I have daily conversations with manufacturer plant managers, quality managers, engineers, supervisors, and plant production workers about challenges when using statistical process control (SPC). Of the mistakes I witness in the application of SPC, I’d like to share the five most prevalent; they…

‘We’ve always done it that way” explains why many suboptimal and even obsolete methods are taken for granted. The range chart for statistical process control (SPC) is, for example, somewhat inferior to the sample standard deviation chart, and it is almost certainly a holdover from when all…

In part one of “New Spin on the ‘Stand in a Circle’ Exercise,” I described how Taiichi Ohno, the creator of the Toyota Production System, used the “Stand in a Circle” exercise to help managers identify waste in their operations.
During this exercise Ohno would take a manager or student…

In the 1990s, Omnex worked with Ford Motor Co. to develop the Ford quality operating system methodology, which with maturity and broad experience has evolved into Omnex’s business operating system (BOS) process.
The quality operating system promised and has delivered the following: • Cross-…

Building airplanes and spaceships poses some of the most unique engineering and manufacturing challenges mankind has ever encountered. Fortunately, you don’t have to build rockets to benefit from rocket science. Manufacturers of most any product can improve their efficiency and…

During the mid-1940s, Taiichi Ohno established the Toyota Production System, which is primarily based on eliminating nonvalue-added waste. He discovered that by reducing waste and inventory levels, problems get exposed and that forces employees to address these problems. To engage the workers and…

You can be known as a hard worker and counted on to tie up loose ends, but fall behind when co-workers’ tasks are on hold until yours are complete, and you’re perceived as needing an attitude adjustment. What would you want to do? Place blame or work on a remedy? There is a solution: Personal…

There are those days where your personal kanban is on fire. You’re in a state of flow and tickets are just moving right along. The days go by and you look at your “done” column… it’s full. Really, really full.
The “done” tickets seem to swim. There are so many of them! You’ve been productive, but…

Reading the Automotive Industry Action Group’s CQI-8 Layered Process Audit (LPA) Guideline, you might notice a line saying LPAs are “completed on site ‘where the work is done.’”
For lean manufacturing experts, this specific quote might bring to mind gemba walks, a method where leaders observe and…

Recent reports suggest that terrorists can now create bombs so thin that they cannot be detected by the current X-ray screening that our carry-on bags undergo.
In an effort to protect against such threats, the United States is considering banning laptops and other large electronic devices in the…

n part one of this two-part series, I described the need for empiricism in root cause analysis (RCA). Now, I’ll explain how to achieve empiricism when performing a RCA by combining the scientific method and graphical explorations of data.
The statistician John Tukey believed data should be…

The world faces a new crisis situation more or less every day—be it political, economic, or humanitarian. Wherever a crisis is experienced, echoes are felt around the globe. In the digital age, social media conveys crises in real time, resulting in rich portfolios of pictures, videos, written…

There are many reasons for performing a root cause analysis (RCA). These reasons include determining the cause of a failure in a product or a process as well for determining the root cause of the current level of performance when a product or process has been selected for improvement.
There are…

A few months ago I told you how my wife and I had found a midcentury remodel project only a couple blocks away from where we currently live. We wanted to create a “lean home”—smaller with a simple layout, less storage space, and as few walls and doors as possible to optimize flow. The remodel has…

For me, Taiichi Ohno and Shigeo Shingo are a bit like the Lennon and McCartney of waste elimination. Together they frame the technical and social sciences of what we call lean today.
Taiichi Ohno tells us there are seven wastes that account for 95 percent of the elapsed time between “paying and…

I remember my first trip to Michigan in 2012. I was covering the Ford Motor Co.’s annual Trend Conference and had the opportunity to meet Alan Mulally, who gave a compelling presentation explaining the vision, strategy, and implementation of the One Ford plan. I was impressed more with the man…

In a similar vein to Donald Wheeler’s excellent article on process capability confusion I would like to submit the following example of thinking that you are doing the math right and getting an answer that can get you into real trouble.
Consider the following capability assessment problem. The…

Three transportation revolutions are in sight, and together they could help reduce traffic, improve livability, eventually save trillions of dollars each year, and reduce urban transportation carbon dioxide (CO2) emissions by 80 percent or more worldwide by 2050. That’s according to a report…

My eye was caught recently by a gossipy article concerning NASA’s suit situation. Spacesuits, that is, not the standard-issue coat and trousers worn by many earthbound employees at the agency. It seems its Office of Inspector General (OIG) issued a thumbs down following a spacesuit audit, warning…

You may have heard that it takes 21 days to form a new habit. Well, it turns out that’s just a myth. Researchers found that, on average, it takes people more than two months before a new behavior becomes automatic. So what does that have to do with your office ergonomics process? A lot, especially…

In his February 2017 Quality Digest column, “Don’t We Need Good Measurements?” Donald J. Wheeler recommends that a measurement system contributing up to 80 percent of the overall variation (on the variance scale) is good enough to detect persistent mean shifts when using a process behavior (…
