A construction project has indirect costs totaling $40,000 per week. Major activities in the project and their expected times in weeks are shown in this precedence diagram.
Crashing costs for each activity are:
a. Determine the optimum time–cost crashing plan.
b. Plot the total-cost curve that describes the least expensive crashing

Using the diagram, find:
The critical path.
How long it will take to complete the project?
How does simulation determine the probabilities of various project completion times?
What is "slack" and why is it important?
Why is activity-on-arrow (AOA) or activity-on-node (AON) of significant value to the project manager?
How is the uncertainty in project scheduling dealt with?
Should the critical path activities be managed differently from noncritical path activities? Explain.
The table below contains data for the installation of new equipment in a manufacturing process for a steel corporation. Your company is responsible for the installation project. Indirect costs are $6,000 per week, and a penalty cost of $10,000 per week will be incurred by your company for every week the project is delayed beyond week 15.

- Farihah is a project manager for a systems development project involving a new database application for her organization’s human resources department. Despite Farihah’s best efforts at estimating the time requirements for the project, the team has missed the deadline for completing the Analysis Phase and producing the System Proposal. Farihah had estimated during her 6-week Planning Phase that Analysis would require 2 months, but the team finished the System Proposal 2 weeks behind their planned target date. Based on her discussions with the team members, Farihah believes that the system is more complex than she originally thought. Should Farihah adjust her timeline, or can she try to make up for the lost two weeks?
