Book Description

From the late 1980s through the present, the U.S. Air Force and the U.S. Navy have been acquiring two multirole fighter aircraft platforms. The Air Force has pursued the F/A-22, the world's first supersonic stealth fighter, while the Navy has developed the F/A-18E/F, a carrier-capable fighter with air-to-air, interdiction, and close air support capability. Currently, the F/A-22 is in the late stages of development, while the F/A-18E/F is in full production and has already been deployed in Operation Enduring Freedom and Operation Iraqi Freedom. The design of the F/A-22 includes advancements in all the major areas of the aircraft, including airframe, avionics, and propulsion. The airframe incorporates an advanced stealth design to lower its radar cross section and uses large amounts of advanced materials, such as composites and titanium. The integrated avionics suite of the aircraft brings together information collected from several sensors on the aircraft to be displayed to the pilot. The propulsion system features two high thrust, Pratt and Whitney, F119 jet engines to allow the F/A-22 to supercruise above the speed of sound without using the fuel-consuming afterburner. The airframe design, flight controls, and thrust vectoring are also used to improve the maneuverability of the aircraft. The F/A-18E/F Super Hornet was designed to be an upgrade to the existing F/A-18A/B/C/D multirole aircraft fleet. The programsought to increase the aircraft's range, payload, and survivability. The program was an outgrowth of a Secretary of Defense memorandum from July 1987, directing the Navy to investigate advanced versions of the F/A-18 for 2000 and beyond. The trade studies, known as Hornet 2000, led to a Milestone IV/II review in March 1992 to begin formal Engineering and Manufacturing Development (EMD) of the program in July 1992.

Book Description

How can the Air Force and the other services profit from the experience of these two programs? Although the F/A-18E/F is an upgrade of an existing airframe and the F/A-22 is a new platform, the authors believe their divergent histories have lessons to teach acquisition decisionmakers. The authors present a history of the two programs and conclude that decisionmakers can reduce risk and improve acquisition by taking several steps, including setting realistic schedule and cost estimates and establishing a stable and experienced development team.

Book Description

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 Description

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 Description

Buying defense weapon systems under multiyear contracts rather than a series of single-year contracts can save costs because contractors can buy materials in more economic quantities, schedule workers and facilities more efficiently, and reduce the burden of preparing multiple proposals. The U.S. Air Force is in the process of awarding multiyear contracts for 60 F-22A aircraft over three years. Congress wants to assure itself that the proposed contract will yield the promised savings and asked RAND for an independent review of the estimated savings. Researchers found that a multiyear procurement of three lots of F-22A fighters would save an estimated $411 million-about 4.5 percent of the total contract value. They were able to trace 70 percent of the $411 million to substantiated savings estimates identified by the contractors. Examining the issue of multiyear savings using several approaches produces a consistent range of results, indicating that the savings attributed to the multiyear contract by the contractors appear to be reasonable.

Book Description

Fundamental Economic Principles, Methods, and Tools for Addressing Human Systems Integration Issues and Tradeoffs Human Systems Integration (HSI) is a new and fundamental integrating discipline designed to help move business and engineering cultures toward more human-centered systems. Integrating consideration of human abilities, limitations, and preferences into engineering systems yields important cost and performance benefits that otherwise would not have been accomplished. In order for this new discipline to be effective, however, a cultural change—starting with organizational leadership—is often necessary. The Economics of Human Systems Integration explains the difficulties underlying valuation of investments in people's training and education, safety and health, and work productivity. It provides an overview of how the field of economics addresses these difficulties, focusing on human issues associated with design, development, production, operations, maintenance, and sustainment of complex systems. The set of thought leaders recruited as contributors to this volume collectively provides a compelling set of data and principles for assessing the economic value of investing in people, not just in general but in specific investment situations. The early chapters provide the contexts for HSI and investment analysis, illustrating the enormous difference context makes in how issues are best framed and analyzed. A host of practical methods and tools for investment valuation are then presented. Provided are: A variety of real-world applications of economic analysis ranging from military acquisition and automotive investment to healthcare and high-tech investments in general, in both the U.S. and abroad A range of economics-based methods and tools for cost analysis, cost-benefit analysis, and investment analysis, as well as sources of data for performing such analyses Differing perspectives on economic decision-making, including a range of private sector points of view, as well as government and regulatory perspectives In addition, five real-world case studies illustrate how such valuations have been done and their major impacts on investment decisions. HSI professionals, systems engineers, and finance professionals who address investment analysis will appreciate the wide range of methods and real-life applications; senior undergraduates and masters-level graduate students will find this to be an excellent textbook that provides theory and supports practice.

Book Description

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.

Book Description

Risk, Opportunity, Uncertainty and Other Random Models (Volume V in the Working Guides to Estimating and Forecasting series) goes part way to debunking the myth that research and development cost are somewhat random, as under certain conditions they can be observed to follow a pattern of behaviour referred to as a Norden-Rayleigh Curve, which unfortunately has to be truncated to stop the myth from becoming a reality! However, there is a practical alternative in relation to a particular form of PERT-Beta Curve. However, the major emphasis of this volume is the use of Monte Carlo Simulation as a general technique for narrowing down potential outcomes of multiple interacting variables or cost drivers. Perhaps the most common of these in the evaluation of Risk, Opportunity and Uncertainty. The trouble is that many Monte Carlo Simulation tools are ‘black boxes’ and too few estimators and forecasters really appreciate what is happening inside the ‘black box’. This volume aims to resolve that and offers tips into things that might need to be considered to remove some of the uninformed random input that often creates a misinformed misconception of ‘it must be right!’ Monte Carlo Simulation can be used to model variable determine Critical Paths in a schedule, and is key to modelling Waiting Times and cues with random arisings. Supported by a wealth of figures and tables, this is a valuable resource for estimators, engineers, accountants, project risk specialists as well as students of cost engineering.
