operational effectiveness of the Assurance process by assessing the mean time between failures. This metric is measured over a period as the ratio of the Mean time between repairs and the number of trouble tickets closed over the period. The mean time between repairs considers the revenue system size (such as live ports) without taking into account the service outage time (calculated as the MTTR for the period for all the trouble tickets over the period)

Example calculation: Revenue System Size = 15,606 ports * 30 days = 468,180.00 days. MTTR in days = 213.7 mins = 0.148 days. Number of trouble tIckets closed = 4792 trouble tickets. Therefore MTBF = (468,180.00-(.148*4792)) / 4792. Therefore MTBF = 97.6 days. See the Counting Rules tab for more information on how Service Outages are counted to ensure consistency among participants.
