One of the pivotal elements of supply chain management is the identification and traceability of products and services. Product traceability empowers manufacturers to monitor the entire lifecycle of a product, from raw material sourcing and production processes to packaging and distribution. This applies to all product types, including final assemblies, sub-assemblies, component parts, raw materials, and services.
Relevance of ISO 9001 Standards
Product identification and traceability have been central to ISO 9001 standards, from its inception to its most recent version, ISO 9001:2015. Clause 8.5.2 of ISO 9001:2015 outlines three fundamental requirements for identification and traceability:
- Identification of Outputs: Use appropriate mechanisms to ensure conformity of products and services.
- Status Identification: Continuously monitor and measure outputs during production and service delivery.
- Traceability Control: Maintain documented records for uniquely identifying outputs when traceability is required.
These mandates necessitate manufacturers and service providers to maintain robust evidence of product and service identification and traceability through documented records. Documentation may include barcodes, ERP records, route cards, job cards, work orders, inspection tags, process sheets, project logs, or status reports.
The Evolution of Traceability in Manufacturing
Historically, traceability was predominantly manual and adopted for critical products to meet customer requirements. For instance, in the early 1990s, a manufacturing company producing current collection units for railways resolved a trial failure incident by backtracking through inspection and machining records. Using serial numbers and documented inspection logs, the root cause—a machining error due to operator oversight—was identified and rectified. This illustrates how traceability mitigates production bottlenecks, enhances throughput, and reduces waste.
Benefits of Product Traceability
- Operational Efficiency: By tracking raw material movement, manufacturers can manage inventory more effectively and avoid production delays.
- Regulatory Compliance: Traceability is mandatory in industries like food, pharmaceuticals, and automotive to ensure adherence to safety, quality, and environmental standards.
- Improved Accountability: Multiple stakeholders, including design engineers, operators, quality inspectors, suppliers, and logistics providers, are responsible for maintaining traceability through accurate documentation.
Methods for Product Identification and Traceability
Procedures for product identification and traceability vary across industries but generally include:
- Products: Assigning unique part numbers, revisions, or serial numbers for components and assemblies. This can be achieved via physical marking, batch numbers, or storage tags.
- Raw Materials: Tracking materials with batch or lot numbers upon receipt, often linked to purchase orders or supplier documentation.
- Tooling: Assigning unique tool identification numbers validated against engineering data to differentiate them from product or raw material identifiers.
- Services: Identifying deliverables with titles, document numbers, revision numbers, and release dates to ensure traceability to specific contracts or projects.
Role of ERP in Traceability
Modern Enterprise Resource Planning (ERP) systems have revolutionized traceability by integrating it into core functionalities:
- Codification: Unique item codes help identify product attributes and differentiate items.
- Lot/Batch/Serial Tracking: ERP systems allow seamless tracking of items, enabling traceability from procurement to production and final delivery.
- Complaint Resolution: ERP features facilitate root cause analysis for customer complaints by linking production and supply chain records.
- Integration with Advanced Technologies: Barcoding, RFID tagging, and blockchain integration with ERP systems ensure real-time, automated traceability.
