Add internal transfers to the product-flow map; do not treat an unmeasured corridor or staging area as risk-free by default.

Scan the batch or handling-unit code at freezer exit, store receipt, picking, palletizing and dispatch handoff. Record timestamp, location and team at each point; report total and stage-level dwell.

Choose a validated device and measurement point representative of product conditions under the quality plan. If a vehicle/container is used, consider its instructions, loading pattern and product requirements together.

Compare records with product specification and approved process limits. On deviation, identify and segregate the lot pending quality disposition; adjust staging, pick order or dispatch appointments using evidence.
