First officer

Starfleet
On ships, the first officer acts out the captain's orders and advises him or her. In Starfleet, this function is usually accompanied by the rank of Commander or Lieutenant Commander. First officers may also be referred to as executive officers.

The first officer is nominally responsible for the smooth running and organization of a ship or starbase, and will often be head of his/her own Executive Department/Division, whose officers and crew - primarily with the Yeoman designation - manage many of the day-to-day administrative tasks for the XO. (The Exec. Dept. would, for instance, provide the captain with a personal assistant).
