1. Assume that operations on a work package were expected to cost $1500 to complete the package. They were originally scheduled to have been finished today. At this point, however, we have actually expended $1350, and we estimate that we have completed two-thirds of the work. What are the Cost and Schedule variances? Calculate CPI, SPI, ETC & EAC. Interpret the results (what does it all mean).

What are the Cost and Schedule variances? Calculate CPI, SPI, ETC & EAC. Interpret the results (what does it all mean). 2. Find the schedule and cost variances for a project that has as actual cost at month 16 of $540,000, a scheduled cost of $523,000, and an earned value of $535,000. What do the results tell you? February 28, 2004 1 SYS 612 - Project Management of Complex Systems 3. A sales project at month 5 had an actual cost of $34,000, a planned cost of $42,000, and a value completed of $39,000. Calculate the CPI and SPI and explain the message they give the Program Manager. 4. A construction project at day 70 has actual costs of $78,000 and a scheduled cost of $84,000. The Work Package Manager estimates a value completed of $81,000. Calculate SV & CV, CPI, and SPI. What does this tell you? February 28, 2004 2 SYS 612 - Project Management of Complex Systems 5. Given a project planned to cost $12,000 but actual cost to date is $10,000 so far and the project is only 70% complete. Calculate the variances. Should the customer be happy? 6. A project to build a new taxiway at Culpepper Airport is 5 days behind at day 65. It had a planned cost of $735,000 for this point in time, but the actual cost is only $550,000. Estimate the variances and what do they say about the health of the project? Re-estimate if the actual cost to date had been $750,000.
