Continuous Integration! Raising the Bar

So we implemented Continuous Integration. It gives us the confidence to deliver - great! However, we are in a suboptimal situation and we do not gain all the benefits.

Continuous Integration is one of the most critical practices to adopt to enable the fast flow of work through the value stream. How can we bring our delivery process to the highest standard and reap all the benefits of Continuous Integration?

This session goes deeper into the advanced practices to raise Continuous Integration to a higher level. Learn how to gain fast feedback, increased stability and higher throughput with reduced stress and fatigue!

3. 20 practices that make Continuous Integration
4. Raising the bar
5. Commit Frequently
6. Commit at least once an hour! Preferable, multiple times per hour.
7. Changes are small. It reduces risks!
8. Disables Feature Branches!
9. Gentle design pressure … • work in many more smaller steps • more decoupled code base • speed up the build • hide more unfinished functionality => virtuous circle
10. Decouple the Codebase
11. • Ports & Adapters • Kent Beck’s 4 rules of simple design • Intentional Code Duplication (see Expand-Contract) • Single Responsibility • Dependency Injection
12. Amplify quality Optimise engineering time to introduce change
13. Hide Unfinished Functionality
14. Perfectly acceptable to have unfinished functionality sitting in production
15. Without fancy toggles
16. Sometimes we need Feature Toggles -> we have to manage them!
17. Adopt Expand-Contract
19. Have a Fast Build
20. When the Build is slow • do not execute the Local Build • execute the Local Build less often
21. What is fast? • 10 min is the limit • under 5 min should be the focus • 30s avoids hallway sword fighting 🤷
23. • Commit Frequently • Decouple the Code Base • Hide Unfinished Functionality • Adopt Expand-Contract • Have a Fast Build Raising the bar For faster feedback Thus better quality!
