Design for test and the cost of quality

A generalized methodology is presented which can be used to select a cost effective design-for-test technique for use in the design process. The intent is to factor in both increased research and development costs as well as increased production costs. The authors also correlate the expected levels of test coverage. Thus, for a particular design, it is possible to predict the increase in cost of research and development, and increased production costs, and correlate this with test coverage. The tangible factors in the cost of quality can be determined
