Separation of Concern
Think of any dungeon* you've seen - or have written - with a map of the layout, lists of encounters for each room, key items and notes on where they are hidden. How many times have you, as GM, had to skip, rearrange, shuffle or rebuild parts in response to the party's actions? Exactly.
Separating the elements means more flexibility. Generally, the dungeon map doesn't care what monsters lie within and the monsters don't care what important treasures they guard. So if we plan loosely we can make it easier to change or add things on the fly.
