9. Best Practice: Validated Merge
• Shield your repository
• Rely on Jenkins…
– Push your code to Jenkins
– Jenkins builds, verifies and merges with
upstream
• Result
– No downtime due to bad commits
– Tremendous productivity boost

10. Best Practice: Templates
• Talk in the users domain specific
language
– Shield them
• Capture sameness of jobs, build steps
– Replicate them
• Faster route to success
– building plugins without writing code
