GAO said in a report to Congress published this month that approximately $2 billion was from data center consolidation and optimization, while the Social Security Administration and Defense, Homeland Security and Treasury departments accounted for $2.5 billion.
The report also noted that 22 federal agencies did not fully implement OMB’s guidance on plans to reinvest the achieved savings, while others did not track the performance or results of their reinvestment efforts.
GAO urged agencies to complete their reinvestment plans and called on OMB to require the tracking of reinvestment performance and define targets beyond fiscal year 2014.
