Prerequisite(s): ENTR 201. Corequisite(s): ENTR 302. This course takes students who have completed The Entrepreneurial Mindset and Innovation course deeper into the process of startup enterprise development. The course is structured to be delivered in a concentrated format and taken in the same semester as (followed by) Course III, Preparing to Pitch and Launch Your Startup. Teams of students will test their entrepreneurial ideas using a creative "lean canvas" approach to constructing a business model. Students will "get out of the building" and in a cyclical process of trial, feedback and retrial, modify or revise their models, and create prototypes or mockups of their proposed products or services. Each team will be assigned a mentor who is an experienced entrepreneur. The course will culminate in formal presentations by each team to a panel of instructors, mentors and entrepreneurs.
