Using AON notation, carryout both a forward and backward pass. What is the estimated total duration for the project? Identify all paths through the network. Which is the critical path? Which activities have slack time? Identify all burst activities and merge activities. Now, assume that activity E has taken 10 days past its anticipated duration to complete. What happens to the projects schedule? Has the duration changed? Is there a new critical path? Show your conclusions.
