QI. A project is being monitored using Project Network Techniques, and the programme has been fully costed. The completed bar chart is attached as Figure la. The following table shows the original duration (as planned) and total budget cost of each activity. The table also indicates the progress situation as determined at the end of week 7 (Time Now), given as percentage complete for each activity. Total cost (0) Original Duration Percentage completion at end of week 7 Activity 101 6 weeks + 1,C00 100% complete 102 3 weeks # 4.00 100% complete 103 5 weeks + 2F.000 60% complete 104 3 weeks # 7.DOO 30% complete 105 5 weeks + 10,000 0% - not started BAC Budget at Completion (Total Project Cost) (a) Using the space below the bar chart on Figure la draw the Baseline 'S curve of the Budget Cost of Work Scheduled (BCWS) for this project. (10 marks) (b) Using the percentage completion figures given above, calculate the Budget Cost of work Performed (BCWP) for this project at the end of week 6. (10 marks) c) Determine the Schedule Variance (cost) and the Schedule Variance (time) for this project at the end of week 7, and indicate these variances on the S curve diagram. (15 marks) Formulae for (d) are given below The Actual Cost of Work Performed (ACWP) at the end of week 7 is $28.EFO. Calculate the Cost Performance Index (CPI) and the Estimated Cost to Complete [ETC) at the end of week 7. From this information, what is the Forecast Cost Overrun on this project?
