Critical nodes (Flow)
Where a company's identified chain narrows, on Flow's Exposure tab, with what documents state kept apart from where the node sits.
"In the company's chain" lists the parties and goods a reader should know by name. Each row has two columns that are never combined. Documented: a stated single source, a limited number of sources, a replacement time a company states, a Critical tier from stated figures, a Severe or High bottleneck and the companies it is stated critical for, a supplier the company shares with its customers or competitors. Position: how many parties sit up and down of it, and how far downstream an interruption there was walked to reach. "Across the network" is the Keystones ranking.
How to read it
A parent and its named subsidiary count once. A row's documented facts each open the sentence behind them.
Limitations
Position is arithmetic over the identified network, not a claim about the business.
Also called: critical nodes, in the chain, across the network, shared supplier, position, documented.
