This document provides instructions for using a feedback capture grid to systematically collect feedback on presentations and prototypes. The grid has four quadrants labeled with symbols - a plus sign for things people like, a delta sign for constructive criticism, a question mark for questions raised, and a light bulb for new ideas. Users are instructed to place feedback in the appropriate quadrant, such as putting constructive criticism in the upper right quadrant. This helps ensure feedback is captured in different areas to provide a balanced perspective.
