I would be worried that it make performance management of
managers difficult. Which is to say a manager who fires people as a way of preventing themselves from being fired. The trick being "Yeah, last quarter did kind of suck but we fired that loser Bob, this quarter will be great." In fact there are a couple of reasons why the quarter was poor, it could have been poor Bob but it could also be the manager isn't cutting it. Unless the group has the option of voting the manager out of the organization, the whole "save the best, fire the rest" algorithm has problems. Or more accurately it has a blind spot with respect to management.
The interesting question for NetFlix will be how durable it will be as a structure. My impression is that it selects for the wrong attributes in management. But time will tell.
