"Segmenting, at its most basic, is the separation of a group of customers with different needs into subgroups of customers with similar needs and preferences."

M.B.'s insight:

Big Data and technology have changed how companies approach segmenting. “The old model, particularly in the market research world was, ‘I understand people’s needs and attitudes, and behaviors will come from that,’”

Forsyth explains. “Today, in many situations, [marketers] have flipped it to say, ‘I’m going to do segmentation based on their behaviors, and then I’m going to try to understand the needs that drive behavioral differences.”
