Overview of Rule Resolution in PEGA PRPC

Overview of Rule Resolution


Pegasystems’ patented Rules technology is the foundation of Process Commander BPM solutions, providing flexibility and agility. Rule resolution is the process used to identify which rules are applied to a specific business decision. At execution, Process Commander dynamically selects the right process or business rule depending on the business purpose, product, organization, RuleSet and version, date, time, customer-associated circumstance, and security for each rule required. Through dynamic rule selection, Process Commander provides flexibility that is otherwise impossible (except with the alternative of applying rules specified in code).

PEGA Concepts: Class Inheritance and Rule Resolution

The Use class-based inheritance to arrive at the correct rule to execute checkbox defines how inheritance (through the class hierarchy) affects this rule. For this functionality, there are two main types of rules:

• those that can be defined as attributes or aspects of other classes
• those that are not aspects of other classes, but stand alone


There are some types of rules, like Activities, Models, Whens, Decision Tables, etc., which may be “applied to” or “defined on” other classes.
