Estimate-At-Completion Research - A Review and Evaluation

Abstract

This research derives from the Performance Measurement discipline and consists of a comprehensive analysis of Estimate-At-Completion (EAC) studies published since 1973. The EAC studies consisted of models, comparison studies, and computer analysis programs. Each study was categorized by formula type and described in terms of methodology and conclusions. Each study was evaluated based on clarity, documentation, methodology, and source. After reviewing the studies some areas were found to be weak. The AFSC formula that uses weighted percentages of .2 SPI and .8 CPI, is not supported by a critical review of the literature. In the area of comparisons studies, different past performance factor formulas have been compared with respect to different percent completion points, type of contract, and type of product. Little work has been done comparing regression formulas to past performance factor formulas. An important outcome of this research identified the scarcity of formal EAC theory or relevant research concerning the underlying causes of 'Why' certain EAC formulas are better predictors of performance.
