Chapter 6, Problem 9E
You are creating a customer database for the Hillsboro Hops minor league baseball team. Draw a project network given the information in the table that follows. Complete the forward and backward pass, compute activity slack, and identify the critical path.
How long will this project take? How sensitive is the network schedule? Calculate the free slack and total slack for all noncritical activities.

Prepare a plan for a small project of moderate complexity (at least 12 activities, with some interdependencies between activities).
Your plan should identify the activity by their beginning and ending nodes and by short, descriptive titles. Estimate the times to
complete the activities. Prepare a PERT/CPM network. Determine critical path and the expected time for completing the project
(Activity Analysis and Event Analysis). Choose a project of some personal interest and knowledge (e.g. building a house, selling a
house, political campaign etc.) Your project will be judged by how completely it identifies all activities, the reasonableness of your
time estimates and the correctness of your analysis.

The expected project completion is

weeks from May 1.
Suppose you are the project manager for the following project: First, draw a network diagram for the
project. Determine the critical path and slack times for all of the tasks. This completes your plan for
the project schedule. During project execution, you become aware of the need to change the duration
of Task 4 to five days.
Meanwhile, Task 3 has been finished one day early, so it only took one day to do. What, if any, effects
do these changes have on your project? What would have happened if you had not been monitoring
the status of the project?

- The managers at AllBirds have operations in multiple countries, which operate on different financial management systems. This has been increasingly challenging for the company, so the Justin is looking to consolidate and integrate the financial management across all locations into a single software system that can operate across the national boundaries. This is a new, complicated and lengthy project, so Justin has identified a set of activity categories that will need to be carefully managed, as noted in the table. Draw the project network, and compute the expected time and variance for each activity.
