I made up the "Schumpeter curve" thing, so you're unlikely to find it, I'd think. Of course it refers to how long the product/company will be alive and relevant.

It wears on people, but guys in combat get used to other people in their outfit dying eventually. This is nothing compared to that.

I am extremely sympathetic with wanting it to work better, but again, that which cannot be easily measured does not exist.

An alternate strategy is to do this surreptitiously and present it as a fait accompli, but that has risks.
