Describe how a business analyst uses prototyping techniques to elicit and validate requirements.

Prototyping is a powerful technique used by business analysts to elicit and validate requirements, especially when dealing with complex systems, user interfaces, or unclear stakeholder needs. A prototype is an early sample, model, or release of a product built to test a concept or process. Prototyping allows stakeholders to interact with a tangible representation of the solution, providing valuable feedback and insights that may not surface through traditional requirements gathering methods. The business analyst leverages prototyping to refine and validate these requirements, ensuring that the final product meets the stakeholders' needs and expectations. Here's how a business analyst uses prototyping to elicit and validate requirements: 1. Elicitation of Requirements: Visualizing the Unseen: Prototyping helps stakeholders visualize the proposed solution, particularly when they have difficulty articulating their needs or when the requirements are abstract. Example: Imagine a project to develop a new online banking application. Stakeholders may struggle to describe exactly how the transaction history page should look and function. The business analyst can create a low-fidelity prototype (e.g., using wireframes or mockups) to show different layouts and features. By interacting with the prototype, stakeholders can provide specific feedback, such as "I want to see the transaction date, amount, and description in a clear, tabular format" or "I want to be able to filter transactions by date range and category." Uncovering Hidden Requirements: As stakeholders interact with the prototype, they may discover new requirements that they hadn't initially considered. This is because the prototype makes the solution more concrete and allows them to think through the user experience in more detail. Example: While reviewing a prototype of an e-commerce website, a stakeholder might realize that they need a feature to allow customers to save their shipping address for future purchases. This requirement might not have been identified during initial requirements gathering sessions but becomes apparent when the stakeholder visualizes the checkout process in the prototype. Facilitating Communication: Prototyping provides a c....
