Gen Y consumers are a unique breed. But what exactly makes them different from their elders? Our research unearthed nine attributes of Gen Yers' social, emotional, and mental makeup that shape their perception of interactions. To reach these young consumers, we've identified four design approaches: immediacy, Gen Y literacy, individualism, and social interactivity. To truly engage Gen Y, firms should create a Gen Y advisory board and apply Gen Y design approaches across touchpoints.
