Continuous Integration
- Is everyone committing to the same trunk at least once a day?
- Is every commit being tested?
- When the build breaks Is is red fixed in ten minutes?
Running Jenkins against you feature branch and then ignoring the build when it turns red is not Continuous Integration

- increate dicipline
- increate hygene
- reduce time to market
- decreese feedback loops
- Improve quatly
- Reduce Cost
You should do this if you can, sometime you can't: firemware , mobile apps
