Key element in developing a PERT diagram,”1. Activities-list of activites in project and their dependencies 2. nodes/events-indicating the begining or end of an activity 3. network lines show inter dependecies of the events 4.indication of the critical path the sequence of dependant events the sum of the longest duration Indication of slack-time events not on the crtical path have a slack time
extra time for that event that does not effect the timing of other events thus not effecting the project time. That means that can fall behind schedule and there is no impact on the project completion rate. http://www.projectkickstart.comwww.minuteman-system.com”
