That works in sales, where one salesperson runs the whole engagement and can clearly claim responsibility for the revenue and thus be directly compensated with a proportion of it. But in engineering you need people to be thinking big picture, thinking collaboratively, taking risks, doing long term development, cleaning up technical debt. If you overly tie compensation to product revenue, you risk incentivizing your entire engineering staff toward short-term bolt-on-the-feature thinking.
