IBM has 11 management layers, plus 2-3 non-management layers (not sure about the latter).
If all people on earth are connected, on average, by six degrees of separation, how can an organization have almost 2x more layers and expect to be more "connected" than average humans walking down the street?
The biggest issue is middle management. From Band E to Band B - these execs are mostly useless.
