Feature Flag Rollout Risk Planner

Calculate rollout risk, blast radius, and canary release safety. Enter values for instant results with step-by-step formulas.

Worked Examples

Example 1: Database Migration

Problem:High complexity (8), High severity (10), Low mitigation (3).

Solution:Rollout 10%. Risk is High.

Result:Recommendation: Reduce rollout to 1% (Canary) or improve testing.

Frequently Asked Questions

How long should a rollout take?

It depends on traffic. You need enough statistical significance to prove safety. High traffic sites might rollout in hours; low traffic might take days.

Does complexity increase risk linearly?

Often exponentially. Complex code interacts with other systems in unpredictable ways (emergent failure).
