Implementing Supply Chain Traceability Across the Manufacturing Lifecycle

Traceability in manufacturing spans the entire product lifecycle, starting with raw material sourcing and supplier management. At this stage, manufacturers track materials from their origin to the factory, monitor supplier quality, and record batch numbers and specifications. This information forms the foundation for traceability efforts throughout production. Systems to enable traceability of products through identification, movement, and transformation are essential for maintaining high standards of food safety and supply chain management. Food traceability is particularly important in supply chain management and logistics for ensuring safety and quality control, as well as meeting regulatory requirements and enhancing customer confidence.

In production and assembly, each step of the manufacturing process is documented. Components are tracked as they move through assembly, with records kept of equipment used and operator information. Internal traceability helps in monitoring the movement of parts within a specific area in the supply chain, such as a single company or plant. This detailed tracking continues into quality control and testing, where all checks, test results, and inspections are logged. Any defects can be linked to specific batches or production runs, enabling swift identification and resolution of issues.

Packaging and distribution mark the next phase of traceability. Finished products receive unique identifiers, and their movement through warehouses and shipping channels is recorded.
