The field of surface metrology is one of the fastest growing areas of engineering and quality management. Because what happens at the interaction between two surfaces can affect the functionality and life span of a product, understanding the places where contact and interactions occur is vital for…
Letting You In On a Little Secret
Steven Ouellette
You know how sometimes you think everyone knows a secret that they haven’t let you in on? Well, I had the opposite happen to me the other day. I assumed everyone knew the purpose for measurement system analysis (MSA), a.k.a. gauge repeatability and reproducibility; but I found out that a number of…

Henry Ford West Bloomfield: More Than a Hospital, An Environment
Bill Kalmar
Several years ago, I penned a column entitled, “Nurse, I’m Ready for My Cappuccino!”  The article was an interview with Gerard van Grinsven,  the new CEO and president of the Henry Ford West Bloomfield Hospital, which was to be located in a Detroit suburb. At the time of my interview, Van Grinsven…
The Weapon of Customer Service
Scott Alamanach
Sometimes when studying something that has become too familiar to us, we can gain valuable new insights by looking at it from a radically different perspective. Much has been written, for example, about how important customer service is for business—so much, in fact, that it becomes easy to lose…

How Cool Are You?
The Un-Comfort Zone With Robert Wilson
My sons recently started talking about being cool, and I recalled my own teenage years and the need to be cool. That driving desire dictated the clothes I wore, the music I listened to, and what subjects I became conversant in. And, yet despite all my motivation and effort, it remained elusive…
The Heart of the Matter
Scott Paton
During my sabbatical from writing this column this summer, I watched an interesting program on the National Geographic Channel’s “Mayday” series1. It serves as a terrific example of how a good root cause analysis can get to the heart of a seemingly complicated problem. The show focused on the…
