This article shows a reusable, extensible, adaptable, and comprehensive
advanced analytical modeling process to help the U.S. Department of Defense
(DoD) with risk-based capital budgeting and optimizing of acquisition and
program portfolios with multiple stakeholders while subject to budgetary,
risk, schedule, and strategic constraints. The article covers traditional
capital budgeting methodologies in industry and explains how these
methods can be applied in the DoD by using DoD-centric, noneconomic,
logistic, readiness, capabilities, and requirements variables. Portfolio
optimization for the purposes of selecting the best combination of programs
and capabilities is also addressed, as are alternative methods such as
average ranking, risk metrics, lexicographic methods, PROMETHEE,
ELECTRE, and others. Finally, an illustration from the Program Executive
Office Integrated Warfare Systems (PEO-IWS) and Naval Sea Systems
Command (NAVSEA) showcases the methodology’s application in developing
a comprehensive and analytically robust case study that senior leadership
at the DoD may utilize to make optimal decisions.
