What problems do you anticipate in the future? Do you need any resources you do not yet have? Do you need information you do not have yet? Do you know anything that will give you schedule difficulties? Any possibility your task will finish early/late? Will your task be completed under/over/on budget? 14-Jan-22 Project Monitoring & Control 11 11 Monitor progress against the schedule Periodically measuring the actual completion of activities and milestones Comparing actual completion of activities and milestones against the schedule documented in the project plan Identifying significant deviations from the schedule estimates in the project plan 14-Jan-22 Project Monitoring & Control 12 Downloaded by Ram Ale (su.aale047@gmail.com) 12 lOMoARcPSD|13102316 14-Jan-22 Monitor the project's cost and expended effort Periodically measuring the actual effort and cost expended and staff assigned Comparing actual effort, costs, staffing, and training to the estimates and budgets documented in the project plan Identifying significant deviations from the budgets in the project plan 14-Jan-22 Project Monitoring & Control 13 13 A few monitoring methods include: Time measurement; Cost measurement; Labour time measurement; and Work quantity measurement.

The result is amount that should be spent on the task so far. This can be compared with actual amount spent. 14-Jan-22 Project Monitoring & Control 29 29 Earned Value Analysis Methods for estimating percent completion The 50-50 estimate. 50% is assumed when task is begun, and remaining 50% when work completed. 0-100% rule. This rule allows no credit for work until task is complete, highly conservative rule, project always seem late until the very end of project when everything appears to suddenly catch up Critical input rule. This rule assigns progress according to amount of critical input that has been used. Labor or skilled dependent, machine critical input – buy machine complete task – may be misinformation Proportional rule. This rule divides planned (or actual) time-todate by total scheduled time(or budgeted (or actual ) cost-todate by total budgeted cast] to calculate percent complete. This is commonly used rule. 14-Jan-22 Project Monitoring & Control 30 Downloaded by Ram Ale (su.aale047@gmail.com) 30 lOMoARcPSD|13102316 14-Jan-22 Earned Value Analysis Refer to earned value chart – basis for evaluating cost and performance to date If total value of the work accomplished is in balance with the planned (baseline) cost, and actual cost then top mgmt has no particular need for a detailed analysis of individual tasks Earned value concept – combines cost reporting & aggregate performance reporting into one comprehensive chart 14-Jan-22 Project Monitoring & Control 31 31 Earned Value Analysis Baseline cost to completion – referred to as budget at completion (BAC) Actual cost to date – referred to as estimated cost at completion (EAC) Identify several variances according to two guidelines 1. 2. 14-Jan-22 A negative variance is ‘bad’ Cost and schedule variances are calculated as earned value minus some other measure Project Monitoring & Control 32 Downloaded by Ram Ale (su.aale047@gmail.com) 32 lOMoARcPSD|13102316 14-Jan-22 Earned Value Chart – basis for evaluating cost & performance to date 14-Jan-22 Project Monitoring & Control 33 33 Earned Value Analysis - Variances 4 types of variances; Cost (spending) variance (CV) – difference between budgeted cost of work performed (earned value) (BCWP) and actual cost of that work (ACWP) Schedule variance (SV) – difference between earned value (BCWP) and cost of work we scheduled to perform to date (BCWS) Time variance (TV) –difference between time scheduled for work performed (STWP) and actual time to perform it (ATWP) 14-Jan-22 Project Monitoring & Control 34 Downloaded by Ram Ale (su.aale047@gmail.com) 34 lOMoARcPSD|13102316 14-Jan-22 Earned Value Variance - Formula CV = BCWP – ACWP (negative value - cost overrun) SV = BCWP – BCWS (negative value - behind schedule) TV = STWP – ATWP (negative value - delay) Index (Ratios) Cost Performance Index (CPI) = BCWP/ACWP Schedule Performance Index (SPI) = BCWP/BCWS Time Performance Index (TPI) = STWP/ATWP 14-Jan-22 Project Monitoring & Control 35 35 EXAMPLE Assume that operations on a Work Package cost RM 1,500 to complete. They were originally scheduled to finish today. At this point, we actually spent RM1,350. And we estimate that we have completed two thirds (2/3) of the work. What are the cost and schedule variances? CV = BCWP – ACWP = 1500 (2/3) – 1350 = - 350 SV = BCWP – BCWS = 1500 (2/3) – 1500 = - 500 CPI = BCWP/ACWP = 1500(2/3)/1350 = 0.74 SPI = BCWP/BCWS = 1500(2/3)/1500 = 0.67 Spending higher than budget, and given what we have spent, we are not as far along as we should be (have not completed as much work as we should have) 14-Jan-22 Project Monitoring & Control 36 Downloaded by Ram Ale (su.aale047@gmail.com) 36 lOMoARcPSD|13102316 14-Jan-22 Possible to have one of indicators to be favorable while the other unfavorable Might be ahead of schedule and behind costs Six possibilities (see figure next slide) 14-Jan-22 Project Monitoring & Control 37 37 6 Possibilities Earned Value Analysis 14-Jan-22 Project Monitoring & Control 38 Downloaded by Ram Ale (su.aale047@gmail.com) 38 lOMoARcPSD|13102316 14-Jan-22 EXERCISE (Text P.544 Problem 4) A project to develop a country park has an actual cost in month 17 of $350,000, a planned cost of $475,000, and a value completed of $300,000. Find the cost and schedule variances and the three indexes. $ Time t 14-Jan-22 Planned (Baseline) – 475,000 PV=BCWS Actual cost – 350,000 AC=ACWP Value completed – 300,000 EV=BCWP Month 17 Project Monitoring & Control 39 39 Solution BCWS = 475,000 BCWP = 300,000 ACWP = 350,000 CV = BCWP – ACWP SV = BCWP – BCWS CV = 300,000 – 350,000 = -50,000 (negative value - cost overrun) SV = 300,000 – 475,000 = -175,000 (negative value - behind schedule) Cost Performance Index (CPI) = BCWP/ACWP = 300/350 = 0.86 Schedule Performance Index (SPI) = BCWP/BCWS = 300/475 = 0.63 Time Performance Index (TPI) = STWP/ATWP Scheduled Time Work Performed (STWP) can be estimated Time t = Schedule Variance/Slope of Planned costs = -175,000/ (475,000/17) = - 6.26 months Time Difference= 17- 6.26 = 10.74 TV = 10.74/17 = 0.63 14-Jan-22 Project Monitoring & Control 40 Downloaded by Ram Ale (su.aale047@gmail.com) 40 lOMoARcPSD|13102316 14-Jan-22 Critical ratio Sometimes, especially large projects, it may be worthwhile calculating a set of critical ratios for all project activities The critical ratio is actual progress x budgeted cost scheduled progress actual cost If ratio is 1 everything is probably on target The further away form 1 the ratio is, the more we may need to investigate 14-Jan-22 Project Monitoring & Control 41 41 Critical ratio example Calculate the critical ratios for the following activities and indicate which are probably on target and need to be investigated.
