Aerospace manufacturers manage part genealogy using a combination of serialized IDs, controlled BOMs, routings, and digital records across MES, ERP, PLM, and supplier systems. Effective traceability depends on data discipline, integration quality, process maturity, and consistent use of identifiers across plants and tiers in the supply chain.

Digital work instructions can replace paper travelers under ISO 9001, but only if you can demonstrate equivalent or better control of documents and records, traceability, and data integrity. Acceptance depends on system design, validation, change control, auditability, and how electronic travelers coexist with existing ERP/MES and QMS processes.
