Change Failure Rate

Change Failure Rate is a metric that measures the number of changes made to a system that result in a failure or an incident, such as an outage or a service interruption. It is used to measure the stability of the system and to identify areas where the change management process could be improved.
The formula for Change Failure Rate is:

Change Failure Rate = (Number of Failed Changes / Total Number of Changes) * 100%

It is calculated by measuring the number of changes made to a system that result in a failure or an incident, and dividing that by the total number of changes made to the system. The result is then multiplied by 100% to express the result as a percentage.

For example, if a system undergoes 100 changes and 4 of them resulted in a failure or an incident, the Change Failure Rate would be 4%.

It’s important to track the Change Failure Rate over time, compare it against industry benchmarks, and track it by different segments, such as by different teams, products, or customers, in order to identify where the problem is and take action to reduce the Change Failure Rate.

Change Failure Rate is an important metric for companies that have a large number of changes to their systems, it allows them to identify trends in the stability of their systems and to make informed decisions about the change management process and resource allocation.

It’s also important to keep in mind that the Change Failure Rate should be aligned with the business requirements and the needs of the end-users, a high Change Failure Rate can cause instability and service interruptions, and a low Change Failure Rate can mean that the system is not adapting to the changing business needs.
