Which of the following are defined for a given change model?

Detailed Explanation:

In ServiceNow, a change model defines how a change progresses through its lifecycle. The state model refers to the predefined states (e.g., New, Assess, Authorize) a change can transition through. State transitions are the movement between these states. Similarly, a phase model represents the different phases of the change process (such as Request, Authorization, Implementation), which can have distinct requirements and actions. Each of these components defines a clear structure and sequence of events for managing changes effectively.
