You'll find a handful of announcements if you google "microsoft new review system". http://www.theverge.com/2013/11/12/5094864/microsoft-kills-stack-ranking-internal-structure http://www.theverge.com/2013/11/12/5094864/microsoft-kills-s... is helpful as it includes the memo that introduced the new system. What I have not seen is any substantial discussions about the new system recently, which would be useful since the FY has now wrapped and we have had our first review under the new system. Speaking only for myself, I don't really know how different the new system is than the old system, but I also didn't see a lot of problems in the old system. This may be because my group is somewhat odd (we're not in Redmond.)
