Standard : Feature toggles allow decoupling of deploy and release timelines
Purpose and Strategic Importance
This standard ensures that feature toggles (flags) are used effectively to separate the deployment of code from the actual release of features to users. This decoupling provides greater flexibility in release timing, supports incremental rollouts, and reduces deployment risks.
It supports the policy “Enable Just-in-Time Production” by enabling teams to deploy frequently while controlling when features become active. Without this standard, deployments and releases are tightly coupled, limiting agility and increasing risk.
Strategic Impact
- Enables safe, controlled feature rollouts and quick rollback if needed
- Supports experimentation, A/B testing, and gradual feature exposure
- Reduces risk associated with large or complex releases
- Increases deployment frequency and velocity without compromising stability
- Improves alignment between technical delivery and business readiness
Risks of Not Having This Standard
- Inflexible release schedules tied to deployments
- Increased risk of user impact from premature feature exposure
- Reduced ability to test features in production safely
- Higher rollback frequency and release failures
- Lower customer satisfaction due to unstable releases
