Degradation refers to the gradual loss of functionality or performance of a system over time. This concept is crucial in reliability engineering because it highlights the fact that systems do not fail abruptly but often exhibit signs of wear or diminished performance as they age. Recognizing degradation allows engineers to anticipate potential failures and implement maintenance strategies to extend the life of the system.

Unlike a complete shutdown of the system, which signifies an immediate and total failure, degradation is more about the slow and often unnoticed decline in functionality. Additionally, initial rapid failure occurrences relate to the potential for early-life failures but do not describe the ongoing process of degradation. The time taken to repair a system pertains to maintenance and operational readiness, rather than the intrinsic decline in the system’s capabilities over time. Understanding degradation is vital for maintenance planning and improving overall system reliability.
