Agreed; applying knowledge about how to
manage quality of a step and repeat process makes sense, but only to another
step and repeat process. Software is definitely not that, despite six decades
of trying to do it more reliably and efficiently. It’s still very much
an individual programmer working on a poorly specified problem and finding ways
to get acceptable results.

A simple lack of belief in and dedication to
Zero Defects(tm).
Jack,
Zero defects is about producing *the same thing* repeatedly and getting the
same result ... i.e. Manufacturing. In software system development, almost
nothing is ever produced more than once so let's not compare producing bolts
with producing ERP systems. I agree that as Larry Johnson is fond of saying,
'Scientists stand on each others shoulders, and software engineers stand on
each others toes' so vast improvements can be made - but that still doesn't
mean Zero defects as in the Mfg industry makes sense wrt software engineering.
Cheers,
David
