In prior audits, GAO has reported that federal agencies faced challenges in developing, implementing, and maintaining their IT investments.

10 All too frequently, agency IT programs have incurred cost overruns and schedule slippages while contributing little to mission-related outcomes. Accordingly, in February 2015, GAO added the government s management of IT acquisitions and operations on its list of high-risk Recognizing the severity of issues related to government-wide management of IT, in 2014, the Congress passed and the President signed federal IT acquisition reform legislation, commonly referred to as the Federal Information Technology Acquisition Reform Act, or This legislation was enacted to improve agencies acquisitions of IT and enable Congress to monitor agencies progress and hold them accountable for reducing duplication and achieving cost savings.
