Observation - performer cardinality

performer - The cardinality is defined as 0…*

Does this mean for a single observation there could be multiple people tagged as performing the observation?

Can you provide a real world use cases where a single observation can have multiple people tagged as performing an observation?

Multiple people involved in doing an assessment (e.g. autism assessment involving several specialists where they create a joint report). Capturing the person and the device responsible for a lab result. Multiple devices involved in performing a test. Capturing the device, the software and the person involved in a test.

Never thought about this scenario before. Thank you for providing such a solid example!
