The problem
One small change can affect many SKUs.
The real challenge is the relationship between SKU, material, supplier, facility, certificate evidence, expiry, and change events.
If those relationships are not explicit, a supplier change or expiring document becomes a manual investigation.
The portfolio state should answer: what is affected?
When a supplier or material changes, the impact path should immediately point to the SKUs and evidence that need attention.
Disconnected data
SKU, material, supplier, and evidence live as separate lists.
Expiry surprises
Renewal only becomes urgent when time is already short.
Impact is unclear
One change can affect many SKUs without being obvious.
