The document discusses continuous delivery, emphasizing practices aimed at building, testing, and releasing software more efficiently. It highlights the importance of deployment pipelines and automation in achieving faster and more reliable software releases, while also addressing challenges like configuration management and stress during manual deployments. Additionally, it provides resources for further reading and tools to facilitate continuous delivery processes.
![Cycle Time
“How long would it take your organization to
deploy a change [to production] that involves
just one single line of code? Do you do this on a
repeatable, reliable basis?”

Editor's Notes
- #8: Cycle Time is a measure of Continuous Delivery maturity
- #9: Collaboration (DEV + Customer, DEV + Operations)Talking early and often…break down walls. [DevOps]Automation. Automate Everything! Build, Test, Deploy!Frequency. Frequent means small. Easier to troubleshoot, rollback. Reduces Risk.Feedback. Change triggers feedback. Feedback is fast. Team acts on it.
- #10: Manual DeploymentsInsufficient Configuration ManagementInfrequent, Error Prone Deployments
