The failure rate typically decreases slightly over early life, then stabilizes until wear-out which shows an increasing failure rate. This should occur beyond useful life.

Webfailure rate. Discussions on failure rate change in time often classify the failure rate into three types of early, random and wear-out failure regions (the so-called “bathtub” curve). However, there is no clear definition for determining the boundary between these regions. Figure 1: Time-Dependent Changes in Semiconductor Device Failure Rate WebA beta equal to 1 models a constant failure rate, as in the normal life period. And a beta greater than 1 models an increasing failure rate, as during wear-out. There are several ways to view this distribution, including probability plots, survival plots and failure rate versus time plots. The bathtub curve is a failure rate vs. time plot.

An important aspect of the Weibull distribution is how the values of the shape parameter, β, and the scale parameter, η, affect such distribution characteristics as the shape of the pdf curve, the reliability and the failure rate.
