My rule of thumb is the following:
1. If you can flow-chart on a piece of paper the logic that you are trying
to implement, then you should be able to implement your rules using
if/then/else procedural logic else, you will be better off using a rule
engine.
2. Another reason why you may want to use Jess (a rule engine) is if the
logic that you are implementing will change frequently. Using a rule engine,
you will get a good separation between your application and the logic. With
a rule engine, you will be able to change the logic of your application
without needing to alter the application itself.
3. Another reason for using a rule engine is taking advantage of inferencing
(forward and/or backward chaining) and conflict resolution. Although a lot
of rule base applications that I have seen do not really need inferencing,
it is there if you need it.
