Well, the need for testing should be kept to a minimum. It has

I guess you're referring to this:
"3. Cease dependence on mass inspection
Eliminate the need for mass inspection as the way of life to achieve
quality by building quality into the product in the first place.
Require statistical evidence of built in quality in both manufacturing
and purchasing functions."
I'm not an expert on Deming and his list of principles, but if I
wanted to apply that advice to the creation of software, I'd see that
as an incitement to reduce *manual* testing, specifically through the
use of tools such as unit testing (along with, of course, static
analysis where applicable) to provide the required "statistical
evidence of built in quality"
Thanks for looking that up. I've been tidying up my library lately and
could not find the Deming book. It'll probably turn up when I'm not
looking – I should have tested my tidying!
It's not to say, don't bother with testing, just I think you can't
rely on it, just as you can't rely on anything in writing software –
we still get it wrong. Even those of us sensible enough not to do
Windows.
We sure do spin off on some wild tangents on this list! :)
Probably should have been discussing on Objective-C list, although
this does touch on issues of the development environment as a whole I
guess.
