Framework overlap

Does ISO 20400:2017 cover ISO 19011:2018?

You hold ISO 20400:2017 and have been told to do ISO 19011:2018. Here is how much overlaps, control by control.

31% of ISO 19011:2018 you already have

ISO 20400:2017 already covers about 31% of ISO 19011:2018, leaving 33 of 48 controls as genuinely new work.

Already covered 0 Likely covered 15 New work 33

No control in ISO 20400:2017 maps directly to one in ISO 19011:2018. Everything counted as covered is covered because both map to the same third standard, which is what a crosswalk is, but it is an inference rather than a lookup.

What is genuinely new work

Nothing in ISO 20400:2017 reaches these. This is the list to scope.

How this is calculated

Already covered means a mapping runs from a control in ISO 20400:2017 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.
