Which statement is TRUE regarding enabling systems and their function?

The statement that enabling systems provide critical support without contributing functionality is true because enabling systems are primarily designed to facilitate and enhance the operation of a system of interest (SOI) rather than to deliver direct functional outputs. These systems serve important roles, such as logistical support, maintenance capabilities, or other auxiliary functions that help ensure the SOI can operate effectively. However, the enabling systems themselves may not be directly responsible for the core functionalities that the SOI provides.

Understanding the nature of enabling systems highlights their importance in the broader context of systems engineering. They are instrumental in providing the necessary environment and resources for the SOI to achieve its objectives efficiently, thus making them essential components within the life cycle, even if they do not deliver primary functions themselves.
