The intermittent failure was the most serious type of failure at Western
Electric. Costing 150 demerits in the production quality scheme. 300 in 30 days
cost the who section their monthly bonus money.
The current production lot would be 100% re-inspected for additional
failures. The two previous lots would be pulled from the warehouse and 100%
tested. The intermittent failure causes far more damage than an outright failure
that can be easily found and repaired.
More components are consumed in repair attempts, and more loss of service
complaints must be dealt with. More man hours down the drain. It used to be,
that in the phone business quality required a 20 year trouble free life span.
And better yet, compatibility with all previous systems. The central office, the
size of several ranch houses, has been replaced by a little green fiber glass
box at the base of a pole in the country.
