Agile Software Development: DHS Has Made Significant Progress in Implementing Leading Practices, but Needs to Take Additional Actions, Report to Congressional Requesters [open pdf - 2MB]
From the GAO [Government Accountability Office] Highlights: "Many of DHS's major IT [information technology] acquisition programs have taken longer than expected to develop or failed to deliver the desired value. In April 2016, to help improve the department's IT acquisition and management, DHS identified Agile software development as the preferred approach for all of its IT programs and projects. GAO was asked to examine DHS's adoption of Agile software development. The objective of this review was to assess the extent to which DHS has addressed selected leading practices for its transition to the use of Agile software development."
