Adding reagents slowly over a reaction
@OP, Corribus gave a good answer. Another thing to consider: when a reaction is being held below room temperature, one wants to avoid adding a new reagent (presumably which itself is at room temperature) too quickly, or the reaction will no longer be at the temperature one desires.

It usually comes down to favoring a desired product or influencing reaction rate. E.g.: (1) so that one reactant is always in large excess, which can favor, e.g., monosubstitution vs disubstitution (2) if the reaction is very exothermic...
