I woke up yesterday morning at 6 a.m., downed a glass of juice, showered, got dressed, grabbed my briefcase, and ran out the door. I arrived at the office at 7 a.m. Waiting for me were nearly 50 e-mails; a couple of them were junk, but most were from actual humans to actual, little ol’ me. When did I get so popular? Soon thereafter the phone started ringing--advertisers, subscribers, contributors, vendors, trade partners, etc., etc., etc. By 7:30, I was already way behind.

Better Than 5 Whys

I liked the way Craig Cochran discounted or lessened the credibility of the 5 Whys (“Don’t Fail Your Customers With the 5 Whys,” February 2009). He provided excellent rationale for its limitations. His alternatives were good; however, I do not believe they can replace Ishikawa’s use of the fishbone technique. While with IBM, I had a class in defect prevention using the fishbone technique followed by action teams to remedy candidate causes with a resolution to each of the viable candidate causes.

As Dirk Dusharme mentioned recently in this space (“A Bold Step Forward,” June 2008), we at Quality Digest have been working like mad these last few months to launch a major redesign of our web site, conveniently located at www.qualitydigest.com. The primary upgrade involves the addition of streaming video, most of which we script, shoot, and edit ourselves.

Stimulated Yet?

Thank you, Scott Paton, for telling it like it is (“Stimulated Yet?” Quality Curmudgeon, March 2009). The bonuses at AIG and continuing troubles at General Motors make it pretty clear that bailouts don’t work. It’s also time people start taking responsibility for their actions. The real enemy is greed and until we can control the reward system, bailouts, Sarbanes-Oxley, regulation, or any other government program, we will fail, adding even more expense to the problem.

As this is my last column for Quality Digest, I’m delighted to announce that my distinguished predecessor, Donald J. Wheeler, will be writing this column again. You’ll be in good hands.

Suppose you had 16 months of data on an important process (as plotted on the run chart seen in figure 1). For improvement purposes, an intervention was made after the sixth observation to lower this key process indicator. This intervention is equivalent to creating a special cause for a desired effect.
