Information Technology: DOD Software Development Approaches and Cybersecurity Practices May Impact Cost and Schedule, Report to Congressional Committees [open pdf - 1MB]
From the Highlights: "For fiscal year 2020, DOD requested approximately $36.1 billion for IT [information technology] investments. Those investments included major IT programs, which are intended to help the department sustain key operations. The 'National Defense Authorization Act for Fiscal Year 2019' included a provision for GAO [Government Accountability Office] to assess selected IT programs annually through March 2023. GAO's objectives for this review were to, among other things, (1) describe the extent to which selected major IT programs have changed their planned costs and schedules since the programs' initial baselines; and (2) describe what selected software development and cybersecurity risks or challenges, if any, may impact major IT programs' acquisition outcomes."
