Traceability is the capability to identify, record, and follow the history, location, and status of materials, components, and products as they move through each step of a process. In manufacturing and operations environments, traceability links inputs, process parameters, equipment, operators, and outputs so that each unit or batch can be reconstructed and verified at any point in its lifecycle.
Operationally, traceability typically relies on unique identifiers (such as barcodes, RFID tags, or serial numbers), structured data capture at defined process steps, and centralized records in systems like MES or ERP. This allows users to:
- Trace items forward from raw material receipt to finished goods and shipment.
- Trace items backward from a finished product to the materials, equipment, and process conditions used.
- Reconstruct the sequence of events and decisions for a given order, lot, or unit.
Traceability is applied at various levels, including material lot traceability, unit or serial-level traceability, and process traceability (who did what, where, when, and under which conditions). The scope and granularity are defined by internal procedures, regulatory requirements, and industry standards.
