Cooperation must start at the head of a department if it is expected at the other end. The same is true for efficiency. In most large organizations, the amount of time and energy that is squandered in interdepartmental rivalry is enormous. Managers who compete with others inside the company waste valuable resources that should be directed at fulfilling the company’s mission to serve its customers better. Worse, a negative, internal focus can cause the company to miss opportunities, the full effect of which may not be realized for months or even years. Whether you are the head of the department or the newest worker on the staff, you can help your company immeasurably by refusing to become embroiled in internal strife. Compete with yourself to do the best job you can do instead of competing with others.
