Preliminary plans are underway for construction of a new stadium for a major league baseball team. City officials question the number and profitability of the luxury corporate boxes planned for the upper deck of the stadium. Corporations and selected individuals may purchase a box for $300,000. The fixed construction cost for the upper-deck area is estimated to be $4,500,000, with a variable cost of $150,000 for each box constructed. a. What is the breakeven point for the number of luxury boxes in the new stadium? b. Preliminary drawings for the stadium show that space is available for the construction of up to 50 luxury boxes. Promoters indicate that buyers are available and that all 50 could be sold if constructed. What is your recommendation concerning the construction of luxury boxes? What profit is anticipated?
The decision was made by JMP management that a certain critical development in the overall project will be subcontracted-out to a vendor. JMP has issued a six-month cost plus fixed fee contract for that development, and you are the vendor's project manager. The approved JMP budget for your development is $500,000. A recent Earned Value Analysis that your firm (the vendor) has done shows that you will complete the project four weeks ahead of time, thus depriving your firm of $80,000 of billable time. Among your options are: 1. Since it was the approved budget, go ahead and bill JMP for the entire $500.000. 2. Inform JMP of the project status and completion date, and ask if they'd like to add any features to account for the monies spent. 3. Inform JMP of the project status and completion date. 4. Bill JMP for the $500,000 by adding more work at the end of the project.
Image of Diagram included 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.
