“Attention CIOs: Looking for an opportunity to serve your country in a post-9/11 world? For the incredible challenge of defining IT infrastructure that will support FBI investigations into terrorism, espionage and international crimes?” This is the ad the U.S. Federal Bureau of Investigation ran recently in The Wall Street Journal. The US$4 billion agency at the forefront of U.S. homeland defense is seeking a successor for Bob Dies, a career IBM executive who took the bureau’s top IT job in July 2000. Applications closed in April. It could take until later this summer to fill the post, the FBI says.
