What happens if a study task is assigned to an arm, but otherwise has no rules?

If you create a study task and assign it to a study arm, but do not create any rules – the task (and any others in a similar situation in that arm) will activate immediately upon an individual being assigned to that arm.

The order the tasks will be presented to the participant is the order in which they were created in the study flow.

Except for the first task presented to a participant after arm assignment, you’re going to want to create an activation rule. This will give you more control over when a task is presented to a participant and create a better participant experience.
