6. Agile Project Lifecycle
Iteration 1 Iteration 2 Iteration 3 …

7. ConJnuous IntegraJon

8. CI inside an IteraJon
Concurrent
Engineering

9. Test-Driven Development
Write a
Failing Test
Code
Write just
enough
Production
Code to
pass the test
Refactor the
Production
Code
Cycle Time:
5-15 min

13. Recap
In agile development, QA is a

TDD, refactoring and CI help built-in
quality
Each iteraJon ends with “potenJally
shippable code”
