At the Defense Information Systems Agency, it is not easy to even suggest minor changes to the status quo, laments DISA’s chief, Air Force Lt. Gen. Charles Croom. “I work in a bureaucracy of 15,000 folks — 6,600 military and civilians, 8,000 contractors. Many have worked there for 20, 30 years. How do you get them to recognize that the way they did business yesterday may not be the way we want to do business tomorrow?” One of the phrases Croom often hears at DISA is, “If it ain’t broke, don’t fix it,” he says. “That’s the wrong statement.”
