A trained mechanical engineer, Mark Chang found himself “totally uncertain and unprepared” the first time he was called on to hire someone else.
“I didn’t even know why I was hired in the first place—what did they like about me?” Chang recalls. “So, how do I go out and look for the next person?”…

Experiments that might require a handful of real-number measurements (variables data) could need hundreds or more attribute data for comparable power, i.e., the ability to determine whether an experiment improves performance over that of a control. Sample sizes needed for ANSI/ASQ Z1.4 (for…

Context involves both the background for the data and how the data behave. This behavior of the data is most easily seen by using two complementary graphs—the running record and the histogram. Here I address the secrets of creating useful histograms.
The first graph mentioned above—the running…

Increasingly dynamic workplaces have made organizational change an everyday reality. Demands for workforce agility require a step up from those commanding—particularly in ongoing measurement and making use of feedback during this breakneck pace of change.

Phil used to be a very senior financial executive. When asked for a number, he would typically provide with a rough ballpark answer, such as, “It’s about 5 percent.” He’d then be peppered with questions about how he had arrived at that figure.
After a while, he got tired of this questioning and…

Do you have a regular support group of leaders, or, as I call them, a “mastermind?” Being a member of a mastermind is a powerful strategy used by high-achieving leaders to move ahead quickly and reach their goals.
A mastermind is a small group of dedicated peers who share and support each other…

Airbags, ignition switches, and even emissions software; although large recalls make the news at a regular pace, these are surrounded by scandal. News reports include claims of illegal or unethical activity executed by individuals or larger groups of people. Unfortunately, as new reports expose…

The start of a failure investigation may involve brainstorming, but empirical methods will be required to actually identify a problem's cause. Implementing an improvement action without a confirmed root cause risks a reoccurrence of the issue because the true root cause has yet to be addressed.…

Those of us in the lean world are accustomed to discussing "flow"—where work is performed in an even manner to reduce mura or lack of regularity, one of the three forms of waste. Activities are synchronized, layouts are optimized, resources are available exactly where and when they are needed, and…

I live with a German national, who often tells me that we Americans spend way too much of our lives at work. He also frequently comments that we work much less efficiently than Germans do, during the increased time we’re at work.

Fly-fishing, one of my favorite hobbies, is a lot like process improvement. Here’s how: Fly-fishing seems very simple—you throw a line in the water and wait for dinner. Of course, it’s much more complicated than that because rainbow trout are clever; they won’t bite just anything.
You have to…

Happy belated Pi Day! No, not pie day, Pi Day, which was last week. Pi is that Greek character you’ve heard of but aren’t quite sure what the big deal is. Pi is the ratio of a circle’s circumference to its diameter. As yawn-inducing as that may sound, it’s an important ratio because pi is the same…
