This document discusses customer segmentation and its benefits. Segmentation involves dividing customers into groups based on characteristics like age, gender, behavior, tastes, and preferences in order to better serve different consumer needs and communicate with customers. An example customer profile is provided of a busy working mom, Gina, who wants high quality, healthy, convenient prepared meals and grocery stores. Segmentation strategies are outlined including perceptual mapping, which positions companies, consumers, and products on graphs to understand how they are perceived.
