(4 marks) 2.2.2 Calculate the cost variance (CV) and the cost performance index (CPI) for the first week in this project? Is the project under or over budget? (6 marks) 2.2.3 Calculate the schedule variance (SV) and the schedule performance index (SPI) for the first week in this project? Is the project ahead of or behind schedule?
