Except it's not hard proof at all - no one person in a company can ever be even the primary reason for that 10 million profit. Further what happens in the years

Except it's not hard proof at all - no one person in a company can ever be even the primary reason for that 10 million profit. Further what happens in the years that by the same metric they lose a company 10 million... Btw my current company offers bonus vacation days instead of financial incentives, and they go to every one in the team responsible for achieving product goals. I feel a little guilty as I'm enjoying that benefit today despite not having been at the company at the point the goals were met! I like the idea though...
