American Management Systems Inc comes out top in a new survey of US-based IT staffing and services firms from Staffing Industry Analysts, a Los Altos, California-based company. The list ranks companies by IT staffing, project or solutions revenues derived from people-based services within the US last year, and represented $13bn revenues in total. Revenues from software licensing, data center outsourcing and equipment sales were not included. Neither were the Big Six accounting firms, IT consulting firms, large IT outsourcers or software companies providing services only for their own products included, so as to focus the survey more narrowly on IT staffing and services firms, said the authors. Fairfax, Virginia-based American Management made $872m in IT services revenues, followed by AccuStaff Inc at number two with $780m in IT services, 32% of its total revenues. Keane Inc was third with $654m in revenues, followed by Volt Information Services Inc and Metamor Worldwide Inc at numbers four and five. The report predicts further industry consolidation in the sector. The report can be obtained at http://www.itreport.com/
