Quality time-What's so bad about rule-based programming?

The frustration expressed by some leading researchers in the field with the limited number of large systems deployed based on expert-systems technology is addressed. It is argued that the problem is related to the inherent nature of rule-based programming. It is maintained that systems developed with the rule-based paradigm are unmaintainable, untestable, and unreliable. It is concluded that unless knowledge engineering has a set of mechanisms to address reliability and maintainability, it is headed for a crisis.<
