Session title 32
A FEW KEY POINTS !• Make process as flexible as necessary without
stress or "muri" (overburden) since this generates "muda" (waste)!
• Long-term philosophy but tactical improvements also valuable !
• Can’t directly attack outcomes without understanding underlying concepts!
• Significant organizational / incentives / culture(?) element !
!!
![Page 33: What manufacturing teaches about DevOps](https://reader034.vdocument.in/reader034/viewer/2022042701/55a6ca8e1a28ab481d8b4870/html5/thumbnails/33.jpg)
Session title 33
CICD PRINCIPLES !
• Maintain a single source repository!
• Automate the build!
• Make your build self-testing !
• Test in a clone of the production environment (usually)!
• Everyone can see what’s happening !
• Automate all the things!
![Page 34: What manufacturing teaches about DevOps](https://reader034.vdocument.in/reader034/viewer/2022042701/55a6ca8e1a28ab481d8b4870/html5/thumbnails/34.jpg)

Session title 35
USING JENKINS FOR CI/CD!
• New build triggered on push to git repository!
• No application downtime during the build process!
• Failed builds do not get deployed (leaving the previous working version in place)!
• Can have different deployment stages (e.g. dev, test, stage, production) !

Session title 37
• Apply agile continuous improvement !
• Ensure that each DevOps process implemented (such as test-driven infrastructure, continuous delivery, etc.) maps to a business impact !
• Monitor for unintended side effects !
• Foster a learning-centric approach to process improvement, rather than to use these exercises as a means to punish missing expectations

• No real concept of inventory with code !
• Capital structures different !
• Cost of failure (may) be different !
• Ability to iterate may be different !
