In the failure rate model shown below, which one of the sections represents the period when catastrophic failures are likely to occur?
In the failure rate model, which is often represented as a 'bathtub curve,' there are three distinct periods: the early failure period (infant mortality), the normal life period, and the wear-out period. Section A represents the early failure or infant mortality period, where failures decrease over time as defective items are weeded out. Section B represents the normal life period with a relatively constant and low failure rate. Section C represents the wear-out period, where failures increase again due to ageing and wear-out of components. Catastrophic failures are most likely to occur during the wear-out period, which is represented by section C.
