The AMSAA_BISE reliability growth model for multiple systems development derived by the second approach is incorrect as well. The practical failure data, it included 35 systems’ reliability growth test data and 80 systems’ field data, cannot show its correctness of AMSAA_BISE model, it shows that there is something wrong with AMSAA_BISE model.
