Teaching

Description: Entrepreneurship is a way of looking at things that is opportunity-focused and creative. The goal should be about creating value for customers and investors, gaining independence in your career, taking bold risks, and solving challenges with novel solutions. To be an entrepreneur, you need to develop the ability to innovate—to improve the old and invent the new. You need passion—doing what you love. Above all, you need persistence: getting up every day and moving forward with no one telling you what to do or why to do it. The course will cover core concepts involved in identifying project ideas, composing business plans, and formulating teams to pursue a project. The students will be selecting their projects from current grand challenges and ideas with entrepreneurship potential from a wide range of commercial and government sources. During class, we will be performing an assessment of the business and market fit of new ideas. The course will engage the students in project team building and leadership. As part of the project pitch, the students will learn how to perform discovery and substantiation of the initial target customer.

The course material will be posted and administered in VT Canvas.
