Since the activities are represented as arrows, the length of the arrow shows the activity duration. The relationships between the activities are represented by nodes. The arrow diagram shows the activities as arrows. Precedence Diagram Method or Activity on Node Method (PDM).Arrow Diagramming Method or Activity on Arrow Method (ADM).While creating a work schedule we use two common methods Enables to perform critical path calculations.Enables to see the activities and activity dependencies.Typically, a project network diagram has two main objectives Network diagrams create a framework to demonstrate activities and the activity dependencies from the start to the end date of the project. The PERT Method, Critical Path Method, and Gantt Charts are used along with the project network diagrams. Project Network DiagramsĪ project network diagram is a visual presentation tool used to demonstrate a project schedule. In this article, we will talk about common scheduling terms and methods such as the critical path method, arrow diagramming method, and project network diagrams. The dependencies show the order in which the activities will be performed. Unlike the arrow diagramming method, activities are represented as nodes or boxes and linked by one or more dependencies. The PDM is used along with the critical path method.
