The lack of a systematic approach to the management of expertise represents a major difficulty forknowledge engineers.In this paper,we present a framework for assessing knowledge-based expert sys-tems.We show by examples.how this framework may be used to guide the development of thesesystems.Finally,we discuss the implications of this-work and suggest areas of interest for future research.
