"How many people, if asked, could tell you exactly where they fit in, and exactly what their duties, authority, and relationships are with every other member in their organization? If an answer could be given at all, it would require much thought and debate. So, it is difficult to visualize an organization in its entirety, and to clearly picture just where an individual stands in it. Because such difficulties exist for an individual, consider the situation in which top level management finds itself when confronted with the same question. And because necessity is the mother of invention, a tool for management has been invented to enable the manager to quickly locate who is responsible for what, and why. This tool we call the organization chart. It is but one of the tools of management."
