What distinguishes a Story change from an Actor change?

The distinction between a Story change and an Actor change lies in how they interact with the policy management system. A Story change typically involves modifications that necessitate additional steps, such as provisioning. This means that when a Story change is made, there is an expectation for certain resources or configurations to be allocated or set up to reflect the change properly within the policy.

On the other hand, an Actor change directly triggers automatic policy calculations. This means that the system can immediately reassess and adjust itself based on the new parameters or conditions introduced by an Actor change without the need for manual intervention or provisioning. This automatic response is crucial for maintaining real-time security controls and adapting to dynamic environments.

By understanding this difference, it becomes clear why the answer highlighting the role of provisioning in Story changes and the automatic nature of Actor changes is the accurate one.
