Supply chain stress test

Choose what breaks: a part, or one company. See who else supplies the part, how concentrated it is, which customers disclose a dependence on the suppliers, and which real machines name it. It reads the whole catalog in your browser; nothing is estimated.

Questions

What does this tool do?
Pick a part, or a company, and it lists who else makes the part, how many of them are publicly listed, which ones carry a sourced placement, which customers disclose a dependence on them, which machines name them, and how much news touched the part in 90 days. Everything is computed in your browser from the same catalog data as the rest of the site.
How is "concentration" decided?
By counting listed companies placed on the part: one is a sole listed supplier, two or three is narrow, four or more is broad. It uses the catalog only, so a part with few catalogued suppliers can look narrower than the real market. Inferred placements count as suppliers but are marked, because they are leads rather than disclosures.
Is this a forecast?
No. It shows structure, not probability. It says who is exposed if a supplier or a part is disrupted, not whether that will happen or what it would do to a share price.
