Beyond Cost-Per-Unit: Economic Analysis and Metrics in Defense Decisionmaking, (Paperback)

This report presents the strengths and limitations of cost-effectiveness analysis and related metrics to inform the U.S. Army about whether, when, and how to usefully employ them for capability investment decisions. The authors discuss how complexity can increase as objectives become less clear cut, ancillary benefits and unintended consequences emerge, technologies become intertwined, boundaries change, and risk and uncertainty take hold.
