WebFailure rates at the beginning of the early failure stage are high, but then they decrease with time as the early failures are removed. 2. Useful life: This is the center stage of the bathtub curve and is characterized by a constant failure rate. This stage is the most significant stage for reliability prediction and evaluation activities. WebEarly life failure rate (or infant mortality): This phase is characterized by a relatively higher initial failure rate, which decreases rapidly. Normal life: This phase consists of a relatively constant failure rate, which remains …
