Application overlays and the business change management process
An application overlay is an application that is built on top of a decision management enterprise application. An application overlay defines the scope in which business users can change the application (for example, by managing propositions, modifying business rules, or running simulations) to adjust the application to constantly changing business conditions and requirements.
System architects define the application overlay components, such as the revision ruleset or revision records, during the implementation process of Pega Customer Decision Hub.
