Abstract

In this paper we discuss the benefits of a Test Program Set (TPS) that can precisely isolate down to the absolute lowest component of a UUT (Unit Under Test) versus a TPS´s ability to accurately detect AND isolate a fault to some higher level of the UUT. We touch on the idea of not isolating down to this absolute level just because we can, but only when we need to as an optimum characteristic of the support system. As in all things, the competing ideals of theory, need and desire slam up against the boundaries of reality. Essentially, we try to view the environmental realities that a system must deploy in. The cost of complete, precise diagnostics and fault isolation is high. In this paper we discuss various trade-offs that developers and decision makers make to design, develop and deliver a TPS that supports the user in the most optimal and cost effective way
