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 https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-07-498/html/GAOREPORTS-GAO-07-498.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-07-498/pdf/GAOREPORTS-GAO-07-498.pdf GAO-07-498 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-07-498 Other Written Product GAO-07-498; Polar-Orbiting Operational Environmental Satellites: Restructuring Is Under Way, but Technical Challenges and Risks Remain; Contract modifications Cost analysis Cost control Cost overruns Earth resources satellites Federal procurement Interagency relations Procurement planning Program evaluation Program management Risk assessment Schedule slippages Strategic planning Work measurement Cost estimates Cost growth Policies and procedures National Polar-Orbiting Operational Environmental Satellite System Public Law 109-163 Public Law 109-364
