This document discusses identifying market problems. It defines market problems as existing inefficiencies, awkward workflows or non-optimal solutions for a target market. The document explains the difference between stated needs that customers explicitly identify versus silent needs that are problems without defined solutions. It provides examples of evaluating market problems based on their urgency, pervasiveness, and whether customers will pay to have the problem solved. Finally, it outlines performance tasks for students to identify problem products and describe the issues they have in a scrapbook.
