• Multiple Integrations per day
• Each integration is verified by an automated build including tests.
• The person who wants to push is responsible to deal with merge conflicts

• Maintain a single source repository
• Automate the Build
• Make your build self-testing
• Everyone commits to the mainline every day
• Every commit should build the mainline on an integration machine
• Fix broken builds immediately
