# Earned Value Management

Earned value management (EVM)
is a [[project-management]] technique
...

EVM is frequently stated to be capable of
"measuring project performance and progress
_in an objective manner_",[^1]
an analysis that is either optimistic
or totally misleading, depending on the context.

[^1]: [Wikipedia](https://en.wikipedia.org/wiki/Earned_value_management) (emphasis added)

EVM can be an objective measure of _progress_,
but measuring _performance_,
variance of actual cost/hours versus estimated,
(obviously) requires an estimate,
which is subject to bias and error.
