A New Look at Network Diagrams

Network diagrams have been a cornerstone of project schedule analysis since the PERT and CPM methods of the late 1950s, yet most practitioners today experience them only through the Activity-on-Node lens of tools like Microsoft Project — where tasks are boxes, dependencies are lines, and hammock tasks and event-based logic require awkward workarounds.

In this session on May 13, we’ll start with a practical walkthrough of what MS Project’s Network Diagram view can and can’t do, then shift perspective entirely by introducing Activity-on-Edge modeling as implemented in ProjectXL.

You’ll see how moving activities from nodes to edges unlocks first-class hammock tasks, true event-based dependency ties, and a smarter Link Builder that makes complex schedule logic faster to build and easier to validate — giving schedule planners a more rigorous and maintainable foundation for integrated baseline development.
