Building business rules: task roadmap

A business rule is an ideal solution when you want to have flexibility to change your business process at run time.

The rule group is the primary element of a business rule, it provides the interface between the business process and the rule logic. The rule group also defines date ranges during which specific rule logic applies.

Some business rules are better suited to a decision table, some to a rule set.

The rule logic is either a rule set or a decision table.

By creating a template for your rule set or decision table you can build up a library of rule logics that you can reuse in the future. The template also allows you to stipulate which parameters of the rule logic can be modified by the business analyst using the Business Rule Manager. Additionally constraints can be applied to these parameters so that the changes made with the Business Rule Manager are within acceptable ranges.
