In the context of reliability, failure is often characterized as a complete loss of functionality, meaning that the system is unable to perform its intended function. This definition aligns with the understanding that when an object or system fails, it has ceased to operate entirely, rendering it nonfunctional for its intended purpose.

Partial functionality or intermittent function does not align with the strict definition of failure; systems may still deliver some level of performance in those states. Minor issues or problems can suggest that a system is still operable, albeit not at optimal efficiency. Therefore, the emphasis on "no function at all" highlights that true failure signifies a total breakdown rather than a reduction in capacity or performance. This clarity is crucial in fields such as production and operations management, where reliability directly impacts overall operational efficiency and effectiveness.
