Abstract
This chapter provides guidance for the development, documentation, testing and distribution of expert systems. The guidance is directed at expert systems developed for wide distribution, as well as systems developed for use by a single or a very small number of users. It is the intent to describe a process that anticipates the problems that could be encountered and allows flexibility in the development of expert systems. Topics covered are: a structured approach to identify the candidate problem for an expert system development, knowledge engineering, knowledge representation, the development team, system design and development, system testing and evaluation, and distribution and maintenance of expert systems.
