The precedence diagram method (PDM) is a tool for scheduling activities in a project plan. It is a method of constructing a project schedule network diagram that uses boxes, referred to as nodes, to represent activities and connects them with arrows that show the dependencies. It is also called the activity-on-node (AON) method. Key elements ...

Arrow diagramming method (ADM) is a network diagramming technique in which activities are represented by arrows. ADM is also known as the activity-on-arrow (AOA) method. Usage. ADM is used for scheduling activities in a project plan. Precedence relationships between activities are represented by circles connected by one or more arrows.
Once this step is complete, one can draw a Gantt chart or a network diagram.. A Gantt chart created using Microsoft Project (MSP). Note (1) the critical path is in red, (2) the slack is the black lines connected to non-critical activities, (3) since Saturday and Sunday are not work days and are thus excluded from the schedule, some bars on the Gantt chart are longer if they cut through a weekend.
Network mapping and drawing software support IT systems managers to understand the hardware and software services on a network and how they are interconnected. Network maps and diagrams are a component of network documentation. They are required artifacts to better manage IT systems' uptime, performance, security risks, plan network changes and ...
