"Hard (plans, numbers, org charts) is soft. Soft (people, relationships, culture) is hard." Those two sentences-ideas have been the core of my work for decades.
So how about this, from a 12/20/17 Washington Post article:
"Project Oxygen [data from 1998-2013] shocked everyone [at Google] by concluding that among the eight most important qualities of Google's top employees, STEM expertise comes in dead last.

The paper attached here—"Hard is Soft. Soft is Hard. Google Gets a (Big) (Soft) Surprise"—starts with the Google case and moves into other arenas to discuss "Hard is soft. Soft is hard."

It's also, frankly, an excuse to get the Google finding in front of more people: If the Google tale doesn't make you stop in your tracks, I honestly don't know what would!!!!!!!!!! (The excerpt included from Rich Karlgaard's book The Soft Edge is also a "showstopper"—giving conventional wisdom a well deserved good, swift, kick in the butt.)
