why even defect prevention isn’t enough

Tuesday, May 12th, 2009

During a recent stay at a reasonably nice hotel, I was looking for a place to hang up my wet raincoat when I noticed this sign on the wall, up high. Clearly there had been problems in the past with sprinkler malfunctions, and after one or more incidents of ‘defect correction’ (fixing the sprinkler malfunctions), someone did root cause analysis (e.g. why? … why? …), identified coat hangers as the culprit, and took this action to try to prevent future defects.

Commendable, right?

But I looked around the entire hotel room and realized I still had no good place to hang my wet raincoat.

This exemplifies a saying I recall hearing in an SEI Six Sigma training class last year, and earlier in a QFD class:
    “Just because nothing is wrong, doesn’t mean anything is right.”
Taking corrective and preventive actions, and driving defect levels towards zero, may be useful and necessary, but is not sufficient to achieve true high quality. Satisfaction of real customer needs matters most. It would be neither hard nor expensive to install a coat hook somewhere in the hotel room for wet/snowy/dirty/… outergarments. Adding this small amenity would not only dilute the temptation to guests who might otherwise hang wet coats on the sprinklers, they’d be less likely to drape them over the chairs in the rooms, which probably isn’t good for the wood or upholstery, …

Photos and the summary report from the 2008 QFD Symposium are now posted. Here are the two pictures I’m in (taken by Mayumi Mazur of QFDI):

getting AHEAD

Thursday, October 30th, 2008

In conjunction with our colleague Elizabeth, Aldo, Qingfeng, and I have recently completed several new papers on the AHEAD method which emerged from a recent software technology evaluation project. AHEAD stands for Attribute Hierarchy-based Evaluation of Architectural Designs; the method blends the SEI’s Attribute-Driven Design (ADD) with the Analytic Hierarchy Process (AHP) to deliver a nice balance between efficiency and accuracy (agility and discipline) in performing objective software technology evaluations. Our research results are just now ‘hitting the press’ … the first paper was well received at the QFD Symposium last week, and two others have been accepted at conferences and will be presented in March. Please check out AHEAD – we’d love to hear your comments and suggestions for improving and applying it!

This blog has been quiet for a while, partly due to a shift in employer focus away from coaching agile, TSP, and CMMI, and towards research in requirements engineering, technology evaluation, and software architecture. I’m delighted to be reviving this blog now with the addition of new topics (including QFD, ADD, AHP, PrIME) and an outstanding new collaborator, Dr. Qingfeng He! It also seems likely that agile coaching activities will resume in the near future, based upon grass-roots demand for Scrum, which we’re excited about. Look for more new posts and publications here in the near future!
