The critical path has been a major breakthrough in modern management as it facilitates project management, thereby enabling effective and efficient management of gigantic projects almost independent of their size. The basic structure is the precedence diagram of the project, a directed graph which shows the project's logic the dependencies between the activities of the project. Adding estimated duration to each activity creates the project network. The longest path in this network is the critical path, whose length is a lower bound on the duration of the project. A major flaw of the critical path method is the disregard of the required resources and their availability, which might have significant effects on the project's schedule.
