This paper describes Bayesian method for degradation test planning with Wiener process. We use conjugate prior distributions and criteria based on estimating a unilateral confidence interval of reliability metric. One criterion is based on a precision for a credibility interval for failure probability. We provide simple closed form expressions for the relationship between the needed numbers of paths and measures (total number of degradation increments) and the precision criteria. An example is used to illustrate the method.
