GAO has long reported that agencies are better equipped to address management and performance challenges when managers effectively use performance information for decision making. However, GAO's periodic surveys of federal managers indicate that use of performance information has not changed significantly. GAO was mandated to evaluate the implementation of the GPRA Modernization Act of 2010. GAO assessed agencies' use of performance information from responses to GAO's surveys of federal managers at 24 agencies. To address this objective, GAO created an index to measure agency use of performance information derived from a set of questions from the most recent surveys in 2007 and 2013, and used statistical analysis to identify practices most significantly related to the use of performance information index.
