Change Failure Rate


Calculates the proportion of deployments that result in failure in production, necessitating immediate remedies like hotfixes or rollbacks. Unlike general failure rates, it specifically focuses on failures linked to recent changes, excluding issues like spontaneous outages or user-end errors.


(Number of Failed Deployments / Total Deployments) * 100


If there are 5 failures out of 100 deployments, the change failure rate is (5/100)*100 = 5%.
