AMERICAN MANAGEMENT SYSTEMS

'American Management Systems' () was founded in 1970 as a technology and management consulting firm. It was founded by a group of five former United States Department of Defense officials who worked under Robert McNamara in the Kennedy and Johnson administrations. The company grew to a size greater than nine thousand workers, with many offices in both the United States and other countries. At one point in the 1990s, one quarter of the company's revenue, albeit none of the profit, came from Europe. Much of its business was creating large computer systems for various government entities. It created a large accounting system for New York City during its recovery from its fiscal crisis in the late 1970s.
For the first 20+ years of its existence, the company was based in Arlington, Virginia on the banks of the Potomac River with a commanding view of Washington DC. In the early 1990s, AMS moved its corporate headquarters to Fairfax, Virginia. By the late 1990s, all AMS offices in Arlington were vacated and all D.C.-area personnel (approximately half of the worldwide staff) were based in Fairfax.
In 2004, several factors, most notably an inattentive Board Of Directors, a series of ineffective CEOs, and the senior executives' overall inability to adapt to new business models, combined to force it to be sold. (It had already sold its Global Energy Group to Bangalore, India-based Wipro Technologies () in December 2002.) CGI, a Canadian company, was the primary purchaser, getting the commercial business and all government business not related to national defense. The defense portion of AMS could not be sold to a company based outside the U.S. so that part of AMS was purchased by CACI. The AMS brand was retained by CGI and the AMS website will direct users to the CGI site. CGI's United States headquarters are in Fairfax, Virginia.
AMS in Europe. In 1992 AMS was in a unique position to provide the young mobile telco market in Europe with a billing system (Tapestry) making AMS one of the major players in the European Market. Despite this success, the company did not develop sufficient service delivery and business development units which was one of the effects that led to significant layoffs in Europe in 2002.
In 2002, AMS had approximately 6300 employees, 986 million in revenue and 21 million in income and 51 offices worldwide.
