Any job you take can be traced back to some entrepreneur who started the company or the agency or the shop. A minor in business shows you the world of the enterprise, the organizational creation which brings people together in a new group with a new mission. This minor equips you with technical skills, but even more with an appreciation of what it takes to make an enterprise grow and succeed. You will gain a new sense of how motivating and leading people is the key to good management, and also of the world of risk-taking - scary, absorbing, and ultimately rewarding. All employers value workers who can see the big picture and the context of each individual job, and can find ways to make each part more effective. Your management minor can let them know you're ready to join a team.
Consult with your advisor to determine the best way to coordinate this minor with the requirements of your major curriculum.
