Prototyping is a tool or technique that could have been used by the business analyst to avoid the situation of unclear and conflicting requirements. Prototyping is the process of creating a simplified and partial version of the product or system that can be used to elicit, validate, and refine the requirements. Prototyping can help the business analyst and the stakeholders to visualize the solution, to identify and resolve any issues or gaps, and to reach a common understanding and agreement on the requirements.
