The Department of Defense recently completed a study that recommended an information-based approach to implementing an open architecture for integrating diagnostic functions as a critical and enabling step towards achieving the Department's strategic goals of reducing total ownership cost, shortening cycle time for technology insertion and increasing interoperability of fielded systems. There are, however, a number of challenges to successfully implementing an integrated diagnostic process on a weapon systems program to realize these benefits. The underlying source of these challenges is often the less than formal way for test and diagnostics engineers to participate in the systems engineering process and thereby compete for investment resources. To effectively participate in the trade-off studies associated with this process, a clear association must be made between the investment required for a particular integrated diagnostic functionality and the benefits that would be derived. This paper will explore a generic framework for addressing such cost and benefit considerations. To accomplish this, an open, information-based architecture for integrated diagnostics will be defined along with how it would be applied throughout a product life-cycle and the linkage of these capabilities with generic life cycle cost elements. Commercial and government systems will be used to validate these assertions
