02 / Complete-line interfaces
Design normal production and the conditions that disturb it
Crowded shelves, uncontrolled temperature, fading labels, broken packs or absent disposal rules can make retention samples unreliable during an investigation. Map raw materials, packaging, product, people, tools, chemicals, waste, air, water, power, heat and information from site entry to dispatch. Review doors, airlocks, level changes, drainage, cleaning access, maintenance removal routes, forklift paths and every boundary between production and support rooms. Review startup, steady production, short stops, restart, low or high demand, format or recipe change, cleaning and shutdown. The interface must protect both the incoming condition and the requirement of the next module.
