Earlier quoted context omitted.
I find the whole variable comp for sales so bizarre. It’s like people trying to claim that the only way to get decent work out of programmers is by giving them comp on lines of code written. Why can’t a salesperson be properly motivated by just, you know, doing their job?
The thing that's unusual about sales is that it's the only metric that anyone's ever found that's (mostly) an exception to Goodhart's Law. Companies would love to pay a lot more people on commission if you could find a way to calculate commissions that gave the desired incentives.
Goodhart's Law still applies to the extent that companies have other goals and sales's incentives totally screw those goals up. But they are very effective incentives at increasing money earned.
