There are myriad problems in the world. However, problems are discovered and solved using just 4 basic questions: Why? Who? What? How? These 4 Questions (4Q) are mainly presented using a blank template of the 4Q-Canvas. Nevertheless, some other visual templates such as the 4Q-Iceberg and 6Q-Star are shown. Also, included are variations of the 4Q-Canvas for problem discovery and solving in various domains. This presentation illustrates the power of using the 4Q-Canvas for Universal Problem Solving.
