Cost estimating relationship associating engineering drawing quality with installation cost growth for USN ship alterations

This is an analysis of existing feedback in the Fleet Modernization Program (FMP) planning and design process using the FFG-7 class of ships as a case study. This analysis attempts to relate the engineering drawing revision rate (inverse measure of drawing quality) and the number of ships affected by those drawing revisions (measure of availability concurrence) to the cost growth attributable to the FMP portion of U.S. Navy ship availabilities. Due to the lack of actual cost data, budget estimates were used as a surrogate and unfortunately firm relationships could not be established. However, the methodology developed has potential for application to any large ship class which may experience numerous concurrent availabilities, as actual cost data become available. It is meant to be a tool for the engineering design agent to assess the financial impact of the quality of engineering design products on the installing activities and to assess the potential value of policy changes which improve the quality of those products.
