4. eXtreme.NET Quick Definitions What is XP? What is.NET ? What is eXtreme.NET ?

5. eXtreme.NET Thinking Out of Focus? Technology –Features –Toys Process –Methodologies –Best Practices People

6. eXtreme.NET What is software? CODE!

7. eXtreme.NET CODE Code is what it is all about software product = some code

8. eXtreme.NET Better Product = better code –Easy to install –Has functions the user wants –High quality repeatedly works –Upgradeable more features the user wants easily added

9. eXtreme.NET It's not hard! So why do software projects fail? –We should use language ‘xyz’ –We should use technology ‘abc’ –We should use these complex patterns That we don’t actually need –We should use these practices That are not suitable for this project

10. eXtreme.NET We make it more complex than is needed Makes us look smart Justifies our high salary Covers our arses –'It was a tough project, no wonder it failed!'

11. eXtreme.NET STOP IT NOW! Do the simplest thing that could possibly work.

12. eXtreme.NET How? Let me show you....

13. eXtreme.NET Iteration 0 The automated build file The installer

14. eXtreme.NET Demo Simple build batch file

15. eXtreme.NET Planning game Customer meeting User stories Task break down

16. eXtreme.NET The Development Cycle Test Code Test Refactor Test Integrate

17. eXtreme.NET Test Driven Development Test First Programming Test Frameworks support TDD NUnit

18. eXtreme.NET The Why Questions Why do we need tests in our code at all? Isn’t that the job of the testers? Why do we have to write test code? Why not do manual testing? Why write the test code before the ‘proper’ code? Why doesn’t this whole process cost the customer more?

19. eXtreme.NET Refactoring Changing the structure of code while maintaining the behaviour

20. eXtreme.NET The Why Questions Why not just get it right the first time? Why not just start again if you know it’s wrong? Why can’t I just refactor at the end of the project? Why does this help me develop more robust code? Why should I do it when no one else does? Why do something that doesn’t add any new features to the code?

21. eXtreme.NET Demo TDD and refactor

22. eXtreme.NET Testing the GUI It’s SO HARD –Yes so is writing good software! It’s actually not so hard –use reflection

23. eXtreme.NET Spiking the unknown When you find an area you don’t fully understand –Explore –Experiment –Explain

24. eXtreme.NET Ship It! Anytime you have a green screen Should be ready to ship your software everyday
