Drive necessary to make the project a success?
"The Bank CIO (Gerry Pennell) .. left the organisation in late 2008 .. With his departure, the organisation lost some of the capability and drive necessary to make the project a success."
Having seen that a disaster was coming, mostly caused by his own bad decisions, decided to jump from a sinking ship more likely. If a project fails because one man leaves them maybe it wasn't much of a project in the first place.
