The introduction of advanced manufacturing technology in the aerospace industry poses serious challenges for government cost analysts. Traditionally, these analysts have relied on parametric estimating techniques for both planning and budgeting. Despite its problems, this approach has proven to be a remarkably useful and robust tool for estimating new weapon system costs. However, rapid improvements in both product and process technology could exacerbate current difficulties and diminish the utility of the parametric approach. This paper reviews some weaknesses associated with parametrics, then examines how specific aspects of the factory of the future may further affect parametric estimating. Finally, it suggests avenues of research.

This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
