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



FOR FURTHER INFO

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.
