Det tredje værktøjSource Control
“At my first job, we had a Source Control department. When you had your code ready to go, you took your floppy disks to the nice ladies in Source Control, they would take your disks, duly update the library, and build the customer-ready product from the officially reposed source.”
- Miles Duke
Det fjerde værktøjContinuous Integration
(and delivery)
Det femte værktøjAutomatiske tests

Time
✓ Timed saved on manual testing ✓ Old bugs do not re-appear ✓ New bugs discovered early ✓ Enables refactoring ✓ Improves design
