American Management Systems (previous NASDAQ symbol: AMSY) was a high technology and management consulting firm, founded in 1970 by a group of five former Defense Department officials who had worked under Robert McNamara in the Kennedy and Johnson administration. The company grew throughout the 1980s and 1990s, implementing key systems such as the accounting system for New York City and The Standard Procurement System for the United States Department of Defense. The company was acquired by CGI Group in 2004, with AMS's federal defense business being acquired by CACI.
