Ownership
Motivation

- Curious and Learn
Customer Obssession

- focus on how it contributes to end customer/business/value
Measure Productivity
Few tenets:
- Optimize as close as dev phase
- Pay attention to on-board phase
- Speak Same Language (same code style via checkstyle, same standard via SpotBug, same coverage via dryrun)
Metrics to watch:
- commit messages like a story
- commit pattern
- RedFlag: revert commits (revert revert is a hard stop)
- CR comments
- Pipeline stats
- PreProd success rates
- Prod rollbacks
- Priority Deployments
- why do you need patch?
- why can’t do patch as deployment?
- least required testing coverage ASAP
