The DOD routinely demonstrates its capability to develop phenomenal systems; however, these accomplishments are often tarnished by substantial cost and schedule over-runs. While defense policies are continually being revised to address these problems, many believe that a more fundamental source of these overruns is the lack of flexibility in the sys-tems being developed. But providing justification to invest in flexibility is a tough sell, as stakeholders struggle to quantitatively demonstrate the potential return on investment. There-fore, this paper introduces an alternative methodology for valuing the inherent ability of a system or design to accommodate change. The proposed methodology is essentially a modifi-cation of the current life cycle model and is premised on the notion that the need for capabili-ty changes in a program arise in a stochastic manner that can be incorporated into a continually updated, expected value model presented in terms of total program cost.
