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.

Most aerospace MRO digital pilots run 3–9 months from kickoff to close‑out, depending on scope, data readiness, approvals, and integration depth. Shorter 6–8 week “sandbox” trials are possible, but anything touching live workscopes, traceability, or integrations usually extends due to validation, customer approvals, and change control.

Digital systems can replace wet-ink signatures for maintenance sign-offs in many regulated environments, but only if the solution, process, and validation evidence meet your specific contractual, regulatory, and customer requirements. You must address identity proofing, controls, audit trails, and change management, and expect mixed coexistence with paper for some time.
