Abstract
Expert systems are excellent tools for application to problems of diagnosis. However, creating an acceptable diagnostic system is not only a task of collecting, analysing and coding knowledge. The sequence in which questions are asked of a user consulting the system and the speed with which it "homes in" on a correct diagnosis are just as important as having a large and verified knowledge base. Several different strategies for controlling these factors are presented in this paper using examples of actual systems. The facilities provided in typical expert system shells are shown to be not particularly convenient for implementing such strategies but examples of coding are given.
