Cost Estimation and Earned Value Integration

Earned Value Management Track



Traditionally, cost estimators and earned value analysts work separately from one another, focusing on their own individual discipline. We have found synergies by merging these disciplines together resulting in stronger analysis through improved methods, more robust data sets, and new tools. The benefits of cost estimating (CE) and earned value (EV) management integration are realized throughout the acquisition lifecycle and enhance senior leadership decision making and improve acquisition outcomes. This paper presents the proven benefits of CE/EV integration, including more accurate cost estimates, cost estimating relationships, improved program management support, and cross program assessments. We provide the suggested “touch points” between the two capabilities and how they can be enhanced by the other team’s capabilities, tools, and skills, so that analysts can establish and defend more reliable budgets and provide improved compliance and surveillance reviews. Overall, this paper describes how CE and EV teams can increase their functional depth in risk, cost, schedule and technical (scope) analyses.
