Misadventures in Big-Box Land

Regarding “Big Boxes Beware” (“First Word,” Dirk Dusharme, November 2008): If you want to experience grocery-industry customer service at its finest, visit Wegmans. Their employees will load your groceries in your car for free, provide umbrellas for trips to your car in the rain for those who don’t have one, and personally take you to the items that you’re looking for when you can’t find something.

The number of major hurricanes in the Atlantic since 1940 (as we considered in my February column, “First, Look at the Data”) are shown as a histogram in figure 1, below. Some analysts would begin their treatment of these data by considering whether they might be distributed according to a Poisson distribution.

This, I swear, is a true story... mostly.

We own a washer and dryer combo unit made by a large home appliance manufacturer--let’s call them “Maytag.” The washer and dryer are in the company’s Neptune series. We’ve had them for about seven years and they’ve worked flawlessly, until recently.

About four months ago the washer started making an awful squealing noise when it went into the spin cycle. No problem, I thought. We have an extended warranty. I’ll just call the friendly Maytag repairman.

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.
