=== Activity-on-Node ===
The Activity-on-Node (AON) technique uses nodes to represent individual project activities and path arrows to designate the sequence of activity completion.<ref>Kramer, S. W. & Jenkins, J. L. (2006). Understanding the basics of CPM calculations: what is scheduling software really telling you? Paper presented at PMI® Global Congress 2006—North America, Seattle, WA. Newtown Square, PA: Project Management Institute.</ref> Nodes are labelled using information pertaining to the activity. According to Project Management, nodes should at least display the following information:<ref>{{Cite book|last=Pinto|first=Jeffrey K.|url=https://www.worldcat.org/oclc/1007502136|title=Project management : achieving competitive advantage|date=2019|isbn=978-0-13-473033-2|edition=Fifth|location=New York, NY|pages=316–319|oclc=1007502136}}</ref>

Start and finish times are used to determine the [[Critical path method|critical path]] of a project. [[Float (project management)|Activity float]], or slack, time is used in project crashing.
