Question 3. (30 points) - Earned Value Analysis, Variances and Indexes At week 8 of a project below to optimize facility layout, assume that the planned values (PV) are based on time proportionality but the "\% Complete" values for earned values (EV) are from the workers actually doing the tasks. a) Calculate the Earned Value (EV), Planned Value (PV), Cost Variance (CV), Schedule Variance (SV), Actual Cost (AC) and Slope. b) Calculate the three indexes, namely cost performance index (CPI), schedule performance index (SPI), and cost schedule index (CSI). Is this project favorable or not, please comment. c) Calculate the budget at completion (BAC), estimated cost to complete (ETC), and estimated cost at completion (EAC) for the project
