This week, IDC Government Insights announced the results of its 2017 IDC Government Top 50 Vendor Rankings. These rankings use a standardized methodology to publish the estimated IT revenue of the top vendors serving the U.S. federal government. IDC examines thousands of different federal IT contracts, and then isolates the spending by fiscal year. We send our estimates to the companies for their consideration and potential feedback.
These numbers focus strictly on estimated revenue from the sale of hardware, software and IT services. The numbers do not include things like staffing costs, business process engineering, or other non-IT spending. This approach is unique to IDC. It makes our numbers lower than what can be seen on other government top IT vendor lists, but we believe this approach is a better measure of what is truly "addressable" IT spending by the federal government.
These Top 50 rankings reinforce the benchmarks laid down last year in the inaugural version of this effort. For over 50 years, IDC has collected and analyzed IT industry data. This annual effort focuses on the Top 50 IT vendors who mainly serve the government market. But we also create an "Enterprise Top 25" list - which ranks the largest IT vendors that serve multiple industries. (The rankings are mutually exclusive.)
The two categories of the government IT vendor rankings are as follows:
The Top 50 features the largest companies that derive more than one-third of their revenue from U.S. federal government business. The top 5 companies on this year's top 50 list are:
- Lockheed Martin
- Northrop Grumman Systems
- §attelle Memorial Institute
The Enterprise Top 25 features the largest companies that serve many different industries, and which derive less than one-third of their revenue from U.S. federal government business. The top 5 companies on this year's top 25 enterprise list are:
- Science Applications International Corporation
- Level 3 Communications
