Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, there have been numerous attempts to rein in the cost growth of U.S. Department of Defense (DoD) acquisition programs. Cost growth is the ratio of the cost estimate reported in a program's final Selected Acquisition Report (SAR) and the cost-estimate baseline reported in a prior SAR issued at a particular milestone. Drawing on prior RAND research, new analyses of completed and ongoing weapon system programs, and data drawn from SARs, this study addresses the following questions: What is the cost growth of DoD weapon systems? What has been the trend of cost growth over the past three decades? To address the magnitude of cost growth, it examines cost growth in completed programs; to evaluate the cost growth trend over time, it provides additional analysis of a selection of ongoing programs. This sample of ongoing programs permits a look at growth trends in the more recent past. Changes in the mix of system types over time and dollar-weighted analysis were also considered because earlier studies have suggested that cost growth varies by program type and the cost of the program. The findings suggest that development cost growth over the past three decades has remained high and without any significant improvement.

Available in PDF, EPUB and Kindle. Book excerpt: This report is one of a series from a RAND Project AIR FORCE project, "The Cost of Future Military Aircraft: Historical Cost Estimating Relationships and Cost Reduction Initiatives." The purpose of the project is to improve the tools used to estimate the costs of future weapon systems. It focuses on how recent technical, management, and government policy changes affect cost. This report focuses on the accuracy of cost estimates. For our analysis, we used a very specific sample of Selected Acquisition Report (SAR) data, namely only programs that are complete or are nearly so. The analysis indicates a systematic bias toward underestimating the costs and substantial uncertainty in estimating the final cost of a weapon system. In contrast to the previous literature, the cost growth was higher than previously observed. We also found few correlations with cost growth, but observed that programs with longer duration had greater cost growth and electronics programs tended to have lower cost growth. Although there were some differences in the mean cost growth factors among the military departments, the differences were not statistically significant. While newer programs appear to have lower cost growth, this trend appears to be due to factors other than acquisition policies.

Book excerpt: Cost growth in weapon system development, one result of the inherent risk of developing advanced systems, has been a prevalent problem for many years. A systematic bias in cost estimates can undermine the basis of resource allocation decisions, an important problem in a tight budget environment. Currently DoD is in this situation. This exploratory research attempts to gain new insight into this old acquisition issue. In particular, our objectives were to quantify the magnitude of cost growth in weapon systems, and identify factors affecting cost growth. A better understanding of the scope of the cost growth problem would provide decisionmakers with an improved basis for mitigating cost growth. Insight into the drivers of cost growth might suggest policy alternatives appropriate to the goal of mitigating cost growth. This research uses a database composed of 197 major weapon systems reporting through the Selected Acquisition Report (SAR) process as of December 1990 to address these issues. While we have quantified the magnitude of weapon system cost growth along a number of dimensions, we could not definitively account for the observed cost growth patterns. Thus, no silver bullet policy option is available for mitigating cost growth.

Available in PDF, EPUB and Kindle. Book excerpt: This analysis uses data from Selected Acquisition Reports to determine the causes of cost growth in 35 mature major defense acquisition programs. Four major sources of growth are identified: (1) errors in estimation and scheduling, (2) decisions by the government, (3) financial matters, and (4) miscellaneous. The analysis shows that more than two-thirds of cost growth (measured as simple averages) is caused by decisions, most of which involve quantity changes, requirements growth, and schedule changes.

Book excerpt: This report is one of a series from a RAND Project AIR FORCE project, "The Cost of Future Military Aircraft: Historical Cost Estimating Relationships and Cost Reduction Initiatives." The report complements another document from this project, "Impossible Certainty: Cost Risk Analysis for Air Force Systems," and includes a literature review of cost growth studies and a more extensive analysis of the historical cost growth in acquisition programs than appears in the companion report. Overall, most of the studies reviewed reported that actual costs were greater than estimates of baseline costs. The most common metric used to measure cost growth is the cost growth factor (CGF), which is defined as the ratio of the actual cost to the estimated costs. A CGF of less than 1.0 indicates that the estimate was higher than the actual cost -- an underrun. When the CGF exceeds 1.0, the actual costs were higher than the estimate -- an overrun. Studies of weapon system cost growth have mainly relied on data from Selected Acquisition Reports (SARs). These reports are prepared annually by all major defense acquisition program (MDAP) offices within the military services to provide the U.S. Congress with cost, schedule, and performance status. The comparison baseline (estimate) typically corresponds to a major acquisition decision milestone. Prior studies have reported Milestone (MS) II CGFs for development costs ranging from 1.16 to 2.26; estimates of procurement CGFs ranging from 1.16 to 1.65; and total program CGFs ranging from 1.20 to 1.54. Regarding the differences among cost growth due to service, weapon, and time period, prior studies tended to find the following: Army weapon systems had higher cost growth than did weapon systems for the Air Force or Navy; cost growth differs by equipment type; and cost growth has declined from the 1960s and 1970s, after it was recognized as an important problem.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis quantitatively analyzes the factors that affect weapon system cost growth after Milestone 2. The data from nine weapon systems was reconstructed by the Army and Navy from Selected Acquisition Reports (SARs) with the cost variances reclassified into a new categorization system to more readily determine the causes of cost growth. Each cost variance was classified as to whether it was attributable to a mistake in the cost estimating process or a post-Milestone 2 decision, with further classification into subcategories for a more detailed analysis. The cost variances were divided by the Milestone 2 Decision Estimate (DE) to form a cost growth ratio (CGR). The findings reveal that the Department of Defense has about 10.8% cost growth in the procurement process. Cost growth due to decisions outweigh mistakes by a factor of 2.3:1. A majority of the mistake cost growth is due to errors in the estimation of production costs. A majority of the decision cost growth is due to schedule slippage. Low cost systems have 2.4 times as much mistake cost growth as high cost systems. Newer missile systems have significantly less mistake cost growth when compared to other systems. Lastly, the Army and Navy have approximately equal cost growth on their newer systems. Cost.

Available in PDF, EPUB and Kindle. Book excerpt: Much attention has been placed on cost growth in military weapon system acquisitions. The reasons for cost growth can be related to uncertainty relative to program costs, delivery dates and product reliability. A conceptual model has been developed to cope with the uncertainties in weapons acquisition programs. The model relates the concepts of entropy, information, uncertainty and costs, predicting final costs based on a measure of uncertainty, synonymous with risk in this study. The measure of uncertainty is entropy, or the lack of order in the information available to the program manager. The model expresses final costs as the ratio of initial cost estimates to program entropy. The authors develop and refine the model for application to weapon development programs.
