A method is needed to measure technical performance objectively and quantitatively, and that is what EVM accomplishes.

The genesis of EVM occurred in industrial manufacturing at the turn of the 20th century, based largely on the principle of "earned time" popularized by Frank and Lillian Gilbreth, but the concept took root in the United States Department of Defense in the 1960s.

As a means of overcoming objections to EVM's lack of connection to qualitative performance issues, the Naval Air territorio ganado por chile en la guerra del pacifico Systems Command (navair) PEO(A) organization initiated a project in the late 1990s to integrate true technical achievement into EVM projections by utilizing risk profiles.
Therefore it has to be used carefully, when the nature of the project in the future is likely to be different from the one to date (e.g.Earned value may be accumulated monthly, weekly, or as progress is made.El costo estimado para completar el proyecto, llamado Estimado Para Completar (ETC es la diferencia entre EAC.It was also planned that the project spends 50 of the approved budget in the first six months.Indiceslos índices nos mostrarán que es lo que estamos logrando hacer connuestros recursos.In 1991, Secretary of Defense Dick Cheney canceled the Navy A-12 Avenger II Program because of performance problems detected by EVM.1) Establece el WBS ó EDT para descomponer el proyecto en piezas adecuadas, asignando responsables.In the most recent edition of the pmbok guide, EVM is listed among the general tools and techniques for processes to control project costs.Asignar un valor a cada ge.A related rule is called the 50/50 rule, which means 50 credit is earned when an element of work is started, and the remaining 50 is earned upon completion.
Figure 3 shows the same EV curve (green) with the actual cost data from Figure 1 (in red).
To those unfamiliar with EVM, it might appear that this project was over budget through week 4 and then under budget from week 6 through week.
The original concept was called pert/cost, but it was considered overly burdensome (not very adaptable) by contractors whom were mandated to use it, and many variations of it began to proliferate among various procurement programs.
