Define the outcome that must continue
Specify the material, product and delivery requirement you are trying to protect. Then define the disruption under review. A facility with many connections may be important, but graph prominence alone does not establish that its failure stops the buyer's output. Alternative routes, stock, qualification and allocation determine how the failure could propagate.
The DOE supply-chain assessment discusses vulnerabilities across magnet production. For a company-level review, translate that broad context into a precise failure case rather than applying a sector label to every supplier.

Test the substitutes, not just the connections
For each apparently critical operation, identify the documented downstream routes and any proposed substitutes. Ask whether alternatives are qualified, accessible and large enough for the relevant requirement. A second facility on a map may be owned by the same group, share the same feed or produce an unsuitable product.
Distinguish observed structure from assumed impact. An unquantified connection supports a dependency question; it does not specify the volume lost. Record which information would change the finding, such as usable inventory or an independently qualified source.
Illustrative bottleneck review
Three finished-product suppliers rely on one disclosed alloy plant. That plant is a candidate bottleneck. To establish its practical effect, the team still needs to know whether the suppliers hold usable stock or have qualified alternative alloy. The useful conclusion is a prioritised continuity question, not an unsupported claim that all three immediately stop.
From graph finding to decision
| Observation | Next test |
|---|---|
| Shared upstream plant | What alternatives are qualified? |
| No disclosed alternative | Is it absent or simply undisclosed? |
| Potential downstream impact | What quantities and buffers are established? |
Your review checklist
- Define the requirement and disruption.
- Inspect shared feed and conversion stages.
- Test practical substitutability.
- Avoid equating graph centrality with measured loss.

Does a highly connected facility always create the greatest risk?
No. Exposure depends on the product, route, substitution and buffer assumptions, not connection count alone.
Can an undisclosed backup be assumed absent?
No. Treat it as unknown and seek evidence before claiming there is no alternative.
