Indeed it is.
Often know as the "Father of Quality" W.E. Deming's work on statistical process control is fundamental to designing/implementing/operating a well controlled modern process. Well designed and controlled processes produce output that falls within the QC/QA control limits. I does take design, doing, statistical monitoring, controlling, re-doing, from lessons learned if operating properly/rigorously. The result is continuous process improvement.

edit: Since this is BF C&V it was Japanese industry in the post WWII era who whole heartedly embraced Deming's methodology/ethos w/ profound results even in humble bicycle manufacturing. This goes a long way in understating why a Miyata Pro was perfectly straight, durably finished & affordable while most (face it almost All) "artisan" built Italian framesets of the era were "not so much" of that boring Quality stuff. Did someone say "Soul"? Deming didn't.
