In the program capstone:

Learners prepare a full commercial business plan for a compelling new business idea, either for a new business idea or for a new product/service within an existing organization. Learners complete the company analysis, the industry analysis, the customer analysis, the competitive analysis, the marketing plan, the operations plan, the management plan, the full pro-forma financial projections, and an executive summary. Upon completion, Learners present the business plan to a panel of faculty and business executives and are required to orally defend their plan.

The business plan is a perfect capstone, because the plan requires you to bring together all of the aspects of business in one solid document.  

When you've successfully presented your business plan, as well as other courses and electives, you have finished the program.
