I worked with Ferrucci in BW. The internals of the employee rating system that preceded him were hilarious. In short: Everyone is encouraged to rate anyone else in a variety of categories, as often as possible. Every rating is public. You know who is rating you, and how they did it. Those ratings are put together to get a score in every category, and can be seen by anyone. It's your Baseball Card. The problem is that…
It would be so cool if someone could apply game theory for mortals that could digest these systems and show how to make them more "fair". It may be an impossible task but it seems worthy of exploration.
