The document describes a method for creating representative personas to understand a target audience using a "Skewered Box Model". The model involves defining the three most dominant parameters to segment the audience, setting a scale for each, and then plotting representative personas across the scales. This helps ensure the personas fully represent the audience's diversity. The personas are then given additional attributes to bring them to life. The skewered box model provides a systematic way to capture an audience in a three-dimensional space to inform product planning and design.
