Editing Earned value management (section)

== Scaling EVM from simple to advanced implementations ==
The ''foundational principle'' of EVM, mentioned above, does not depend on the size or complexity of the project. However, the ''implementations'' of EVM can vary significantly depending on the circumstances. In many cases, organizations establish an all-or-nothing threshold; projects above the threshold require a full-featured (complex) EVM system and projects below the threshold are exempted. Another approach that is gaining favor is to scale EVM implementation according to the project at hand and skill level of the project team.<ref>{{cite web
