You’ve distributed the responsibility for increasing diversity. Its standard: you probably have a campus recruitment team, a separate group driving lateral hiring, and a diversity department concerned with retention and inclusiveness. Recruitment teams focus on hiring goals, but they aren't accountable for low well new employees perform or how many remain after two years. Diversity departments, which do track new hires' success (and, unlike recruiting, can commit funds to programs beyond the current budget cycle), are disconnected from recruitment strategies.
