Conventional wisdom says that the higher you go, the easier it is to get things done. Not necessarily. Paradoxically, when you get promoted, positional authority often becomes less important for pushing agendas forward. Like Julia, you may indeed gain increased scope to influence decisions that affect the business, but the way you need to engage may be quite different. Decision making becomes more political—less about authority, and more about influence. That isn’t good or bad; it’s simply inevitable.
