HELLO ABAS
THIS SIMPLE EVM FORMULA WILL NOT HELP YOU IN FORECASTING THE COMPLETION DATE OF ANY TASK OR WHOLE PROJECT.
P3 FINISH DATE WILL BE ONLY REALISTIC WHEN MOST OF THE LOGIC ARE F-S AND THE PHYSICAL WORK IS GOING AS PER PLAN I MEAN NO OUT OF SCUENCE WORK
SO THERE IS ONLY WAY OUT IS PERFORMANCE BASE ANALYSIS
THIS IS SIMILAER TO EVMA BUT ONE STEP MORE
WE ARE VERY SUCCESSFULLY USUING IT IN OUR PROJECTS
AND I HAVE ALSO USED IT IN DUBAI POWER PROJECT IT WORKS WELL

SPI= (BCWP)/(BCWS) or for each activity (Plan Value) / (Earned Value) or Plan/Actual
in Earned Value Management System :
ETC= ATE/ %C or
ETC= ATE + (OD-ATE*SPI)/SPI or
ETC= OD/SPI
But in P3 Calculations:
ETC = ATE + (1-%C)*OD
SPI: Schedule Performance Index
BCWP: Budgeted Cost of Work Performed
BCWS: Budgeted Cost of Work Scheduled
ATE: Actual Time Expended
%C: % Complete
OD: Original Duration
Hello,
If we are agreed for the relation of 3 variables is
BCWP = SPI x (BQ - ETC)
in my assumption that BCWS = BQ
ACWP = BCWS - ETC
So you have all these 3 variable in P3 Calculation.
Sorry if this comment cannot fulfill your query.
