The larger and more complex a company becomes, the more important it is for senior managers to train employees at every level, acting autonomously, to make prioritization decisions that are consistent with the strategic direction and the business model of the company. That is why successful senior executives spend so much time articulating clear, consistent values that are broadly understood throughout the organization. Over time, a company's values must evolve to conform to its cost structure or its income statement, because if the company is to survive, employees must prioritize those things that help the company to make money in the way that it is structured to make money.
