Thee Mr. Drukker said it this way “ There is nothing more wasteful than doing better that which should not be done at all” I likely butchered the exact quote but I am close. He was the MFG Guru for a long time.
Reminds me of "If it ain't broke, don't fix it" followed immediately with "Change for the sake of change" and "Planned obsolescence"
