The critical path is achieved by performing a critical path analysis. The critical path is the longest path through the entire network. The critical path is the shortest time in which the project can be completed and any delay in any of the critical path activities will delay the entire project.

To get the critical path I had to perform a critical path analysis which was to determine the Earliest Start (ES), Earliest Finish (EF), Latest Start (LS), and the Latest Finish (LF). Once I established their ES and LF then I subtracted these numbers to determine which will give me a 0 slack time. The ones that gave me a 0 slack time was my critical path activities. Slack is the length of time an activity can be delayed without delaying the entire project. The critical path activities (projects) have no slack time. Slack time is calculated by: (LF-EF= or LS-ES = Slack Time)

The critical path for the Rockfest is A-B-D-E-F-G-O, if calculated correctly then this will equal the duration of the planning for Rockfest which is 34 weeks, it will take to complete the projects. To achieve the total duration time for the Rockfest project in weeks is by adding the activity time in weeks for A-B-D-E-F-G-O:

A-B-D-E-F-G-O= (7+3+5+6+4+2+7) = 34 weeks duration of Rockfest Project.
