Failure codes are a way of organizing the most common causes of failure into a list that can be quickly referenced by a technician. Possible issues within processes that may be indicated by a higher than average MTTR can include: But a high MTTR for a specific asset may reflect an underlying issue within the system itself, possibly due to age, meaning that the amount of time it takes to repair the equipment is increasing or unusually high.
