How this is calculated
Already covered means a mapping runs from a control in IEC 62443 to that control. Likely
covered means no direct mapping exists but both frameworks map to the same control in a third
standard. New work means neither. We keep those separate rather than adding them into one
friendlier number, because blending them would present a two-hop inference as a verified
fact.
Coverage is not symmetric.
Run it the other way and you will get a
different number; both are correct.
From 332,959 cross-framework control
mappings across 723 frameworks, 531 of them verified against
their source documents. It does not tell you that you are compliant: a mapped control means
the two standards ask for the same thing, not that you have done it.
