Book excerpt: The Department of Defense (DOD) is deeply conerned about developing accurate initial estimates for weapon system production costs. An area of particular interest is providing estimates of future production costs for jet engines. Current parametric models used by the Air Force identify engine cost as a function of output variables. Other DOD agencies consider relating input variables as well as output variables to production costs. This study was designed to find a better way to estimate engine production costs. The results of this research include the following findings: (1) current Air Force cost-estimating models are operationally ineffective; (2) raw materials-related variables are highly correlated with cost and should be considered in developing future cost-estimation models; (3) statistical validation of cost models should incorporate confidence interval testing at a specfied alpha level for each prediction; and (4) the use of confidence intervals is the correct statistical approach for developing cost estimates which may be used in decision making.

Book Synopsis The Use of the Maurer Factor for Estimating the Cost of a Turbine Engine in the Early Stages of Development by : Charles W Barrett (Jr)

This book was released on 1979 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Military managers are faced with increasing systems costs. One area where this increasing cost is especially true is in the acquisition of aircraft weapon systems. A driving factor in the aircraft cost is the turbine engine, and therefore acquisition managers have been tasked with developing cost estimating methods that will more accurately predict turbine engine cost. At present, several parametric costing models available are briefly discussed in this report. However, the primary objective of this report, is to evaluate a costing technique used extensively by the Navy--the Maurer Factor (MF) technique. The MF technique is a parametric costing technique based on the materials in a turbine engine. The report includes the following: (a) a detailed description of the MF technique; (b) a validation of the MF technique; (c) the development of an estimated MF (EMF) model using engine performance parameters; and (d) statistical analysis and validation of the EMF models.
Book Synopsis Systems Engineering and Program Management by : David E. Stem
Download or read book Systems Engineering and Program Management written by David E. Stem and published by Rand Corporation. This book was released on 2006 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systems engineering and program management (SE/PM) constitute a large portion of the acquisition cost of military aircraft and guided weapons systems. The goal of this study was the development of a set of cost-estimating relationships that can be used to estimate the SE/PM cost element for development and production of aircraft and weapons programs. The authors canvassed government and industry personnel to learn about current techniques for estimating SE/PM costs, and they collected historical data from several aircraft and weapons programs to investigate trends in SE/PM costs over time and to generate methods that cost analysts can use early in the life cycle of a program when little cost information is available. The authors also investigated the effects on SE/PM costs from acquisition reform, including the reduction in the number of military specifications and standards, the use of integrated product and process teams, and the trend toward "evolutionary acquisition." This product is part of the RAND Corporation monograph series. RAND monographs present major research findings that address the challenges facing the public and private sectors. All RAND monographs undergo rigorous peer review to ensure high standards for research quality and objectivity. Book jacket.
Book Synopsis Is Weapon System Cost Growth Increasing? by : Obaid Younossi
Download or read book Is Weapon System Cost Growth Increasing? written by Obaid Younossi and published by Rand Corporation. This book was released on 2007 with total page 142 pages. 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.
Book Synopsis Historical Cost Growth of Completed Weapon System Programs by : Mark V. Arena
Download or read book Historical Cost Growth of Completed Weapon System Programs written by Mark V. Arena and published by Rand Corporation. This book was released on 2006 with total page 74 pages. 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 Synopsis Sources of Weapon System Cost Growth by : Joseph George Bolten

Available in PDF, EPUB and Kindle. Book excerpt: Previous studies have shown that the Department of Defense (DoD) and the military departments have historically underestimated the cost of new weapon systems. Quantifying cost growth is important, but the larger issue is why cost growth occurs. To address that issue, this analysis uses data from Selected Acquisition Reports to examine 35 mature, but not necessarily complete, major defense acquisition programs similar to the type and complexity of those typically managed by the Air Force. The programs are first examined as a complete set, then Air Force and non-Air Force programs are analyzed separately to determine whether the causes of cost growth in the two groups differ. Four major sources of cost growth were identified: (1) errors in estimation and scheduling, (2) decisions made by the government, (3) financial matters, and (4) miscellaneous sources. Total (development plus procurement) cost growth, when measured as simple averages among the program set, is dominated by decisions, which account for more than two-thirds of the growth. Most decisions-related cost growth involves quantity changes (22 percent), requirements growth (13 percent), and schedule changes (9 percent). Cost estimation (10 percent) is the only large contributor in the errors category. Less than 4 percent of the overall cost growth is due to financial and miscellaneous causes. Because decisions involving changes in requirements, quantities, and production schedules dominate cost growth, program managers, service leadership, and Congress should look for ways to reduce changes in these areas.
