Abstract:

A shrinking workforce, unstable budgets, and rapidly changing objectives under stricter time constraints characterize todays cost analysis and acquisition environment. In concert with this environment, cost analyst positions have rapidly decreased as demonstrated by Aeronautical Systems Centers 54 decline in total authorized slots from 1992 to 2001. The question is how to deal with this more with less mentality. The purpose of this research is to investigate and measure the risks associated with taking a macro versus micro approach to aircraft cost estimation. By analyzing the fidelity of a cost estimate developed at the flyaway cost level versus a cost estimate developed at the individual components level, this research provides guidelines for appropriate allocation of cost analyst resources, This objective is accomplished by looking at the cost estimation error risk of recurring costs at level one of the Work Breakdown Structure WBS and at level two of the WBS, Results show that there is a statistically significant difference between estimating at the differing WBS levels, However, from a practical standpoint, the difference in dollar terms is too small to be considered significant, As a result, program manager should allocate resources based on other constraints such as time allotted to complete the estimate or required level of visibility into the estimate
