Start a new facility plan by mapping the current or projected product steps: receiving, inspection, cold space, production or packing, equipment washing, clean storage, and dispatch.

On an architectural drawing, show routes for product, staff, empty or clean containers, used containers, and waste with separate lines. Mark crossings, returns, doors, and thresholds, supporting their frequency with site observations or order and production plans.

Record actual walking or handling distance, waiting time, and loading-door use between receiving, storage, production, and dispatch. Design clean and used separation with the product procedure and authorised quality review.

State area or capacity-growth assumptions using order history and planning scenarios. Verify doors, refrigeration, fire safety, hygiene, and building suitability with relevant engineers, authorities, and facility owners during design.
