Boundary systems refer to the rules and structures that define the limits of a system, organization, or environment. They help establish what is included or excluded, guiding interactions and behaviors within the system. For example, in a business, boundary systems can dictate roles, responsibilities, and communication protocols among employees. In a broader context, boundary systems can also apply to ecosystems, where they determine the interactions between different species and their habitats. These boundaries can be physical, like rivers or mountains, or conceptual, such as laws and regulations that govern resource use and conservation efforts.
