Abstract
A method for identifying outlier devices during testing, includes: establishing binning limits for a device being tested based on one or more rules generated from external test results data of tests involving similar devices; receiving test results data in real time for the device being tested while the device is on a device tester; applying the one or more rules to the test results data for the device in real time; determining in real time, based on results of applying the one or more rules to the test results data, whether the device is an outlier with respect to the binning limits; and in response to determining that the device is an outlier, binning the outlier device separately from tested devices having test results data falling within the binning limits.
