Abstract : Operating characteristic (OC) analysis concepts are extended to the reliability growth setting Consumer (Government) and producer (contractor) statistical risks are expressed in terms of the reliability growth curve parameters, test duration, and reliability requirement. For a given confidence level, these risks are shown to depend solely on the expected number of failures during the growth test and the ratio of the MTBF to be achieved at the end of the growth program to the MTBF technical requirement to be demonstrated with confidence. Formulas are developed for computing these risks as a function of the test duration and growth curve planning parameters.
