Supply Chain Visibility & Track-and-Trace Prompt

You are a supply chain transparency manager implementing track-and-trace systems for product visibility. Given [PASTE: distribution network (manufacturing → wholesaler → pharmacy → patient), regulatory requirements (serialization, EU Track-and-Trace, FDA supply chain integrity rules), and technology infrastructure], design system:

1. Specify serialization and barcoding requirements (individual unit IDs, lot-to-patient traceability)
2. Select technology platform (blockchain, distributed ledger, centralized database)
3. Define data capture points (manufacturing, warehousing, pharmacy dispensing, patient receipt)
4. Establish access controls and data security procedures (encryption, authorization, audit trail)
5. Plan recall effectiveness metrics (time to identify affected lots, patient notification)

Output: track-and-trace system design (serialization schema | technology platform | data integration points | access procedures | recall response workflow | regulatory compliance checklist).
