The Yorktown Expert System/MVS Manager (known as YES/MVS) is an experimental expert system that assists with the operation of a large computer complex. The first version of YES/MVS (called YES/MVS I) was used regularly in the computing center of IBM's Thomas J. Watson Research Center for most of a year. Based on the experience gained in developing and using YES/MVS I, a second version (YES/MVS II) is being developed for further experimentation. This paper discusses characteristics of the domain of large computing system operation that have been illuminated by the YES/MVS I experience, and it describes the modifications in the design of YES/MVS II that are an outgrowth of the YES/MVS I experience.
