What is a project network diagram?

A project network diagram is a visual chart outlining the sequence of steps needed to complete a project. Project network diagrams are commonly used in service industries that require tasks to be completed by certain deadlines.

A project network diagram is often used as a schedule to outline the length of time needed for a project. A project network diagram commonly contains parallel tasks that are completed during the same time frame, as well as sequenced events that are dependent on one step being completed before the next one can begin. A diagram is helpful in identifying which steps on a project are falling behind that may need additional resources.
