MTBF and MTTF as the Reciprocal of Failure Rate
MTBF is 1/λ for a repairable item and MTTF is its non-repairable twin; both are summary statistics of a distribution, not a promise about any one unit. The distinction between them, and the arithmetic that connects them to λ, is required before availability, parts-count prediction or any specification can be read.
