I have no idea what your process is, or what checklists exist for you to use.

"make sure these 10 people are all members of these 3 groups...".
doesn't really give much of a clue as to how you would do that.

If you know that "these 10 people all need to be members of these 3 groups...", surely it would be better to ensure your processes take positive action to ensure that is the case.
