It's a tool used in project management. You have a number of
activities with dependencies between those activities (ie "Building"
can only be complete after "Planning" is finished). Each activity has
a duration and once all the dependencies have been set you can
calculate various properties such as the critical path, the
earliest/latest start/finish for each activity and so on. From the
network you can also generate Gantt charts, resource usage and other
information needed for project control. It's sometimes also called a
Project Network (http://en.wikipedia.org/wiki/Project_network)
