Business Continuity is more than ISO 22301/22313
The ISO 22300 family of standards for Societal Security is much more than the well known ISO 22301 and the not so well known ISO 22313.
So, at the time this document was prepared, there were 14 standards directly related to Business Continuity, listed in the document, and others related to image systems, by example.
How many standards in the list provided in the linked document do you know, have heard or used in your BCMS?
