Earned Value Management (EVM)Add to favorites
Earned Value Management (EVM) (see Earn Value Management Section) is a project management technique for measuring project performance and progress in an objective manner. EVM has the ability to combine measurements of scope, schedule, and cost in a single integrated system. It’s notable for its ability to provide accurate forecasts of project performance problems. Early EVM research showed that the areas of planning and control are significantly impacted by its use; and similarly, using the methodology improves both scope definition as well as the analysis of overall project performance. 
EVM is a key integrating process in the management and oversight of acquisition programs, to include information technology projects. It is a management approach that has evolved from combining both government management requirements and industry best practices to ensure the total integration of cost, schedule, and work scope aspects of the program. Unless waived by the Milestone Decision Authority (MDA), EVM applies to contracts described below. The program manager’s approach to satisfying the EVM requirement for applicable contracts should be documented in the program Acquisition Strategy. 
The requirement for EVM applies to cost or incentive contracts, subcontracts, intra-government work agreements, and other agreements that meet the dollar thresholds prescribed in DoD Instruction 5000.02. The application thresholds (total contract value including planned options in then-year dollars) are summarized below: 
- $20 million but less than $50 million – EVM implementation compliant with the guidelines in ANSI/EIA 748 (available for purchase) is required. No formal EVMS validation is required.
- $50 million or greater – EVM implementation compliant with the guidelines in ANSI/EIA 748 is required. An EVM that has been formally validated and accepted by the cognizant contracting officer is required.
EVM is an important tool used by Program Managers (PM) and Systems Engineers in the Technical Assessment Process to appraise the program technical progress against the Performance Measurement Baseline (PMB). Systems Engineering is responsible for characterizing the entire technical scope of effort in the Work Breakdown Structure (WBS) and the corresponding event driven program implementation in the Integrated Master Schedule (IMS). The WBS and IMS form the basis of the PMB and the foundation of EVM.
