A risk-based expertsystem development methodology has been developed at NASA Goddard Space Flight Center to provide guidance to project managers and technical personnel and to serve as a standard for developing expertsystems. Concerns expressed by managers of expertsystem development projects are discussed. A description is given of the expertsystem life cycle and the risk-based expertsystem development methodology. Features of this methodology that address specific managerial concerns are reviewed.< >

Based on the development of PRXDM, an expertsystem for the fault diagnosis of the PRX/A electronic telephone exchange, a development life-cycle for expertsystem development is proposed. Seven phases are identified: domain definition, general design, detailed design, prototype development, integration, field testing, and operation. Provision is made for the extensive iteration and incrementation that is an essential part of all expertsystem development. A framework for testing. verifying, and validating expertsystems is presented, and relevant metrics that could be collected in each phase of development are suggested.< >

expertsystems (ESs) have associated risks that managers need to know as they consider new projects. The research reported is aimed at establishing a quantitative approach to assisting managers in identifying these risks. Results of empirical studies and new automated tools are discussed. The risks included: developing an application that fails to represent the expert's knowledge; failure to produce a usable system; upsetting people and groups within the organization who may feel threatened by the planned ES application; and exposing themselves or the organization to legal liability claims resulting from a malfunction of an ES application.< >
