A schedule activity that has low total float. The concept of near critical is equally applicable to a schedule activity or schedule network path. The limit below which total float is considered near critical is subject to expert judgment and varies from project to project.
A schematic display of the sequential and logical relationships of the activities that comprise the project. One popular drawing convention is called precedence diagramming. A view of project data in which the project logic is depicted graphically. Frequently called a flowchart, PERT chart, or logic diagram.
A schedule network path that passes the same node twice. Network loops cannot be analyzed using traditional schedule network analysis techniques such as the critical path method.
Network Open End
A schedule activity without any predecessor activities or successor activities creating an unintended break in a schedule network path. Network open ends are usually caused by missing logical relationships.
