Continuous Delivery seeks to deliver increased Business Agility by releasing smaller releases more frequently. For a development team, this may mean shorter sprints or a switch to Kanban. But what about the PMO, testing teams, and release management? To truly leverage Continuous Delivery, enterprises must consider impacts that span functional silos.

- 22. IBM Corporation ©2013 Two big bottlenecks • Manual regression tests are too slow • Never allocated enough time Testing • Manual / semi-scripted deployments are slow • Errors in deployment are risky and waste QA time Deployment

- 24. IBM Corporation ©2013 Deployments should be automated Differences in dev and ops environments and procedures cause failures Time to market pressure for more frequent releases Manual (tribal) processes for release lack repeatability/speed Major releases take days, 100 people and are organized by spreadsheet Daily Build Release Who did this last time? Dave… Dave’s not here man… Dev Prod I’ll order breakfast
- 25. IBM Corporation ©2013 Deployment: Two approaches Build Pipeline Tool - Perform a build, promote build through environments CI tool + Application Deployment Automation Tool - Applications are made up of several builds

Test n Prod Functional Tests Performance Tests Monitoring These are 1 tool in a pipeline model These are 2-3 tools in CI + ADA model
- 27. IBM Corporation ©2013 When is each approach appropriate? Pipeline Simple apps Low coupling between components / services Tests validate ONE version of ONE thing Shared tool ownership ok Build + ADA More complex applications Higher coupling between components / services Tests validate that the larger system is working Dev wants to own build, Ops wants to own deploy
- 28. IBM Corporation ©2013 Most people fall into the Build + ADA pattern Pipeline here

Editor's Notes
- Hey! Hotfixes/patches are like that and all organizations do those!How long does it take to do a hotfix? What gets in the way? What are the risks?How would you feel about doing one 10 times a day?Continuous Delivery is treating all work as a hotfix.
- Cycle time is not just how long it takes to develop a set of requirements and get it to “gold master” status. It is the entire process from “I think we may want to do X” to “X is now in production and usable by real customers.”That includes the funding process, requirements gathering, and getting it from “code complete” to production. It is very, very, very hard to shrink just development (aka “construction”) without shrinking all of the rest. They are surprisingly interdependent.
- This has always been considered to be “the most efficient” and to “reduce the most risk”
