Using the information from the following table, create an AON network activity diagram.
a. Calculate each activity TE (rounding to the nearest integer); the total duration of the project; its early start, early finish, late start and late finish times; and slack for each activity. Finally, show the project’s critical path.

b. Now, assume that activity E has taken 10 days past its anticipated duration to complete. What happens to the project’s schedule? Has the duration changed? Is there a new critical path? Show your conclusions.
