Stack ranking causes political backstabbers to rise to the top and filters out the conscientious. It probably functions well enough in companies that are fundamentally extractive, but it will put a company that is supposed to innovate on a self destructive spiral.

Microsoft improved a lot ever since it dumped stack ranking.

Microsoft was using per team stack ranking, Google global stack ranking. That's a huge difference I think. The problem is that the managers go to the promotion commitees and started exchanging promotions with eachother, so the system that was working before doesn't work anymore.
