【 摘 要 】

These factors led to a June 2006 decision to restructure the program thereby decreasing the program's complexity, increasing its estimated cost to $12.5 billion, and delaying the first two satellites by 3 to 5 years. GAO was asked to (1) assess progress in restructuring the acquisition, (2) evaluate progress in establishing an effective management structure, (3) assess the reliability of the cost and schedule estimate, and (4) identify the status and key risks facing the program's major segments. To do so, GAO analyzed program and contractor data, attended program reviews, and interviewed program officials"
