Sadly, from what I've read the commission-based approach often leads to worse long-term results, especially in software engineering. It depends on the kind of work, of course. The metric I use (and in this case I have no idea how others look at the problem) is the number of decisions the person has to make, especially having long-term effects or effects on other parts of the company. It's hard to make the right choice for the org when you stand to make a bigger chunk of money right now from the other option.
