Summary: GAO's Performance and Accountability Series outlined the major management challenges confronting the largest federal agencies and discussed opportunities to improve their performance. (See GAO/OCG-99-22SET, Jan. 1999.) Many of these challenges involve longstanding, difficult problems that will not be quickly or easily solved. In fact, sustaining major changes will require a cultural transformation at many agencies. Success in overcoming problems of this magnitude often depends, at least initially, on whether an agency has a well-thought-out management improvement initiative to guide its reform efforts. This testimony discusses six elements that GAO believes are crucial to ensuring that management improvement initiatives truly take root and solve the problems they are intended to fix. These elements are (1) a demonstrated leadership commitment and accountability for change; (2) the integration of management improvement efforts into programmatic decisionmaking; (3) thoughtful and rigorous planning to guide decisions, particularly to address human capital and information technology issues; (4) employee involvement to elicit ideas and build commitment; (5) organizational alignment to streamline operations and clarify accountability; and (6) strong and continuing congressional involvement.
