T he dictum, “purpose of a system is what it does” (POSWID) is famous in cybernetics, attributed to the management cybernetician Stafford Beer.
Beer notes: “A good observer will impute the purpose of the system from its actions and thus from the resultant state.”
Hence the key aphorism and acronym…

Students are told that they need to check their data for normality before doing virtually any data analysis. And today’s software encourages this by automatically providing normal probability plots and lack-of-fit statistics as part of the output. So it’s not surprising that many think this is the…

In 1985, about the time I was discovering there was a better way to produce products, The Natural, a film about an aging baseball player with extraordinary talent, was garnering multiple Academy Awards. This archetype concerning natural “God-given” abilities is common in Western culture—in sports…

At some point, every medical device company will encounter an issue that requires an internal investigation. Whether it’s due to a nonconformance, complaint, CAPA, or an audit issue, you’ll have to conduct a failure or root cause investigation to pinpoint why the issue occurred in order to resolve…

Negotiating a salary increase or a job promotion ranks high on the list of hard conversations to have at work, and it doesn’t get any easier without a plan.
“People think, ‘I’m just going to knock on their door, sit down with them, and noodle around and see where this goes.’ That’s not a plan,”…

Ryan Day1 describes how the rise of independent auto dealers is a “gray swan” event for the automobile industry. This was not only bound to happen, as observed by the author, but also long overdue. The article states, “...current state laws prohibit OEMs from selling new vehicles directly to…

The level of excitement was high in our machine shop as we drew closer to our goal of less than 9-minute changeovers on the BNC lathe. (See Part One of this story for how we got there.) Setup improvements had so far reduced changeover time to 20 minutes, cutting the economic order quantity from…

The world of procurement is often tricky. It involves choosing one appropriate candidate, ultimately benefiting them while rejecting and disadvantaging others.
That said, it isn’t just the businesses picked that will profit from winning the contracts; it’s also their supply chain, their local…

We had been working with the Toyota Production System Support Center (TSSC) for two years to build a model line in our assembly department. As we moved from small batch production to one-by-one, the results had been astounding: Customer lead time reduced from two weeks to one day, crew size cut in…

In 2010, new to the world of statistical process control (SPC), I was intrigued by Don Wheeler’s statement that “No data have meaning apart from their context” (from his book, Understanding Variation—The Key to Managing Chaos, SPC Press, 2000, available on Amazon). For a while, I didn’t really get…

As the world moves toward a new, post-pandemic normal, industries must leverage digital transformation at an accelerated pace. This is already happening. According to IBM, 67 percent of manufacturers have accelerated digital projects since Covid-19.
Although improved operational efficiency is…

Every February, there are welcome reminders that spring is on the way. The first for me is a witch hazel bush in my front yard that defies subfreezing weather to produce fragrant yellow flowers. Then, a few weeks later, crocuses and winter aconites will emerge from the snow. The cycle continues…

Last month we looked at analyzing observational data. Here we will consider experimental data and discover a weakness in the way they are obtained that can contribute to the problem of nonreproducible results.
Background
The discipline of statistics grew up in agricultural and biomedical research…

The lean manufacturing movement evolved from a desire to reduce waste and inefficiencies and improve productivity on the shop floor. Many manufacturers have also benefited from the resulting continuous improvement mindset as engaged employees became empowered to change things for the better.…

‘I don’t see how we can replace the serendipitous idea generation of hallway conversations,” said Saul, the director of quality management for a 1,500-employee enterprise software company, during a planning meeting about the company’s post-vaccine return to the office. “If we don’t return to the…

This isn’t a new story: A novel technology disrupts society, bringing with it many benefits but also major risks and costs. We saw it during the Industrial Revolution, which vastly improved the average living standard but also led to poor labor conditions and environmental degradation, all within a…

Most of the world’s data are obtained as byproducts of operations. These observational data track what happens over time and have a structure that requires a different approach to analysis than that used for experimental data. An understanding of this approach will reveal how Shewhart’s generic,…

Welding technology has progressed over the years, thanks to innovations that improve accuracy and overall productivity. Some advances have been in welding automation handled by advanced robots. Other breakthroughs rely on artificial intelligence (AI) and machine vision for better defect detection.…

You may recognize the following quote from Friedrich Nietzsche, or more recently from Kelly Clarkson: “What doesn’t kill you makes you stronger.” I’ve thought about this often during the last 22 months in context of the horrible pandemic and, more parochially, in relation to the efforts of many…

I’m a chemical engineer. The fundamentals of the chemical engineering profession were laid down 150 years ago by Osborne Reynolds. Although chemical engineering has seen many advances, such as digital process control and evolutionary process optimization, every engineer understands and uses Reynold…

Communities across the U.S. Southeast and Midwest are assessing damage from the deadly and widespread tornado outbreak on Dec. 10–11, 2021. It’s clear that the cleanups will take months and possibly years.
Dealing with enormous quantities of debris and waste materials is one of the most…

In 1996, the TSSC (Toyota Production System Support Center) began working with my company to create one-by-one production capability in our product assembly. Previous to TSSC’s assistance, we’d moved the furniture and machines into cells, creating the appearance of flow production, but we lacked…

Shigeo Shingo was able to summarize entire concepts in single phrases, such as “paint parts, not air.” This meant that paint which misses parts in a spray booth constitutes wasted material and also an environmental aspect. “Ship product, not air” defines similarly empty space in packaging as wasted…
