Critical physical node
A site, supplier, utility, process or asset that has an outsized effect on the operating model.
A critical operating node is the point that the business cannot easily absorb or replace.
If it fails, the rest of the operating chain usually slows down with it. That is why a mitigation priority should be tied to the node, not just the headline event.
