What must a function consist of according to the RCM Standard?

The correct choice highlights the essential components of a function as defined by the Reliability-Centered Maintenance (RCM) Standard. A function is fundamentally a statement that describes what an asset is supposed to do. This includes a verb, which indicates the action taken, an object, which represents the thing upon which the action is performed, and a performance standard, which establishes the expected level of performance for that action.

In this context, the verb specifies the action that the asset needs to perform, such as "drive," "pump," or "heat." The object is the result of that action, for example, "the vehicle," "the fluid," or "the space." Lastly, the performance standard sets a benchmark for success, defining how well the asset should perform its function under various conditions.

Understanding these components is crucial for creating effective maintenance strategies that ensure assets operate reliably and meet organizational goals. This comprehension aligns with the objectives of RCM, which focuses on maintaining system functionality while considering reliability, safety, and maintenance costs.
