What is catastrophic failure?

Catastrophic failure generally refers to a sudden, often unexpected breakdown or failure of a system or service, which can be explored across technical and broader societal contexts. In engineering disciplines, reliability engineering deals with managing the lifetime risks and uncertainties of system operations to prevent unexpected failures. Meanwhile, definitions of failure itself depend on context, observer perspective, and whether clear criteria exist.

What we know

• Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure and deals with predicting, preventing, and managing lifetime risks and uncertainties of failure. [1, 2]
• Reliability is defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time or in a defined environment without failure. [2]
• Failure is a social concept representing the non-fulfillment of a desirable or intended objective, with criteria that depend heavily on context and observer perspective. [3]
