In project management Network Diagrams show what needs to be done and in what order it needs to be done.
In project management jargon the network diagram is "the logical representation of tasks that define the sequence of work on a project". It may include start and end dates, task names, and the organization or person responsible for the delivery of each task. It should show, at a glance what needs to happen and in what order to deliver a project.
Why do you need a Network Diagram?
Network diagrams are useful because they.
show the sequence of tasks and the dependencies between them.
help to demonstrate how the project can be delivered
allow the project to be scheduled against time and resources
Network diagrams can become very complex stretching over multiple sheets of A3 or even A0 paper covering office walls. For this reason network diagrams are sometimes skipped in the project planning process - this is big mistake because it leads to unrealistic project schedules. Thankfully, there are many project planning tools (software or online tools) that enable you to easily create a network diagram, which can then be turned into a Gantt chart or to view a network diagram of your project Gantt chart.
