Work authorisation and project control

3 important questions on Work authorisation and project control

Name the earned value definitions

  • PV - Planned Value (budgeted cost of work scheduled)
  • EV - Earned Value (budgeted cost of work performed or supposed cost)
  • AC - Actual Cost (actual cost of work performed)
  • SV - Schedule Variance (SV = EV - PV)
  • TV - Time variance (SP - Status Date; SP is the date where PV - EV in time units)
  • CV  - Cost variance (CV = EV - AC)
  • Positive variances imply good results

How do you calculate the Performance Index?

SPI = EV / PV

EV: earned value
PV: planned value

SPI > 1 (Ahead of schedule), SPI < 1 (Behind schedule)

How do you calculate the Cost Performance Index?

CPI = EV / AC

EV: earned value
AC: actual cost  

CPI > 1 (Cost saving), CPI < 1 (Over expenditure)
