Project Performance Measurement Earned Value A Starter

  1. 1. 1 Project Performance Measurement - Earned Value Simon Robertson © 2010 Robertson Consulting Ltd June 2010
  2. 2. 2 Benefits of EVM • An up-to-date accurate status of the project • Solid input to proactively make corrections • Allows managing stakeholder expectations • Historic reference for future estimates • No surprises to the customer • More accurate representation of on-time completion © 2010 Robertson Consulting Ltd 2
  3. 3. 3 MSProject 2010 & EVM © 2010 Robertson Consulting Ltd When? Just after you develop the Schedule….. 3
  4. 4. 4 MSProject 2010 & EVM • Important Issue Indicators o Cost overrun – may be working additional hours to keep timeline o Time overrun – may be availability of resources limited o Cost and Time overrun – may be project control, poor quality, rework was necessary © 2010 Robertson Consulting Ltd • Steps to prepare o Ensure all Resources and Materials are in MSProject o Ensure all planning complete and schedule agreed o Establish project baseline from where the variances will be calculated and presented o Add Columns to reflect the EV measures o Prepare project management documents to meet the tracking and reporting requirements from the various project stakeholders o Set expectations with the project team, address any concerns and get buy-in 4
  5. 5. 5 MSProject 2010 & EVM Typical Measures o Planned Value (PV) – amount budgeted to be spent between task’s start date and the status date o Actual Cost (AC) – amount spent while preforming work on a task during a given period o Earned Value (EV) – amount that that should have been spent for a given percentage of work performed on a task © 2010 Robertson Consulting Ltd 5
  6. 6. 6 MSProject 2010 & EVM Typical Variance Metrics oCost Variance(CV) – links spending to earned value CV = EV – AC or BCWP - ACWP oSchedule Variance (SV) – links the work accomplished (earned) with planned SV = EV – PV or BCWP - BCWS © 2010 Robertson Consulting Ltd 6
  7. 7. 7 MSProject 2010 & EVM Typical Performance Indicators o Cost Performance Index CPI = EV/AC or BCWP/ACWP o Schedule Performance Index SPI = EV/PV or BCWP/BCWS o Critical Ratio (?) CR = CPI x SPI or BCWP2/ACWP x BCWS © 2010 Robertson Consulting Ltd 7
  8. 8. 8 MSProject 2010 & EVM Typical Forecasting Metrics o Estimate at Completion (EAC)– apply CPI and SPI as performance factors (PF) o Mathematical EAC (uses PF = 1) EACm = (BAC – EV) + AC or EACm = BAC – CV o Low End EAC (uses PF = CPI) EACL= [(BAC-EV)/ (CPI)] + AC Or EACL = (BAC)/ (CPI) o High End EAC (uses PF = CPI x SPI) EACH = [(BAC – EV)/(CPI x SPI)] + AC © 2010 Robertson Consulting Ltd 8
  9. 9. 9 MSProject 2010 & EVM Typical Cost Corrective Action Metrics o To Complete Performance Index (TCPI) TCPI = (Work remaining)/ (Funds Remaining) o To stay within original BAC TCPI = (BAC – EV) / (BAC – AC) o To stay within newly forecasted LRE where baseline remains at original BAC TCPI = (BAC – EV) / (LRE – AC ) Where LRE (Latest Revised Estimate) LRE (or EACE) = ETC + AC © 2010 Robertson Consulting Ltd 9
  10. 10. 10 MSProject 2010 & EVM Typical Schedule Corrective Action Metrics o To Complete Schedule Performance Index (TCSPI) TCSPI = (Unearned Duration Remaining)/ (Actual Duration Remaining) o To stay within original PMB TCSPI = [PD – (AD)(SPI)] / [(PD - AD)] o To stay within the latest revised Schedule (LRS) where baseline remains at original PMB TCSPI = ([PD – (AD)(SPI)] / [(LRS - AD)] © 2010 Robertson Consulting Ltd 10

  13. 13. 13 Earned Value Useful Notes Main EV measures:  CV = EV – AC (BCWP- ACWP)  SV = EV – PV (BCWP-BCWS)  Above result “0” is on target  CPI = EV/AC (BCWP/ACWP)  SPI = EV/PV (BCWP/BCWS)  CPI, SPI = 1 is on target  CR = CPI x SPI  CR >= 1.0 is good Integrates Scope, Time and Cost • Cost Variance (CV) • Schedule Variance (SV) • Time Variance (TV) • Earned Value (EV = BCWP) • Actual Cost (AC = ACWP) – (if per time = Burn rate) • Planned Value (PV = BCWS) • Budget at Completion (BAC) • Schedule at Completion (SAC) • Cost Performance Index (CPI) • Schedule Performance Index (SPI) • Critical Ratio (CR) 13© 2010 Robertson Consulting Ltd
