This document discusses market segmentation and targeting. It begins by outlining the learning outcomes, which are to understand how segmentation is used to create value by dividing large markets, how to decide which segmentation bases to use, and how companies select target segments. It then provides definitions of markets and segmentation. The key points are that segmentation involves dividing a heterogeneous market into homogeneous subgroups, and that effective segmentation requires identifying distinct consumer groups, selecting target segments, and developing unique value propositions for each. The document also discusses approaches to segmentation like mass marketing, product differentiation, and target marketing, as well as common bases for segmentation like geography, demographics, and psychographics.
