Which resource provides a testbed that demonstrates a complete workflow involving multiple resources?

• A. StructureDefinition
• B. GraphDefinition
• C. ExampleScenario
• D. OperationDefinition

Answer: (C)

The main idea here is identifying a resource that models an end-to-end workflow using multiple FHIR resources. ExampleScenario is designed to illustrate a complete business process by laying out a sequence of steps, actors, and activities that involve several resource types working together. It serves as a testbed by providing a realistic, runnable scenario that shows how data flows and how resources interact across the entire workflow, such as creating a patient, linking encounters, procedures, observations, and other related resources to achieve a concrete outcome. This makes it ideal for testing interoperability and workflow logic in a realistic context.

StructureDefinition defines constraints on a single resource type, not a whole workflow. GraphDefinition describes how resources are related in a graph for exploration, but it isn’t a ready-made end-to-end scenario. OperationDefinition specifies a specific operation on resources, not a full multi-resource workflow.
