MOD-12 Hantos Paper


As a significant milestone in the DOD’s continuous self-assessment process, the Defense Acquisition Performance Assessment report was released in early 2006. A far-reaching recommendation of the report is the introduction of Time Certain Development as a preferred acquisition strategy, making schedule a Key Performance Parameter. By mandating high confidence cost and schedule estimates, two arms of the well-known “Iron Triangle” (Cost, Schedule, and Performance) become fixed, leaving only requirements in the project management trade-space. The paper’s objective is to offer engineering perspectives and a discussion of the underlying, parametric estimation issues that impact the successful implementation of the report’s recommendation.
