CB>Deming management theory would say that testing
CB>increases defects -
RM> This caught my eye... How can testing increase defects?
RM> I can see where testing will discover more defects; I can
RM> even see where, possibly, intervention in the process
RM> MIGHT affect product; but... I can't see how the act of
RM> testing, which is an essential part of quality control,
RM> can increase defects?
CB>Actually, testing to improve quality is not a Deming management process -
CB>that is part of MBO or MBR (management by objective or management by
CB>results). That kind of testing is used when numerical goals to judge and
CB>direct performance.
CB>
CB>However, Deming states that this leads to the following:
CB>Short-term thinking
CB>Misguided focus
CB>Fudging the figures
CB>Greater fear
CB>Blindness to customer concerns
Ok.. These are human failings which are not directly related
to the testing itself, but may be triggered by test results.
CB>However, recently, I came across this book that relates Deming principles
CB>to education and has examples, worksheets, etc. all approved by Deming
CB>before he passed away.
CB>
CB>Have you read anything about Deming?
A little; some of my time working in industry involved an
overview of prevailing thought on process control, etc...
