Mediocre people can't evaluate exceptional people. What mediocre people think is knowledgeable can't be exceptional knowledge, by definition. If you want to find exceptional directors of engineering, you need an exceptional person worthy of being director of engineering to evaluate them.
In seeking victory, not going beyond what everyone knows / is not skilled.
Victory in battle that all-under-heaven calls skilled / is not skilled.
Thus lifting an autumn hair does not mean / great strength.
Seeing the sun and moon does not mean a / clear eye.
Hearing thunder does not mean a keen ear.
So-called skill is to be victorious over the easily / defeated.
Thus the battles of the skilled are without / extraordinary victory, without reputation for / wisdom and without merit for courage.
- Sun Tzu Ch. 4 (Denma translation)
