The difference between the two is knowing that the mission is the objective for the organization, while goals are little steps you take toward achievement. For it to become a mission, you set forth toward something more significant. The purpose of the organization has been created to demonstrate caring about something passionately.
It could be human and societal needs, as well as problems within a community, and it means to have a vision of the bigger picture. Goals are accomplished in smaller increments to attain the bigger goal of the organization, which is the mission.
Goals should be specific, quantifiable, attainable, reasonable, and time-efficient. Goals and missions could be outside of the business arena as well. For example, the overall mission is to lose weight over time, but the goal is for you to eat healthily and exercise that day.
