You recently agreed to serve as a judge for a business plan competition at the college or university you attend. A week before the presentation, you received an e-mail from the organizer of the competition with some last-minute information. One comment in the e-mail struck you. The organizer of the competition said, "I think you'll be really impressed with the research the students have done to validate the markets for their ideas." If this statement is accurate, what type of research would you expect to hear from the student teams that you listen to?
