materials, controls, and numerous other areas that have translated into countless performance and economic gains. In very fluid domains, such as missile defense or net-centric war- fare, where basic concept architecture is not yet fixed, the incremen- tal methods used in IHPTET and other engine programs may not achieve the success experienced in the turbine engine research pro- grams. IHPTET methods appear to be more applicable to systems acquisition programs in the spiral development phase. Such meth- ods include the goals, objectives, challenges, and actions (GOTChA) process, which develops quantitative, phased goals for technologi- cal advancement. The GOTChA process works well for incremental programs where goals and objectives can be applied to development of technologies for existing systems architectures. It is less clear that blue sky, first principles’ basic research will lend itself readily to this more structured approach, or that it will support architecture design and systems-of-systems concepts. In other words, the less well-defined the concept, the less the IHPTET model applies. The extent to which the GOTChA process from IHPTET can apply to less well-defined research programs depends on the ability to define quantifiable goals as part of the exercise. The IHPTET planning process and model applies to the highest mission goals that can be quantified and, thus, verified. In very novel system design areas, such as network centric warfare or missile defense, goals may be hard to quantify at the system architecture level. The question in such programs is if it will work rather than how much, Still, IHPTET methods may work well on subsystems or components such as interceptor missile guidance systems. Robert Henderson summarizes the impact of IHPTET in this way: Continual Pentagon oversight and interest by Dr. Donald Dix was particularly important throughout each year since the initiation of IHPTET in 1987, and, although painful at times, did much to keep the IHPTET program on track and focused on its long-term goals. IHPTET was often referred to as a revolutionary technology development program because of its aggressive goal of doubling propulsion system performance and operational capability in about 12–15 years. In fact, I would say it was an aggressive evolutionary technology program that resulted in a more accelerated technology development, demonstration, and transition of a number of key turbine engine technologies. Without the continual and dedicated focus of IHPTET by both government and industry during the past 15 years, progress in turbine engine capability would definitely have evolved at a much slower pace. Both commercial and military aircraft systems realized advanced capabilities many years sooner as a result of the work accomplished under IHPTET. Acknowledgments The authors thank the Missile Defense Agency of the U.S. De- partment of Defense, which funded this research at the Institute for Defense Analyses. Richard Van Atta led the technology man- agement program under which this research was conducted. Also, Belcan Corporation generously arranged and supported a workshop at their headquarters to explore the issues. Attending the workshop were R. Atcheley, L. Burns, P. Combs, T. Curran, M. Eismeier, J. Fischer, J. Henderson, G. Knight, H. Maclin, J. Reed, and the authors. The authors interviewed a number of current and retired personnel from both the U.S. government (laboratory personnel to officials in the Pentagon) and the large engine companies (General Electric Aircraft Engines; Pratt and Whitney, United Technologies Corporation; Rolls–Royce, plc.; and others). The authors would like to acknowledge a debt to L. Burns, L. Coons, D. Dix, T. Donohue, D. Edmunds, D. Gissendanner, W. Heiser, R. Henderson, R. Hill, A. Martino, J. Nelson, R. Nelson, R. Standahar, R. Weiss, and J. Williams, who provided white papers and participated in extensive interviews. References 1Koff, B.
