What is an Earned Value Management System (EVMS)?

To implement Earned Value Management (EVM) in an organisation, you need a system that will provide the data, structure, standardisation and calculation methods necessary to compute and monitor the different elements of EVM.

An EVMS therefore is a system that provides the necessary integration between costs, schedule and work scope together with the tools to plan and manage them, establish baselines, track the different cost and performance indicators, and perform analyses and forecasts based on the accumulated data.

Characteristics of an EVMS

To be effective, an EVMS must (among other things) combine the following characteristics:

  • Ability to plan the whole project/program work scope from inception to completion
  • (1) Allow and facilitate the breaking down of the work scope into units of work that can (2) be assigned to people or organisations, (3) identify and track significant dependencies between these units, and (4) relate them to time-phased budgets
  • Objectively and meaningfully measure project/program work progress
  • Work at an appropriate level of detail for tracking project/program data: not so broad that the data becomes meaningless, not so detailed that tracking work progress requires too considerable amounts of time
  • Allow for prompt implementation of corrective or mitigation actions

EVM Standards and Guidelines

The scope of data and processes required to implement EVM means that no two companies will have the same tools and setup.
To help organisations design and implement an effective EVMS, several standards have been published, the most well know of which is ANSI/EIA Standard 748 in the United States. ANSI-748 lays down 32 guidelines, grouped under 5 umbrella topics, that cover the whole of the EVM calculation and monitoring process.

Other project or program management standards include sections on EVM such as DIN 69901 in Germany and BS6079 in the United Kingdom.
Certain government contracts may require the contractor to obtain certification/validation of its EVMS, either by dedicated government agencies such as the Defence Contractors Management Agency (DCMA), other third-parties, or self/peer review, depending on the agency overseeing the contract.
Planisware includes out of the box all the elements required to build a compliant EVMS, and several of our clients have successfully obtained DCMA certification with Planisware as an essential system.
