Question: is mttf the same as mtbf?
Answer: Mean Time To Failure (MTTF) is a basic measure of reliability for non-repairable systems. ... Technically, MTBF should be used only in reference to a repairable item, while MTTF should be used for non-repairable items. However, MTBF is commonly used for both repairable and non-repairable items.
