Project network

A project network is a graph (flow chart) depicting the sequence in which a project's terminal elements are to be completed by showing terminal elements and their dependencies. It is always drawn from left to right to reflect project chronology.^[1]

The work breakdown structure or the product breakdown structure show the "part-whole" relations. In contrast, the project network shows the "before-after" relations.

The most popular form of project network is activity on node (AON)(as shown above), the other one is activity on arrow (AOA).

The condition for a valid project network is that it doesn't contain any circular references.

Project dependencies can also be depicted by a predecessor table. Although such a form is very inconvenient for human analysis, project management software often offers such a view for data entry.

An alternative way of showing and analyzing the sequence of project work is the design structure matrix.
