14 layers is insane, but 3 to 5 is on the real low side for a $300B corp with lots of massive studios too. The vision presented is gonna be real awkward for companies working on more than 1 game at a time, or with huge 200+ employee teams. Activision-Blizzard-King in particular, World of Warcraft has a handful of sub-teams that have to coordinate stuff and Call of Duty runs on coordinated yearly releases.

I can easily imagine 7 layers for WoW or 8 layers for CoD. That's not bloat, just the inevitable end-result of Satya Nadella being ultimately responsible for approving the salary of whoever's writing the latest Call of Duty, the main project of a wholly owned subsidiary (the four studios making CoD on rotation) of an acquired company (Activision) of Microsoft's side project gaming division (XBOX).
