New rule: Hire passionate people.
Old rule: Rank your players; go with the A's.
NEW YORK (Fortune) -- At GE under Welch, employees were ranked as A, B, or C players, and the bottom group was relentlessly culled.
"We're an A-plus company," Welch told his executives in 1997, according to Robert Slater's book, "Jack Welch and the GE Way." "We want only A players. Don't spend time trying to get C's to be B's. Move them out early."
