FEDSIM now outsources most of the work and has expanded its business lines from computer performance evaluation to include anything in information technology (IT) plus professional services.

FEDSIM's increasing reliance on the private sector is consistent with the current Government policy of contracting out tasks that are not an "Inherently Governmental Function".

Because of Government regulations, agencies often needed to open their computer acquisitions to a variety of manufacturers; the Conversion Support Center analyzed the cost to convert software from one vendor architecture to another in that situation.

Large and long-running FEDSIM projects from the 80s and up to the present have included IT support of ADNET,[15] a multi-agency Anti-Drug Network; development of the Internal Revenue Service’s Electronic Filing system E-file; purchase of scientific computers for the National Institutes of Health; program management support to JIDA, the Defense Department’s Joint Improvised-threat Defeat Agency; and multi-faceted system integration projects for the Agency for International Development, the Federal Deposit Insurance Corporation, and others.

It establishes an Integrated Project Team that manages the procurement from requirements gathering to award and through to the end of the performance period.

FEDSIM offers innovative, dedicated approaches to acquisition resulting in cost savings and higher quality goods and services.

[22] For example, over the last 10 years, FEDSIM has provided its agency clients with emerging methods and technologies like server virtualization and cloud computing; commercial off-the-shelf COTS software for system development with enterprise products like SAP and in niche areas like insurance underwriting; social media and mobile technologies; and others.

FEDSIM has expanded the breadth of its offerings in professional services like logistics or to meet unique needs such as strategic weapon system planning and policy making for the Air Force.
