Product/material identity
Item numbers, versions, units and status must be consistent or intentionally mapped across PLM, ERP, MES and quality systems.
Routing / process definition
Operations, sequence, resource eligibility and work instructions need clear lifecycle ownership and effective dates.
Resource hierarchy
Plants, areas, lines, cells and equipment should have stable identifiers that support both execution and analytics.
Change control
Engineering changes need coordinated effective dates across master data, MES instructions, quality checks and machine recipes where applicable.
Digital thread
The digital thread is less about one database and more about preserving identity and relationships as information moves across lifecycle systems.
MES terminology and boundaries vary among plants and vendors. Validate data ownership, safety impacts, interfaces and change control against your actual manufacturing architecture and approved procedures.
