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.

(a) Give the expected project completion date and the critical path. (Enter your critical path as a comma-separated list.)
The expected project completion is
weeks from May 1 with a critical path of
(b) Based only on the critical path, by what date are you 99% sure the project will be completed? (Round your answer to one decimal place.)
weeks from May 1.
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.

- I'm having trouble creating a project network diagram. I don't understand calculating the time and total slack for each activity using forward pass and backward pass. Please explain how to draw and calculate a project network diagram.arrow_forwardConstruct this problem. Draw a network diagram, determine the early start, early finish, late start, late finish, and slack times for each activity (table), determine how long the project will take, and which activities are on the critical path.arrow_forwardSuppose 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?arrow_forward

- 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. Develop an activity schedule for this project, compute activity slack time and identify critical path.arrow_forwardMichael Bai is the project manager for a project to host the graduation ceremony at your university campus, and he needs your advice on developing the project schedule. Explain to Michael the main steps he needs to complete when developing the project schedule (include: identify activities, determine sequence/network, estimate activity durations, and construct the critical path).
