and the undisputed economic leader of the…
