Because the metric is used to track reliability, MTBF does not factor in expected down time during scheduled maintenance. MTTR can be mathematically defined in terms of maintenance or the downtime duration: In other words, MTTR describes both the reliability and availability of a system: The shorter the MTTR, the higher the reliability and availability of the system.
