I've watched many war room in various employers.

At one (20 years ago), they met for six months to determine why our field offices' network connection to the home office was so pathetic and unusable. It was led by the head of networking. After all those meetings, it was decided that all 1000 independent field offices should upgrade their internet to T1 connections. It didn't help. Another six months goes by, and I hear from my connections in networking that the real problem was the head of networking had installed a half-duplex low-speed ethernet card: all 1000 office's data had been going through a pinhole. It was replaced, and suddenly everything was fine again, other than the hole in the office's pockets for an unnecessary upgrade.

No one ever mentioned it publically.
