Consider the following project activities:
Calculate the expected time (te) for each
activity.
Draw an Activity on Node (AON) diagram to reflect the flow of
these activities.
Calculate the Early Start (ES), Early Finish (EF), Late Start
(LS), and Late Finish (LF) for each activity.
Calculate the slack for each activity.
Identify all activities on the Critical Path.
Use the data to calculate the probability the project will
finish in 20 weeks (Hint: z-score).
