If a manager doesn’t know how many customers the company has signed on in the past weeks and months, and what strategy discussions are in the works, how does he know how many people he can afford to hire? He has to ask his boss. If his boss doesn’t know the details of the company’s growth, she can’t make a good decision either, so she has to go to her own boss. The more employees at all levels understand the strategy, financial situation, and the day-to-day context of what’s going on, the better they become at making educated decisions without involving those above them in the hierarchy.
