One of the cornerstones of quality and lean Six Sigma is data: “We insist on it.” “Don’t tell us what you think the situation is; let the data do the talking.” “In God we trust—all others bring data.” You get the idea.

I found that training to run a marathon is a lot like completing a quality improvement project. I ran my first full marathon in November 2011, and as I was completing my training, I came across this quote about quality improvement from V. Daniel Hunt, quality management improvement author and CEO of Technology Research: “Quality is not a sprint; it is a long-distance event.”

During the first winter storm this year in the Northeast, I found myself, along with hundreds of thousands of folks in the area, without power for the better part of a week. It was a long wait before the lights came on… and the heat.

Heck, they had to send the National Guard to my town, and an adjacent one, to start clearing downed trees.

A short time after I moved into operations as the vice president of manufacturing, our assembly department made an early and, dare I say, imperfect attempt to realign the factory floor for ease-of-material delivery and pick up. I would not describe this as improved flow because we were still delivering heaping piles of kitted orders to the factory by the pallet-load.

At a recent health-care conference I had a conversation with Mary, a Six Sigma Black Belt for a 700-bed hospital. She told me that the hospital had only a few copies of Minitab software, which was shared by several people. She was always being asked to close out of the program so that someone else could use it.

For the last decade, people have come by my booth at the American Society for Quality (ASQ) World Conference on Quality and Improvement and asked: “Isn’t there a better way to implement Six Sigma that doesn’t cost so much or take so long?” Of course there is, but conventional wisdom inhibits the spread and benefits of Six Sigma. Even our largest customers rarely train more than 250 Green Belts and five Black Belts a year.

Ask almost anyone what is the No. 1 requirement for Six Sigma success, and he will say: top leadership commitment. It’s easy to look at Six Sigma successes like General Electric (GE) under Jack Welch and use them as evidence of the power of leadership commitment. The belief is so often repeated that it has become part of the Six Sigma lore, but does it have any scientific support? Sadly, I say the answer is no. That myth and several others do more harm than good when a company begins a Six Sigma initiative.

Some lies you can see a mile away: “The check is in the mail.” “Your table will be ready in a few minutes.” “I didn’t say that.” “This won’t hurt a bit.” Add to this rather long list some lies of the lean variety. I’ve heard more than my fair share.

I was listening to Alan Robinson present recently at the Lean Systems Summit about the power of “small ideas.” Alan wondered aloud why so many organizations continue to pursue the few million-dollar ideas while small ideas account for more than 75 percent of the innovation outcome.

Any article about control charts leads to inevitable (and torturous) discussions of special cause tests—all nine of them. No wonder confused people continue to use things like trend lines. But I’m getting ahead of myself.
