Feature flags at program scale
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
use flags across teams without leaving a mess.
Planned topics
- Flags decouple deploy from release and give instant rollback of behavior.
- At program scale: name flags consistently, record an owner and purpose, and list them in one registry.
- Each migration flag has an expiry or removal date and a ticket.
- Avoid flag interactions: document which flags depend on which, and test key combinations.
- Remove flags promptly after cut-over; leftover flags become hidden code paths.
