capabilities faster and responding more effectively to changes in operations, technology, and budgets. This guide provides DoD acquisition professionals with details on how to adopt Agile practices within each element apply. Agile requires a set of processes, roles, and culture that will take time to employ. This guide is intended to show how the DoD could tailor the Defense Acquisition Framework to benefit from Agile but don’t know how to apply Agile within the unique and complex DoD acquisition environment. This guide seeks to adapt proven principles of Agile development specifically to the DoD context. More and
