Textbook Question
Chapter 6, Problem 12E
You are creating a customer database for the Lehigh Valley IronPigs minor league baseball team. Draw a project network given the information below. 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.
