This document discusses how sketching and low-fidelity prototyping can help teams collaborate and drive innovation. It highlights techniques like team sketching, lowest responsible fidelity, cross-functional pairing, and innovation games which use quick, visual, and collaborative methods to create continuous workflow sketches, scenario storyboards, low-fidelity wireframes, and paper prototypes. These techniques helped the Knowsy team develop their first screen designs and launch their app in the App Store, with the platform continuing to evolve through this process.
