objective = goal

objectively = in an unbiased manner (without the influence of personal feelings or preferences)

Definitions:

(1) (objective as in: our objective is to...)
a goal (some end desired to be achieved)
(2) (objective as in: an objective viewpoint)
fact-based without the influence of personal feelings or preferences

Objective is often contrasted with subjective--which means "influenced by personal belief, feelings, or preferences (rather than being based purely upon fact)."
(3) (meaning too rare to warrant focus)
Less common meanings of objective include:
- In philosophy -- existing outside of the mind.
- In grammar -- the object of a verb or of certain prepositions.
- In optics -- the lens nearest the object being viewed
