I just volunteer. Dispatch and endorsement program are definitely separate job. Ideally there will be an office/department for each.
That said, if we were to have dedicated offices for these, we may as well as bringing back permanent ministries (with detailed minimum responsbilities defined in laws). A minister may head more than one ministry as PM decides and the PM is free to set up more ministries/offices as needed.
The permanent ministry setup can be as granular as this: Foreign Affairs, Defence, Culture, Roleplay, Information (dispatches, forum posts, public media,…) , Engagement (active recruitment), Card, World Assembly. I do think the Assembly ought to decide the responsibilities of the executive branch more granularly as IRL governments do. The PM has freedom on assgining personnel to run these. One person may run many ministries at once if desired. To this day, I still haven’t seen the benefits of every single cabinet term drawing up new ministry structure from scratch. There should be some sort of bare minimum setup with discretionary additions and personnel assignment.
