A letter report issued by the Government Accountability Office with an abstract that begins "Each year the federal government spends billions of dollars on information technology (IT) investments. Given the importance of oversight, the Office of Management and Budget (OMB) established a public Web site, referred to as the IT Dashboard, that provides detailed information on about 800 federal IT investments, including assessments of actual performance against cost and schedule targets (referred to as ratings). In the second of a series of Dashboard reviews, GAO was asked to (1) determine OMB's efforts to improve the Dashboard and how it is using data from the Dashboard, and (2) examine the accuracy of the Dashboard's cost and schedule performance ratings. To do so, GAO analyzed documentation on OMB oversight efforts and Dashboard improvement plans, compared the performance of 10 major investments from five agencies with large IT budgets against the ratings on the Dashboard, and interviewed OMB and agency officials."
