Annex A Controls

Answer: ISO standard's content is defined by technical committees that can be different for each standard. For example, for ISO 27001 the technical committee is the ISO/IEC joint technical committee JTC 1, while for ISO 22301 the technical committee is the ISO/TC 292 Security and resilience. These committees work with different contexts and point of views that may result in situations like this one you mentioned, where the ISO 27001 committee decided this standard should have a set of controls attached while the ISO 22301 committee did not see reason for such details to be attached (in fact, guidance for ISO 22301 is available on ISO 22313 - https://www.iso.org/standard/50050.html).
