Step-by-step explanation:
Members of an organization who are not necessarily guided by their organization's goals, but share a common interest in the survival of the system are considered members of a normative organization. Normative organizations are voluntary organizations that are based on shared interests. People join them voluntarily and find membership rewarding in an intangible way, receiving non-material benefits. Examples of normative organizations include the Audubon Society and a ski club.
