Limitation of expert system Knowledge in not always readily available
It is hard, even for a highly skilled expert to abstractgood situational assessment when he is under timepressure.
The vocabulary that experts use for expressing factsand relations is frequently limited.
The approach of each expert to situational assessmentwhen he is under time pressure.
Most expert have no independent means of checkingwhether their conclusions are reasonable.
