As predictable career paths have become extinct in most organizations, managers aspiring to the C-level job are left to their own devices to determine how to advance their careers. Even in companies committed to talent development, guidance to aspiring executives is often vague and contradictory. This happens, executive coach John Beeson argues, because executive promotions are made based on the decision makers' sense of whether or not a manager can succeed at higher levels within the organization. Beeson decodes these leadership criteria—the unwritten rules—that companies use to make decisions about who gets promoted and who doesn't, and identifies the six core "selection factors" that are imperative for success at the executive level Filled with stories of managers who successfully climbed up the executive ladder-and some who struggled- is an invaluable resource for aspiring executives.
