Improved Operational Testing and Evaluation: Better Measurement and Test Design for the Interim Brigade Combat Team with Stryker Vehicles. Phase I Report. Panel on Operational Test Design and Evaluation of the Interim Armored Vehicle, Committee on National Statistics. Wash- ington, DC: The National Academies Press. The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council. www.national-academies.org PANEL ON OPERATIONAL TEST DESIGN AND EVALUATION OF THE INTERIM ARMORED VEHICLE STEPHEN M.

The Panel on Operational Test Design and Evaluation of the Interim Armored Vehicle has been charged with a less common task: providing an assessment and review of an ongoing activity, the operational testing of an important military system. The procedures for the extremely complex and highly sensitive testing, which has yet to be carried out, are specified in the Army’s system evaluation plan (SEP) for the Stryker family of vehicles. Both the panel and our sponsor acknowledge that the SEP is a “living document” (or moving target); this has already been manifest by the study’s being overtaken by a number of events during the 11 months of the panel’s tenure: • The Interim Armored Vehicle (IAV) in the panel’s initial (and offi- cial) name and statement of work has been renamed the Stryker family of vehicles. • The Interim Brigade Combat Team (IBCT) concept, for which the Stryker is intended to provide mobility and “situation awareness” support, has been continuously evolving. ix
