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).
