WebThe so-called bath-tub curve represents the pattern of failure for many products – especially complex products such as cars and washing machines. The vertical axis in the figure is the failure rate at each point in time. Higher values here indicate higher probabilities of failure. The bath-tub curve is divided into three regions: infant ... WebThe 'bathtub' refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathrub curve has 3 regions: The first region has a decreasing failure rate due to early failures. The middle region is a constant failure rate due to random failures. The last region is an increasing failure rate due to wear-out failures.
