Overall Stage Goal
At this point in APQP, design features are almost final, but still open to refinement based on Voice of Customer (VOC), operational feasibility, and cold chain compliance needs.
Even if the product design comes from the customer or brand owner, the cold chain supplier/distributor must still review it critically to ensure it can:
Survive the chilled/frozen supply chain without damage or spoilage. Meet HACCP/ISO 22000 requirements for safety and quality. Be manufactured, packed, stored, and transported at scale within temp control limits.
Key Planning Steps in Cold Chain
Build sample runs of the product and packaging to confirm it matches what the customer actually values — e.g., texture, flavor, shelf life.
A frozen bakery prototype might be tested for crust crispness after 6 months at –18°C and reheating.
Cold chain twist: Also test “temperature abuse” resilience — e.g., what happens if the frozen meat spends 30 minutes at –10°C during loading?
For chilled mascarpone: Filling equipment must keep product under 8°C during packing, even at peak throughput.
For frozen fish: Carton design must allow fast freezing to ≤ –18°C core within 4 hours. Factors to confirm: Production volume capability. Timing vs. shelf-life window. Unit cost and packaging material availability.
Based on engineering drawings and specs, anticipate where in manufacturing cold chain risks could occur.
Eg: Identify a sealing machine as a potential failure point if it overheats packaging film and weakens the seal.
Preliminary Feasibility Analysis Early risk review for potential manufacturing + cold chain problems: Will handling frozen cartons at –20°C cause material cracking? Will chilled beverage caps shrink during blast chilling, causing leaks?
