An advertising project manager has developed a program for a new advertising campaign. In addition, the manager has gathered the time information for each activity, as shown in the table below.
a. Calculate the expected activity times (round to nearest integer).
b. Calculate the activity slacks. What is the total project length? Make sure you fully label all nodes in the network.
c. Identify the critical path. What are the alternative paths and how much slack time is associated with each non-critical path?
d. Identify the burst activities and the merge activities.
e. Given the activity variances, what is the likelihood of the project finishing on week 24?
f. Suppose you wanted to have a 99% confidence in the project finishing on time. How many additional weeks would your project team need to negotiate for in order to gain this 99% likelihood?
