A Shorter Truncated Sequential Test

This paper develops a truncated sequential test (TST) for production models that makes use of the preproduction testing and that allows unequal sample sizes from the production and the preproduction models. An example is given that compares the fixed time test (FTT) against the proposed truncated sequential test. In this example a significant reduction in testing required on the production model is achieved. Power tables for such tests are tabulated.
