Abstract
This study develops a technique for predicting purchasing quality costs and studying their behavior as random variables. The resulting model extends prior research that treats purchasing costs deterministically or not at all, thereby providing a valuable decision and planning tool for companies that are placing an increasing reliance on purchased components. The model was tested in the field at a small defense contractor. Test results suggest that purchasing costs can be reduced by using the model to select the lowest cost policy from a set of three alternatives.
