Recurring problems in managing its programs and projects plagued the Dept. of Energy (DoE) to such a degree in the late 1980s and early 1990s that by 1995, DoE responded to calls for restructuring by initiating "unprecedented" reforms that it said would "fundamentally improve the efficiency and effectiveness of the department." This report: (1) describes actions taken by DoE to improve its performance in the early to mid-1990s; (2) assesses DoE progress since then in addressing management weaknesses and improving performance; and (3) identifies any underlying impediments to more effective management and improved performance at DoE.
