i Approved for Public Release; Distribution Unlimited. 14-0391ii Executive Summary The Department of Defense (DoD) needs an acquisition framework for information technology (IT) that all of the DoD’s IT acquisition challenges, but offers a set of principles that can help reduce cycle times and risks to deliver IT in a complex environment. “The US joint force will be smaller and never know less than on the day you begin your new project. Each incremental delivery / review cycle adds knowledge and provides insights that the team could have never known when initial requirements

Digital Delivery… *The internet is widely agreed to have been ‘publicly released’ in 1993 with release of the World Wide Web (WWW) into the public domain, which allowed users to create websites; however World Wide Web in 1989, per CERN. Source: Google, USA Department of Defense, CERN Internet – Public Release 1993* Knowledge Distribution Evolution = Over ~Six Centuries25 …Knowledge Distribution – 2022+ Digital + Generative Delivery *We define the public launch of ChatGPT in November 2022 as the public release of Generative AI which we see as AI’s ‘iPhone Moment.’ ChatGPT saw the fastest user ramp ever for

for verifying transactional isolation, based on cycle de- tection.1 The monotonic test finds dependency cycles over increment-only registers, the txn-cycle test finds write-read dependency cycles over read-write realtime guarantees, but our results hold both with and without those constraints. 1The details of our cycle detection strategy are somewhat involved, and will be published in an upcoming paper. 3 3 Results cally speed up convergence. TiDB has a patch adding an initialized flag to the upcoming 3.0.0-rc.3 release; deployment systems could use this flag to ensure full region replication as a part of cluster setup

Deployment & Release are distinct with different purposes ii. Deployment – installing a specified version to a given environmentiii. Release – when a feature is made available to customers. 1. Release of functionality actions, release becomes a business decisions, not a technical decision v. Environment-based Release Pattern – multiple environments available, only one is receiving live traffic. Release performed Application-based Release Pattern – modify application to selectively release functionality by small configuration changes. Feature flags, dark launching h.
