Reliability metrics
Reliability metrics are a set of quantitative measures used to evaluate the reliability of a system. Reliability refers to the ability of a system to function without failure over a given period of time. Several reliability metrics are used in the field of engineering, and three of the most commonly used metrics are MTTF, MTBF, and MTTR.
Mean Time to Failure (MTTF)
MTTF is a measure of the average amount of time for which a system or component will operate before it fails. It is calculated by dividing the total operational time of the system or component by the number of failures. For example, if a system has been operating for 10,000 hours and has experienced 5 failures, then the MTTF would be 2,000 hours (10,000/5). This metric is used to assess the reliability of a system and to predict the expected lifespan of a component or system.
Mean Time between Failures (MTBF)
MTBF is a measure of the average amount of time between failures of a system or component...
