"Project management is needed only for situations which are out of the ordinary; but when the need exists, this may often be the only way by which the task may be handled successfully. These situations require a different attitude on the part of the top management, the undivided attention of a project manager and different methods for control and communications than those used in the normal routine business situation... Pure project management assigns complete responsibility for the task and resources needed for its accomplishment to one project manager. The organization of a large project, though it will be dissolved upon completion of the task, operates for its duration much like a regular division and is relatively independent of any other division or staff group."
