+## Intent
+The Business Delegate pattern adds an abstraction layer between
+presentation and business tiers. By using the pattern we gain loose coupling
+between the tiers and encapsulate knowledge about how to locate, connect to,
+and interact with the business objects that make up the application.

+## Applicability
+Use the Business Delegate pattern when
+
+* you want loose coupling between presentation and business tiers
+* you want to orchestrate calls to multiple business services
+* you want to encapsulate service lookups and service calls
