Expert system development is usually a four step process. It starts with the knowledge engineer obtaining an understanding of a particular judgment issue. It is followed by the acquisition of thought processes of experts in solving the issue. Next, a computer model is programmed to reproduce the adopted thought processes of defined situations; if a shell program is unavailable. Lastly, the system is tested and certified to ensure appropriate resulting decisions and usability. These steps are commonly known as: knowledge representation, knowledge acquisition, computational modeling, and model validation.
