Yes, MRO turnaround KPIs can be mapped to ISO 22400 concepts, but it is an alignment exercise, not a one-to-one standard mapping. You will need to translate asset- and event-centric MRO metrics (TAT, AOG risk, induction/teardown/repair cycles) into ISO 22400 objects and time categories, validate data definitions across systems, and accept that some measures remain MRO-specific extensions.
