ANALYST is deployed in 230 GMAC domestic branch offices. There, each year, 400 credit analysts perform nearly financial analyses of automobile dealerships. Using ANALYST they will save an estimated 55,000 man-hours. The focus of this knowledge-based system, from the very beg, was its end user -- a credit analyst. Driven by singular end user requirements, developers extended the native AI tool explanation facilities, built an easy to use interface and completed the integration of engineering workstations in GMAC’s IBM computing environment.
