Failure codes are a way of organizing the most common causes of failure into a list that can be quickly referenced by a technician. Now that we have the MTTA and MTTR, it's time for MTBF for each application. For instance, consider the following table: The table above shows the start and detection times for four incidents, as well as the elapsed time, depicted in minutes. Its an essential metric in incident management MTTR (mean time to recovery or mean time to restore) is the average time it takes to recover from a product or system failure. Because MTTR represents the average time taken to address an issue, it is calculated by adding up all time spend on unscheduled or corrective maintenance in a period, and then dividing this total by the number of incidents in that period. Some of the industrys most commonly tracked metrics are MTBF (mean time before failure), MTTR (mean time to recovery, repair, respond, or resolve), MTTF (mean time to failure), and MTTA (mean time to acknowledge)a series of metrics designed to help tech teams understand how often incidents occur and how quickly the team bounces back from those incidents.
