What is the role of a System Boundary?

The role of a System Boundary is to delineate what belongs to the system and what does not. This is critical in systems engineering as it helps establish clear distinctions between the system under consideration and its external environment. By defining the boundaries, engineers can focus on the components, interactions, and relationships within the system while also understanding how it interfaces with outside elements.

Establishing the System Boundary aids in identifying requirements, constraints, and interactions with external systems or components. It ensures that stakeholders have a mutual understanding of what is included in the system's scope and what lies outside of it. This clarity is essential for effective communication, reduced risks of scope creep, and ensuring that the system is designed and evaluated correctly against its intended operational use.

While identifying operational goals, enhancing performance, and defining user interfaces are important aspects of systems engineering, they do not specifically capture the essence of delineating the system from its environment, which is the core function of the System Boundary.
