Bush administration career prior to EPA
Before working at EPA, Mr. Peacock was an associate director at the U.S. Office of Management and Budget (OMB).
While at OMB, Mr. Peacock created the Performance Assessment Rating Tool, or PART, which was used to rate the effectiveness of federal programs. The PART won Harvard University's Innovations in Government Award in 2005 and the American Society for Public Administration's Leadership Award in 2007. During this time, Mr. Peacock also helped develop a performance-based system for funding U.S. Army Corps of Engineers' projects and for this work, in 2006, was awarded the Army's Outstanding Civilian Service Medal.
EPA deputy administrator
During his tenure Peacock overhauled EPA's performance management system. This included publishing a quarterly performance report to the public called the EPAStat Quarterly Report, the first 'Stat' program in the federal government. EPAStat copied performance management systems used by local governments, such as "CitiStat" in the City of Baltimore. These improvements led to EPA winning the President's Quality Award for Overall Management, "the highest award given to federal agencies for management excellence," in 2007 and 2008. It is the first time a federal agency has won the award back-to-back. Peacock was an early adopter of Web 2.0 technology in government and was the first federal political appointee to maintain a public blog.
The Pew Charitable Trusts Under a two-year contract with the Pew Charitable Trusts from 2009 to 2010, Peacock directed Subsidyscope, an initiative to collect data on subsidies provided by the U.S. government and make this information available to the public.
Jeb Bush 2016 campaign During Governor Bush's presidential campaign, Peacock served as Bush's deputy director for policy and assisted in directing a group of policy experts. As part of his role at the Regulatory Studies Center he writes articles and public comments on regulatory policy and relevant political events.
