In "The Back of the Napkin," Dan Roam introduces a revolutionary approach to problem-solving and idea generation that leverages the power of simple drawings and visual thinking. With the premise that anyone—even those most averse to drawing—can use visual tools to clarify complex ideas, Roam demystifies the process of visual thinking. Through engaging anecdotes and accessible strategies, he guides readers on how to use sketches and diagrams to communicate ideas more effectively, innovate, and solve problems creatively. Drawing on two decades of experience in visual problem solving, combined with insights from vision science, Roam's book is a testament to the untapped potential of thinking in pictures. Roam's method is both a revelation and a return to the most basic form of expression: the simple act of drawing on a napkin. By breaking down visual thinking into a few simple tools, "The Back of the Napkin" empowers readers to harness their innate visual skills to see problems in new ways and to convey their solutions with clarity and impact. Whether you're looking to streamline a business process, communicate a new concept, or just see the world from a fresh perspective, Roam's book is a compelling guide to thinking outside the proverbial box. With "The Back of the Napkin," you'll never look at a napkin—or a problem—the same way again.
