leadership, a well-informed program office, and a cohesive and committed government and contractor team, Agile could enable the DoD to deliver IT capabilities faster and more effectively than traditional growing number of programs continue to chart new paths in this field. This guide is intended to support that growth, as well as to capture the best practices and lessons learned by these early Agile adopters execution will take time, trial and error, and shaping of processes, policies, and culture, but with support from oversight and process owners can reach the full potential of Agile development. Agile Acquisition

CREATION OF DEV, TEST, AND PRODUCTION ENVRIONMENTS i. Major contributing cause of issues stems from releases representing the first time we see how an application behaves in a production-like environment ii documentation, procedures, etc. 7. Application configuration files 8. This also includes pre-production and build processes 9. Tools iv. 2014 State of DevOps Report – use of version control by Ops Routinely kill and replace production instances v. Keep developers’ environments most current e. MODIFY OUR DEFINITION OF DEVELOPMENT “DONE” TO INCLUDE RUNNNING IN PRODUCTION-LIKE ENVIRONMENTS i. In

equipment for monitoring 1. Create telemetry in application & environments (to include production, pre-production, and CD pipeline) iii. Ian Malpass, Etsy – “If Engineering at Etsy has a religion, it’s the systems being monitored.” c. CREATE APPLICATION LOGGING TELEMETRY THAT HELPS PRODUCTION i. Dev & Ops create production telemetry as part of their daily workii. If it was important enough for an engineer engineer to implement, it is certainly important enough to generate enough production telemetry so that we can confirm that is it operating as designed and outcomes are being achieved. iii. Logging Levels

that has functional capabilities (how it is used today) but also latent capabilities (how it will support future agility and how it will offer options in the future). Build Versus Buy: In a world where passes its tests; that is a yes-or-no question independent of quality.  Once the feature is in production, we can assess its quality based on its fit to need, or perhaps its actual success in accomplishing simply an efficient process we use to select among alternatives. Shadow IT Agile ways of working support a community approach to IT, where IT leaders achieve their objectives by mobilizing the skills and
