What indicates that a system element is of their own merit?

The concept of a system element being of its own merit typically refers to its ability to stand alone in terms of its functionality and contribution to the overall system. The assertion that a system element can be decomposed into further subordinate system elements highlights its nature as a building block within a larger system. This characteristic is significant because it ensures that each element contributes value and can be understood and analyzed in its own right, even as part of more complex structures.

Decomposable elements enable clearer definitions of functions, responsibilities, and interfaces in systems engineering, allowing for more effective management, specification, and design of the system as a whole. This hierarchical decomposition is integral to systems engineering methodologies, promoting modularity and clarity, which ultimately aids in analysis, verification, and integration processes.

The other options, while touching on aspects of system elements, do not align as closely with the idea of merit. Self-sufficiency or independence from other elements does not inherently relate to the value or capability of a system element in contributing to the system. Rather, the strength of a system often lies in the interactions between its components. Therefore, decomposability stands out as the most appropriate indicator of a system element's merit.
