Explanation
The elicitation technique that the BA should select to enable the customer and the key stakeholders to visualize the final product is prototyping. Prototyping is a technique that involves creating a simplified or partial version of the solution that can demonstrate its features, functions, and appearance. Prototyping can help to elicit, validate, and verify the requirements, as well as to obtain feedback and approval from the stakeholders.
Prototyping can also help to reduce the risks, costs, and time of the project by identifying and resolving any issues or gaps before the final implementation of the solution. References:
