When a reliability life test is planned it is useful to visualize the expected outcome of the experiment. The Expected Failure Time Plot (introduced by ReliaSoft in Weibull++ 8)provides such visual.

Using the cumulative binomial, for a defined sample size, one can compute a rank (Median Rank if at 50% probability) for each ordered failure.
 
As an example and for a sample size of 6 the 5%, 50% and 95% ranks would be as follows:
 
 
 
{| border="1" cellspacing="1" cellpadding="1" width="400" align="center"
|+ 5%, 50% and 95% Ranks for a sample size of 6.
