Develop a 3-5-page evaluation of the following EVM terms: Earned value (EV). Planned value (PV). Cost variance (CV). Schedule variance (SV). Cost performance Index (CPI). Schedule performance index (SPI). Estimate at completion (EAC). Budget at completion (BAC). Your evaluation should include: The definition. The contribution to project and benefit to project success. An example. A minimum of two academic sources. Part 2: Variance Calculations Develop a one-page analysis for costs and schedule variances using the following scenario: Assume that you have completed three months of the project. The BAC was $120,000 for this six-month project. You can also make the following assumptions: PV = $60,000. EV = $55,000. AC = $50,000. Complete the following: Calculate the cost variance, schedule variance, cost performance index (CPI), and schedule performance index (SPI) for the project. Indicate how the project is doing. Is it ahead of schedule or behind schedule? Is it under budget or over budget? Use the CPI to calculate the estimate at completion (EAC) for this project. Is the project performing better or worse than planned? Use the SPI to estimate how long it will take to finish this project.
