Lots of examples here by Intercom about how to enable teams to ship as fast as possible and at the same time also as safely as possible.

• Be available after shipping
• Ship instrumentation first
• Use feature flags
• Ship to a small subset of traffic
• Ship the “read” path first
• Document and share your plan and actions
