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.
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, the other one is activity on arrow.
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.
Famous quotes containing the words project and/or network:
“I wish to come to know you get to know you all
Let your belief in me and me in you stand tall
Just like a project of which no one tells
Or do ya still think that I’m somebody else?”
—John Ashbery (b. 1927)
“Parents need all the help they can get. The strongest as well as the most fragile family requires a vital network of social supports.”
