Problem Statement: At month 6, a project has a Planned Value (PV) or Budgeted Cost of Work Scheduled (BCWS) of $500,000. The Earned Value (EV) or Budgeted Cost of Work Performed (BCWP) is $450,000. The Actual Cost (AC) or Actual Cost of Work Performed (ACWP) is $480,000. Calculate CV, SV, CPI, and SPI.

Problem Statement: Using the data from the previous problem (PV = \500,000$,$EV = $450,000$,$AC = $480,000$,$CPI = 0.94), if the original Budget at Completion (BAC) is \1,000,000, what is the new Estimate at Completion (EAC) assuming the current cost performance will continue for the rest of the project?

Problem Statement: A project has a BAC of $2,000,000. At the halfway point, AC = \1,100,000$and$EV = $1,000,000. The project manager realizes the \100k overrun was caused by a singular, unrepeatable event (a freak storm that damaged materials). The rest of the work will proceed at the originally budgeted rate. Calculate the new EAC.

Problem Statement: A project has a BAC = \5,000,000$,$EV = $2,000,000$, and$AC = $2,500,000. The owner refuses to increase the budget, so the project must finish within the original \5M BAC. What cost efficiency (TCPI) must the contractor maintain for the remainder of the work to hit this target?
