Which phase in the Prototyping model involves refining and enhancing the prototype until it becomes the final product

The phase in the Prototyping model that involves refining and enhancing the prototype until it becomes the final product is known as the "Iterative Refinement" phase.

Here are the steps involved in this phase:

1. Review and Revision: After the prototype is built, it is reviewed by the project team and the client. They provide feedback and suggest changes that they want to see in the final product.

2. Refinement: Based on the feedback, the prototype is refined. This involves making changes to the design, adding new features, or improving existing ones.

3. Testing: The refined prototype is then tested to ensure that it meets the project requirements and works as expected. Any issues or bugs that are found during testing are fixed.

4. Iteration: Steps 1-3 are repeated as many times as necessary until the prototype meets all the project requirements and the client is satisfied with the product. This iterative process is what gives the Prototyping model its name.

5. Finalization: Once the prototype has been refined and tested to the point where it meets all the project requirements and the client is satisfied, it becomes the final product. This is the end of the Iterative Refinement phase and the Prototyping model.
