earned-value-management 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.
EVM can be argued to be an objective measure of progress, but measuring performance, variance of actual cost/hours versus estimated, (obviously) requires estimates, which are subject to bias and error. If you argue that subject matter expert estimates are objective under a Bayesian interpretation, then sure, but then EVM is not unique.
EVM WBS's, as a form of estimate-decomposition, suffer from its weakness of compounding inaccuracy.
