A statistically exact procedure for producing lower bounds on the reliability of a parallel system of independent, exponentially failing components has been produced by Lieberman and Ross. This method uses individual component failure data to estimate system characteristics. The method has the drawback that permuting the order in which components fail but not the inter- failure times, can alter the estimated bound, i.e., the estimates are Data Order Dependent. In this paper we investigate this dependence of the estimates, and consider the effects of a prior ordering.
