Complex lists of features with associated data to allow a lot of  control.

Feature Rule Sets

• Associated to the user
• Comprised of Feature Items

Feature ITEMS

• Can be "ON", "OFF" or "NOT-SET"
• Have a timestamp for when last changed
• After authentication the user's features are compared to rules

Feature Rules

• Have a timestamp
• Have a condition
• At request time the timestamp and on/off/not-set flag are compared to the rule and the actual feature is here turned on or off for the user
• Allows purely random samples, or more complicated rules, for example email regex or an is employee check

Managing / Using Flags

• If it is for a feature that all users will have default to on, create a feature flag to disable.
• They use feature flags to hide a branch of component trees
• They use feature flags to develop component branches  - ComponentA and children for feature flag a, ComponentB and children for feature flag b
• They avoid feature flag use on the server, preferring to simply set up new endpoints when necessary
