How we got the numbers

FedSources Inc., of McLean, Va., compiled Washington Technology’s list of top systems integrators in the state and local market.

Because few companies provide revenue figures for their state and local work, FedSources obtained its information using a variety of sources. Those sources include research and analysis of public-domain information, such as annual reports, Securities and Exchange Commission filings, press releases, and discussions with the companies and other knowledgeable sources in the market.

FedSources, a Washington Management Group company, specializes in providing data-driven research and analysis to companies that do business with the federal and state and local markets.
