Organizational culture powerfully influences a company’s performance — or at least we say so. I often hear executives reassure me that projects will get done because “we have an execution culture,” or that customers will be well taken care of because “we have a culture where the customer comes first.” At the same time, culture is also one of the great rationalizations for managerial shortcomings. Many times I’ve heard that a project was delayed because “we don’t make quick decisions around here,” which is the managerial equivalent of “the dog ate my homework.”
