MISSION
A mission is a very big, long-term end-result or achievement. There may be objectives, goals, strategies, executions and tactics all used to achieve the mission, but the mission is the biggest and most important thing to be accomplished.
Mission statements are usually the non-financial achievement that a CEO either develops for his company or is hired to achieve. The mission is a what versus a how, and is very similar to a vision statement in that it has a future orientation.
