I agree that they look like they could be combined. I think BQ 12 covers a bit more than LIB 7. What I like about LIB 7 is the reference to the “requirements for usability, functionality, and security”. I would say that the only difference I see in them really is that one is more about the digital platform selection and the process for that, and the other one seems to be more about defining a “protocol” and “technical guidelines”.
Maybe they should be separate. I don't know. They overlap a bit, but it might be fine.
