The duration of your project is two years. There are five primary functional areas being worked on by six distinct teams. While some teams are running behind time, others are ahead of plan. In certain areas, there are overruns, but you've also saved costs in others. It is challenging to determine whether you are over or under budget as a result of all of this. During Analysis it is observed that in 9 months of the project, you have already spent 1,650,000/-Rs out of the 4,200,000/-Rs project budget. The CPI is 0.875. a) Calculate Estimate at completion (EAC) and Estimate time to complete (ETC) of the above scenario b) Calculate the Variance at Completion (VAC) by using formula VAC = BAC - EAC and infer the results.
