A simple example of Earned Value Management (EVM) in action

  1. 1. Simple example of EVM in action © 2014 Planisware
  2. 2. The plan • Our team has been tasked with planting the trees on the plot of land behind our company’s new factory • The plan: – 30 batches of 20 trees (600 trees) – 5 batches per day (100 trees) – budgeted cost per tree 2.90$ (2.5$ per baby tree / 0.40$ for the slow release fertiliser) → total budget 1,740$ © 2014 Planisware 2
  3. 3. After the first day… • 70 trees were planted (the team hit a patch with stones that had to be removed before the trees could be planted) • Total cost was 350 $ (we had to rent a special machine to help remove the stones which cost 147$ for the day) • Simple EVM calculation: – Earned Value = 70 trees planted  2.90$ = 203$ – Budgeted Cost = 100 trees planned per day  2.90$ = 290$ – Actual Cost = 70 trees planted  2.90$ + 147$ for the machine = 350$ © 2014 Planisware 3
  4. 4. Visually… 0 50 100 150 200 250 300 350 400 Start 1st day Actual cost = 350$ Budgeted cost = 290$ Earned Value = 203$ © 2014 Planisware 4

  8. 8. Regarding cost… 0 50 100 150 200 250 300 350 400 Start 1st day EV AC BC © 2014 Planisware 8 Cost variance = EV – AC We’re over budget, and have spent 203  350 = 58% more budget than anticipated (our cost performance index) = 203$ – 350$ = -147$ < 0
  9. 9. Regarding schedule… 0 50 100 150 200 250 300 350 400 Start 1st day EV AC BC © 2014 Planisware 9 We are here

Regarding schedule… 0 50 100 150 200 250 300 350 400 Start 1st day EV AC BC © 2014 Planisware 13 Schedule variance in hours We’re late and have only performed 203/290 = 70% of the work planned (our schedule performance index) = 203$ – 290$ = = -87$ < 0 Schedule variance in dollars = EV – BC
  14. 14. The consequences 0 500 1000 1500 2000 2500 3000 Start 1st 2nd 3rd 4th 5th 6th 7th 8th 9th © 2014 Planisware 14 Earned Value today Estimate at Completion EAC = 3,000$ Budget at Completion BAC = 1,740$ Extending the Actual Cost into the future gives us the end result if we do not modify the performance of the project
  15. 15. The consequences 0 500 1000 1500 2000 2500 3000 Start 1st 2nd 3rd 4th 5th 6th 7th 8th 9th © 2014 Planisware 15 Earned Value today Estimate at Completion EAC = 3,000$ Budget at Completion BAC = 1,740$ Cost Overrun
  16. 16. The consequences 0 500 1000 1500 2000 2500 3000 Start 1st 2nd 3rd 4th 5th 6th 7th 8th 9th © 2014 Planisware 16 Earned Value today Planned end date = 6 days Estimate at completion = 8.57 days Project Slip Estimate at Completion EAC = 3,000$ Budget at Completion BAC = 1,740$ Cost Overrun
  17. 17. The consequences → If we continue at this rate, we will need: 1,740$  58% = 3,000 $ (cost estimate at completion) and 6 days  70% = 8.57 days (schedule estimate at completion) to finish the work. → If we want to finish on budget, we need to work at (planned remaining budget)  (actual remaining budget) (1,740 – 290)  (1740 – 350) = 104.3% of the originally planned performance → If we want to finish on time, we need to work at (actual remaining work)  (planned remaining work) (600 – 70)  (600 – 100) = 106% of the originally planned performance © 2014 Planisware 17
  18. 18. In technical terms… In real life, the elements we calculated have slightly different names: • The Actual Cost is usually referred to as the Actual Cost of Works Performed (ACWP) • The Planned Cost = Budgeted Cost for Work Scheduled (BCWS) • The Earned Value = Budgeted Cost for Work Performed (BCWP) © 2014 Planisware 18
