There are some really good tips on delivery and best practice, in summary:
Speed comes from making the safe thing easy, not from being brave about doing dangerous things.
Fast teams have:
- Feature flags so they can turn things off instantly
- Monitoring that actually tells them when something’s wrong
- Rollback procedures they’ve practiced
- Small changes that are easy to understand when they break
Slow teams are stuck because every deploy feels risky. And it is risky, because they don’t have the safety nets.
