EVR (Escape Velocity Rate) shows whether defects are entering your backlog faster than your team can resolve them.
When EVR exceeds the event horizon, instability accelerates and recovery becomes costly.
Traditional QA reacts after defects pile up.
3S uses EVR to proactively rebalance resources.
Explore the Impact Hub
Estimate your current EVR, understand the cost of operating in a critical state, and see the ROI of using STAR to stay ahead.
