I believe that s1t5 is trying to say no one does it because it is very hard to do.

Especially in a bigger company, where the work you do is tied to so many others' work in the company (sales, etc) - how do you expect them to figure out what the value of the work you did is, vs your teammates, let alone vs all the non-SW folks involved?

Example: You could have done a great job, but someone further down the pipeline screwed things up and the product never got released, and your code is never reused. This is a case where your work produced no value to the company (through no fault of your own). Should you get paid $0?
