Book excerpt: This thesis examined cost growth in Department of Defense (DoD) missile systems from 1991 to 2001 using Selected Acquisition Report (SAR) data with a hybrid adjusted cost growth (ACG) model. In addition, an analysis of acquisition reform initiatives during the treatment period was conducted to determine if reform efforts impacted missile system cost growth. A pre-reform (1 January 1991 to 31 December 1996) period and post reform (1 January 1997 to 31 December 2001) period was subjectively developed to compare the mean annual ACG during each period for statistical differences. The hybrid ACG model outlined in this thesis may aid program managers and other interested parties in determining weapon systems cost growth, and the conclusion drawn from analyzing current acquisition initiatives may assist DoD leadership in assessing reform effectiveness on reducing cost growth. This research effort analyzed 135 SARs for 21 missile systems that reported a Milestone II baseline during the treatment period. Adjusted Cost Growth (ACG) calculations revealed that missile systems from 1 January 1991 to 31 December 2001 averaged 28 percent cost growth annually. The acquisition reform analysis included 76 SARs from 20 programs during the pre-reform period and 59 SARs from 13 programs in the post-reform period. A small sample t-test was used to compare the annual means of the two periods and revealed that at a 0.05 significance level, the annual average ACG for the post-reform period was higher than the annual average ACG of the pre- reform period.

Book excerpt: This thesis examined cost growth in Department of Defense (DoD) aircraft weapon systems from 1991 to 2001 using Selected Acquisition Report (SAR) data with a hybrid adjusted cost growth (ACG) model. In addition, an analysis of acquisition reform initiatives during the treatment period was conducted to determine if reform efforts affected aircraft weapon system cost growth. A "pre-reform" (1 January 1991-31 December 1996) period and a "post reform" (1 January 1997-31 December 2001) period were subjectively developed to compare the mean annual ACG during each period for statistical differences. The hybrid ACG model outlined in this thesis may aid program managers and other interested parties in determining weapon systems cost growth, and the conclusion drawn from analyzing current acquisition initiatives may assist DoD leadership in assessing reform effectiveness on reducing cost growth. This research effort analyzed 78 SARs for 13 aircraft weapon systems that reported a Milestone II baseline during the treatment period. ACG calculations revealed that aircraft systems from 1 January 1991 to 31 December 2001 averaged a 40 percent cost growth annually. The acquisition reform analysis included 43 SARs from 11 programs during the pre-reform period and 35 SARs from 7 programs in the post- reform period. A small sample t-test was used to compare the annual means of the two periods. The t-test revealed that there was no significant difference between the annual average ACG for the pre-reform and post-reform periods. The 13 aircraft systems reviewed in this study are as follows: B-1B (Lancer), C130-J (Hercules), C-17 (Globemaster III), KC-135R (Stratotanker), AV-8B (Harrier) AV- 8B (Harrier remanufacture), F-14D (Tomcat), F-16 (Fighting Falcon), F-22 (Raptor), FA-18 E/F (Super Hornet), FA-18 (Hornet), T-6A (JPATS), and the T-45- TS (Goshawk). The thesis methodology, results, and suggestions for future research are provided. (15 tables, 8 figures, 40 refs.)

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 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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Cost growth is a highly visible phenomenon in the procurement of major weapon systems. In general, cost growth is the ratio of a weapon system's current estimate of cost to that of some earlier estimate. Thus, even given the same current estimate, different measures of cost growth are possible, depending on which prior estimate is selected as the baseline. Most studies of cost growth, however, select the cost estimate made at the time of program entry into full-scale development (the development estimate) as the baseline. Both the current estimate and the development estimate are normally taken from the Selected Acquisition Report (SAR), a legally mandated summary report on the status of major acquisition programs. This Note identifies and explains the type of cost data found in the SAR and reviews the history of the SAR with respect to cost reporting. In spite of changes that have improved the quality and comprehensiveness of the data in the SAR, it still presents difficulties for measuring cost growth. Among the most notable problems are failure of some programs to use a consistent baseline cost estimate, exclusion of some significant elements of cost, exclusion of certain classes of major programs, and constantly changing preparation guidelines. Nevertheless, the author concludes that SAR data are suitable for identifying broad-based trends and temporal patterns across a range of programs.

This book was released on 2011-06 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: For nearly 30 years, the statutory provision, known as Nunn-McCurdy (NM), has been an oversight tool for Congress to hold the DoD accountable for cost growth on major defense programs. A NM breach occurs when a program's unit cost exceeds certain thresholds. When that happens, DoD must notify Congress of the breach. There are a number of statutory provisions that help implement cost growth reporting under NM. Referring to these statutory provisions as the NM process, this report examines trends in NM breaches and factors that may be responsible for these trends. It also discusses changes DoD is making or proposing to make to the NM process. Charts and tables. This is a print on demand report.

Available in PDF, EPUB and Kindle. Book excerpt: This study looked at how funding instability affects Army acquisition programs. Most funding instability was found to stem from events external to the Army or ambitious Army-set technical goals. Funding instability's effects took the form of schedule slips, cost increases, and to a lesser degree, technical compromises. No significant association was found between funding instability and the adverse effects of program cost growth and schedule slippage.

Available in PDF, EPUB and Kindle. Book excerpt: Previous RAND Project AIR FORCE work has concluded that the Department of Defense (DoD) and the military departments historically have underestimated the cost of new weapon systems. Analysis of the data in Selected Acquisition Reports (SARs) for a sample of 68 completed programs showed that the average total cost growth (after adjusting for procurement-quantity changes) was 46 percent over the baseline estimate made at Milestone B (MS B) and 16 percent over the baseline estimate made at MS C. The cost growth typically continued for about 75 percent of the time between the initiation of major development and the expending of 90 percent of program funding. Most of the cost growth occurred early in the acquisition phase, and the magnitude of development cost growth at completion for programs initiated in the 1970s, 1980s, and 1990s remained relatively steady. Although quantifying cost growth is important, the larger issue is why cost growth occurs. To answer that question, this analysis examines 35 mature, but not necessarily complete, major defense acquisition programs (MDAPs) from the database of SARs that document the development and procurement of a variety of systems, including aircraft, missiles, electronics systems, launch vehicles, munitions, vehicles, and satellites. The programs were similar in type and complexity to those conducted by the Air Force. We analyzed a relatively small number of programs because of the labor-intensive nature of the work. We first examined the programs as a complete set and then analyzed Air Force and non Air Force programs separately to determine whether the causes of cost growth in the two groups differed.

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 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.
