Project Management has gotten even more difficult due to the numerous complex obligations of managing a project. The commonly utilized network approaches and the tools that assist in completing the project and carrying out the duties are far more than two decades old. The precedence diagramming method (PDM) is a strategy for constructing a project schedule network diagram that uses nodes to represent tasks and associates them with projectiles that indicate dependencies. This is the activity-on-node approach (AON). The following precedence diagram is a crucial result of the sequence activities process. The actions described in the defined activities process are sequenced as particular activities that rely on the sequence activities process. The precedence diagramming technique (PDM) is the most well-recognized strategy for drawing network diagrams, whereas the network diagram depicts project activities and their interrelationships. As a result, in the precedence diagram, one method, certain affiliates and dependencies between the activities are normal.
