Meaning
Inventory control practices partition raw materials and finished assemblies into distinct batches to maintain strict quality traceability. Executing lot segregation prevents the accidental mixing of parts from different production runs or component suppliers. This separation ensures that if a defect is discovered, the scope of the issue is confined to a specific, identifiable group of products.
The practice is critical for maintaining clean records in medical and aerospace supply chains.
Traceability Boundary
Each production lot receives a unique barcode identifier that is recorded in the manufacturing execution system. This digital identifier links the finished product to the specific reels of resistors and silicon wafers used during assembly. If a component failure occurs, the boundary allows engineers to identify and isolate only the affected units.
Material Control
Physical partitions and dedicated storage bins prevent different lots from blending on the factory floor. Operators receive clear visual warnings and digital scan prompts before loading parts into the pick-and-place machines. This process prevents the use of unauthorized component substitutions during assembly.
Quarantine Outcome
When a lot fails to meet quality standards, the entire batch is moved to a secure quarantine area for inspection. This action prevents non-conforming products from reaching the packaging station.
