Earned-value analysis. A project budget calls for the following expenditures:TaskDateBudgeted AmountBuild formsApril 1$10,000Pour foundationApril 1$50,000May 1$100,000Frame wallsMay 1$30,000June 1$30,000Remaining tasksJuly 1 and beyond$500,000Define each term in your own words, calculate these values for the above project, and show your work:Budgeted cost baseline (make a graph illustrating this one)Budget at completion (BAC)Planned value (PV) as of May 1Earned value (EV) as of May 1 if the foundation work is only two-thirds complete. Everything else is on schedule.SV as of May 1.Actual cost as of May 1 is $160,000. Calculate the cost variance (CV) as of May 1.Schedule performance index (SPI)Cost performance index (CPI)Estimate to complete (ETC), assuming that the previous cost variances will not affect future costsEstimate at completion (EAC)
