ISO 20000 and ISO 27001 integration

Answer: Being ISO management standards, ISO 20000 and ISO 27001 have many similarities that become easier to integrate them (and this similarities will become clearer after the release of the new version of ISO 20000, that may be in the next two years - currently the revision is half way across the process - https://www.iso.org/standard/70636.html).

Considering the current standard, I advise you to start with the documenting the common procedures and records (e.g., internal audit and management review), considering the requirements of both standards, and after that go for the specificities of each standard.
