Requirements volatility
Track how much scope changes after a sprint or release is planned.
Delivery & developer experienceHow it's worked out
- Volatility = (added + changed + removed) ÷ baseline
- Same baseline definition each sprint or release
NoteSome change is healthy in agile work. Sustained volatility above about 20% a sprint usually shows up as missed commitments and rework; track the trend.
