4. Earned Value. (20 points) Define the following: TBC, CBC, CAC, CEV, CPI, CV, and FCAC. What formulas are used to calculate CEV, CPI, CV, FCAC (3 methods for FCAC), and SPI? Assume you are the project manager and based on your customer's requirements you have determined there are four main tasks in a Dream Backyard project. Each phase has been assigned a TBC. Specifically, the customer wants a pool and spa built (Task 1 - $50,000); all plumbing, electrical, and mechanical installed (Task 2 - $20,000); a pool deck with planters and a raised fire pit (Task 3 $15,000); and landscaping and clean up (Task 4 - $5,000). You estimate this will take 5 weeks to complete. The costs are budgeted as follows: - Budgeted Per Week (in 000's) TBC 1 2 3 4 5 Task 1 50 15 20 10 5 Task 2 20 6 11 1 Task 3 15 9 Task 4 5 242 23 3 I What is the total cumulative TBC? What is TBC at the end of week 4? Assume 4 weeks have passed and these are the actual costs per week: Actual Costs Per Week (in 000's) 1 2 3 4 Task 1 18 25 12 6 Task 2 5 6 3 Task 3 3 0 Task 4 52 5 2 What is the CAC at the end of week 4? Below is the cumulative percentage of work complete per task per week: Cumulative Percentage Complete 1 2 3 4 Task 1 40 62% 85% 100% I Task 2 25% 75% 90% Task 3 7% 7% 45% Task 4 10% What are the CEV, CPI, and CV at the end or week 4? What is the SPI?
