Current State of Federal Information Technology Acquisition Reform and Management [Updated July 10, 2019] [open pdf - 1MB]
From the Summary: "The Government Accountability Office (GAO) has reported that the federal government budgets more than $80 billion each year on information technology (IT) investments and in FY2017, GAO estimates that this investment will increase to more than $89 billion. Historically, the projects supported by these investments have often incurred 'multi-million dollar cost overruns and years-long schedule delays.' In addition, GAO has reported that these projects may contribute little to mission-related outcomes and, in some cases, may fail altogether. These undesirable results, according to GAO, 'can be traced to a lack of disciplined and effective management and inadequate executive-level oversight.'"
