- 1. Software Development A Crash Course for Non-Developers | | Webmaster @ www.hierkommtmartin.deHermann Vocke @hamvocke
- 2. Who of you is NOT a Developer? Don't worry, that's not a bad thing
- 3. I bet all of you still have heard some of the terms... Agile Development TDD Continuous Delivery Continuous Integration Waterfall User Stories ...at least once
- 4. But do you really know what all of these mean? No problem, we'll figure this out together.
- 5. Disclaimer This Brownbag is very limited in time and will force me to rush through stuff. In this Brownbag I will be oversimplifying stuff that is actually more complex. I will be opinionated. I will only scratch the surface of many topics. Some stuff I tell might be utterly wrong. Feel free to yell at me at the end of the Brownbag.

- 20. #003 Multiply an arbitrary amount of numbers "As a user I want to be able to multiply an arbitrary amount of numbers so that I can see the result of the multiplication."
- 21. The benefits of TDD Better code quality Fewer bugs A safety net for changing software
- 22. Continuous Integration Merge the team's code changes as often as possible
- 23. Practices of Continuous Integration Build the software automatically Test the build automatically
- 24. Continuous Delivery Continuous Integration on Steroids
- 25. Practices of Continuous Delivery Everything that Continuous Integration does, plus: Test the software automatically in multiple stages Deploy the software automatically
- 26. Why is CI/CD a good thing? You test your application with every commit "Good" versions will be deployed automatically Fast feedback for the team Features go from development to production insanely fast
