A build traveler is a job-specific document or electronic record that accompanies a product, batch, unit, or work order through manufacturing. It identifies the required operations and captures execution evidence such as completed steps, operator sign-offs, material use, inspection results, quantities, dates, and nonconformance references.
In industrial operations, a build traveler is commonly used to connect the planned production route with what actually happened on the shop floor. It may include work instructions, drawings or document references, tooling requirements, inspection checkpoints, serialization data, and quality hold points. In an MES or digital traveler system, the traveler is often generated from ERP, PLM, routing, and bill of material data, then updated as work is performed.
A build traveler should not be confused with a routing alone. A routing defines the planned sequence of operations; a build traveler applies that plan to a specific job or unit and records execution details. It is also narrower than a complete quality record or device history record, although traveler data may contribute to those records in regulated or traceability-sensitive environments.
