Soviet QC problem.

To be a little more precise...

SPC (Statistical Process Control) is very much a USA original idea. A bit like Levi Jeans or MacDonald Hamburgers. Others guys probably developed it but the USA industrial military complex turned it into an institution. This was achieved pre WW2.

QC (quality control) is an external organization to the manufacturing people. They just go around checking stuff to see if things meet specification. SPC is all about the worker monitoring (i.e. using his/her brains plus graphs and monitoring equipment) into ensuring the work produced is to the best possible standard. In this way lots of incremental improvements (better then the "specified limits") come together to make a superior system manufactured by the thousands with high reliability. The Japs took the idea up from such guys like Denning in the 1950's. The TV manufacturing business changed big time for example

/edit. SPC (manufacturing to the highest possible standard) would be very important on complicated mechanisms like B29 18 cylinder supercharged gasoline engines to get overall good reliability numbers for an Airforce (for example).
