A Publication of the Defense Acquisition University

The second article, authored by Gregory A. Davis and David M. Tate and titled, “Complexity in an Unexpected Place: Quantities in Selected Acquisition Reports," notes that the definition of unit quantities in acquisition programs is not consistent (for example, the units produced at the end of a long production run are substantially diferent from the early ones). The authors ofer explanations as to why this is the case, and possible methods for improving the reporting requirement. The third article, "Risk- based ROI, Capital Budgeting, and Portfolio Optimization in the Department of Defense" by JohnathanMun, describes an analytical modeling process to help the U.S. Department of Defense (DoD) senior leadership with making decisions about risk-based capital budgeting and optimizing acquisition and program portfolios.
