Contract Over Target Baseline (OTB) Effect on Earned Value Management's Cost Performance Index (CPI)
Abstract : Cost growth is a problem in U.S. Department of Defense (DoD) acquisitions. A particular component of cost growth is a cost overrun or Over Target Baseline (OTB). In 2009, Trahan found that the Gompertz growth curve better predicted program Estimates at Completion (EAC) for OTB contracts. In 2010, Thickstun studied "the relationships between overruns and a variety of factors," but found OTB occurrences "random" and questioned the benefit of the OTB process (Thickstun, 2010). In this research, we study OTB's ability to effect improved program cost performance; we examine OTB's effect on the cumulative Cost Performance Index (CPI) slope after an OTB intervention. We find there is no statistically significant change in cumulative CPI slope after OTB. For the data studied, an OTB investment does not significantly improve management's ability to earn cost value as reflected in the cumulative CPI slope.
An Analysis of the Implementation of Acquisition Reform Initiatives and Contract Cost Variance
Abstract : This thesis examines the impact of acquisition reform initiatives implemented since 1993 on contract cost performance. Many initiatives implemented during the 1990s focused on saving the government money in procuring weapon systems. For decades, cost overruns have plagued Department of Defense weapons systems development and procurement costing the government money. The passage of the Federal Acquisition Streamlining Act (FASA) of 1994 and the Clinger-Cohen Act of 1996, marked significant congressional action on aiding the Department of Defense develop and procure systems cheaper. Conclusions drawn in this thesis may aid leadership in supporting current initiatives and drafting new changes.
Rapid determination of the effectiveness of insect resistant packaging
A technique was developed to evaluate the usefulness of odour barriers and to determine the effect of package content in consumer size packages on resistance to infestation by insects. Female Plodia interpunctella (Hubner) could distinguish sealed packets containing food from non-food items as a suitable site for oviposition. Utilization ofthis technique will reduce the time needed to evaluate new materials for use in insect resistant packaging.
