A product-history app could connect an individual serial number to assembly, inspection and service records. The business needs to decide which events must be recorded and who is authorised to confirm them.
Scanning a code could open the correct record, with permissions separating production staff, service partners and customers. Corrections should preserve history rather than erase an original inspection entry. Offline collection may be useful where connectivity is limited, with clear synchronisation status.
Start with one product range and follow sample units through their real lifecycle. Test a replaced component and an incorrectly scanned label. The app can support traceability, but a complete-looking timeline should not be described as proof that every physical event was accurately recorded or every product requirement satisfied.
