Manpower Quote by Frederick P. Brooks Jr
““Oversimplifying outrageously, we state Brooks's Law: Adding manpower to a late software project makes it later. This then is the demythologizing of the man-month. The number of months of a project depends upon its sequential constraints. The maximum number of men depends upon the number of independent subtasks. From these two quantities one can derive schedules using fewer men and more months.””
