“EVTA: Earn Value Technique Analysis”:
Sistema de control de coste basado en el valor aportado al avance del proyecto.
Descripción de los Términos e interpretación de Earned Value Management
1.
PV (BCWS) Planned Value: estimated value of the workplanned to be done.
2.
EV (BCWP) Earned Value: estimated value of the work accomplished.
3.
AC (ACWP) Actual Cost: actual cost incurred.
4.
BAC Budget at Completion: How much did you BUDGET for the TOTAL
JOB?
5.
EAC Estimate at Completion: current expected cost of the TOTAL project.
6.
ETC Estimate to Complete: From this point on, how much MORE do we
expect it to cost to finish the job?
7.
VAC Variance at Completion: How much over or under budget do we
expect to be?
Referencias:
Fórmulas:
1.
Cost Variance (CV) EV – AC NEGATIVE is over budget, POSITIVE is under budget
2.
Schedule Variance (SV) EV – PV NEGATIVE is behind schedule, POSITIVE is ahead of schedule
3.
Cost Performance Index (CPI) EV / AC I am [only] getting _____ cents out of every $1.
4.
Schedule Performance Index (SPI) EV / PV I am [only] progressing at ___% of the rate originally planned.
5.
Estimate At Completion (EAC) Note: There are many ways to calculate EAC.
1.
BAC / CPI • Used if no variances from the BAC have occurred
2.
AC + ETC • Actual plus a new estimate forremaining work. Used when original estimate was
fundamentally flawed.
