In functional statements, what must protective functions define?

Protective functions in functional statements are designed to specify the conditions under which these functions activate in order to safeguard assets and maintain their operational integrity. Defining protective functions with logic that includes phrases like "if" or "in the event of" allows stakeholders to clearly articulate the scenario that triggers a protective action. This logical structure outlines the necessary conditions for responding to potential failures or hazardous situations, thereby enhancing safety and reliability.

In contrast, options such as cost savings, performance metrics, or specific maintenance schedules focus on different aspects of asset management or performance evaluation rather than the conditions that necessitate protective functions. Therefore, while those elements are important in their own right, they do not address the specific requirement of defining the conditions under which protective functions will operate.
