Source-derived summary

American Management Systems, Inc., 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 Canada's CGI Inc. in 2004, with AMS's federal defense business being acquired by CACI.

History

AMS was founded in 1970 by five former Defense Department "Whiz Kids": Charles Rossotti, Ivan Selin, Frank Nicolai, Patrick W. Gross, and Jan Lodal. The company's initial headquarters were in the Washington, D.C. suburb of Arlington, Virginia. The founders drew upon research in attribute-value systems and early relational databases developed by Pentagon colleague Hugh Everett III, who served as a non-administrative vice president and minority partner in the firm for a time. From its inception, much of AMS's revenue was derived from contracts with federal agencies. The company grew quickly during the 1970s. During its first decade of operation, AMS focused its business on consulting and selling customized software to large government and corporate organizations.

The company grew to over nine thousand employees, with many offices in both the United States and other countries.

Editorial analysis

Why this record matters

The phrase “american consulting firm” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
