Book excerpt: The 'managing for results' movement that began in the early 1990s has now reached adolescence and is creating new challenges for government managers. After spending years creating planning and performance-measuring systems, managers and policy makers now need to focus on how to use performance information to make data-driven decisions. Managing Results for 2005 describes--through a series of case studies--the progress being made in federal, state, and local governments in managing for results. Part I increases our understanding about the potential use of performance information in government. It starts with a chapter on how government leaders can overcome obstacles to using performance information. Another chapter presents a comprehensive framework for tying performance to the budget process. The book provides specific examples of how performance information has been used to dramatically improve program outcomes. Part II presents case studies on the use of performance information to improve results in a range of federal agencies, in Texas state government, and in the City of Baltimore. As pioneering efforts, these examples do not all present success stories; nevertheless, the lessons learned will be instructive to public managers as the 'managing for results' movement advances toward maturity.
