What role do start points play in a smart walk thru?

Start points are crucial in a smart walkthrough as they designate the exact moment when the walkthrough begins for the user. By providing a clear initiation point, start points help users understand when they are entering guided assistance, ensuring a structured and coherent experience. This is essential because it sets the context for what users can expect as they navigate through the walkthrough. Without a defined starting point, the guidance might be confusing or misaligned with user expectations.

The other options focus on aspects such as feedback, permissions, and data reporting, which, while important in the broader context of user experience and engagement, do not directly describe the primary purpose of start points within a smart walkthrough. Start points specifically relate to engagement initiation, making them integral to the overall effectiveness of the guided experience.
