Meaning
Physical or digital routing documents accompany work-in-progress units through every stage of assembly to record completed operations and operator sign-offs. Maintaining traveler logs provides a step-by-step history of component fabrication, inspection results, and tool usages. The documentation protocol governs routing verification, operator sign-offs, and quality clearance gates.
Scope ends once a product completes final inspection and its operational history converts into a permanent archived lot file.
Document Flow
Operators initial routing sheets upon finishing specific assembly tasks. Barcode scans update central tracking databases as parts move between work centers. Workstations require documented completion signs before releasing parts downstream.
Process Omission
Skipping manual sign-offs or losing physical routing sheets creates unverified production steps that halt assembly progression. When operators fail to update records during shift handovers, downstream workers cannot verify whether mandatory heat treatments or inspection steps occurred. Pilot builds managed by dedicated engineers often feature pristine documentation, but high-volume line speeds induce record-keeping omissions when manual data entry burdens technicians.
Uncertified processing steps require costly non-destructive testing or complete part scrapping.
Verification Record
Quality assurance staff review physical routing entries and electronic stamp logs before releasing finished assemblies for distribution. Audit teams verify that every required inspection gate contains authorized signatures and matching calibration stamps. Discrepancy checks cross-reference recorded timestamps against machine log files to detect manual logging errors.
Traveler logs establish process compliance across multi-stage manufacturing workflows.
