Change Failure Rate

Change Failure Rate (CFR) is a metric that measures the percentage of changes or updates to a system—such as software updates—that result in failures or issues requiring additional work, like bug fixes or rollbacks. It indicates how often planned changes cause problems, helping teams assess the quality and stability of their deployment processes. A lower CFR suggests more reliable updates, while a higher rate indicates greater risk. Tracking CFR enables organizations to improve change management practices and reduce disruptions, fostering smoother releases and better overall performance.
