I don't think it's hard to infer from the context and example.

An organic team is a group of individuals that forms spontaneously within an organization based on informal communication networks and interpersonal relationships rather than formal directives or predefined structures. Such teams typically emerge in response to a specific need or opportunity and are composed of members from various departments who collaborate based on shared goals and complementary skills. Unlike traditional teams, their existence is not documented in official organizational charts, and their composition can be fluid.
