CHRO searches fail not because companies hire bad candidates. They fail because companies don't know what they're hiring for. The board remembers the HR executive who handled compliance. The CEO wants a strategic thought partner but can't articulate what that means. The search committee evaluates candidates against criteria that don't predict success in the actual role. The solution isn't more thorough interviews. It's clarity about what the role actually requires at this specific company at this specific moment, before the search begins.
