When prototyping is used as a requirements validation technique, an executable model of the system is demonstrated to end-users and customers so they can:

Experiment with the model to see if it meets their real needs and identify missing or incorrect requirements

Replace the need for a requirements document entirely

Produce the final test documentation for the system

Write source code for the final system directly from the prototype

Correct Answer

Experiment with the model to see if it meets their real needs and identify missing or incorrect requirements

Explanation

In prototyping-based validation, an executable model of the system is demonstrated to end-users and customers. They can experiment with the prototype to see if it meets their real needs — helping to identify missing requirements, incorrect requirements, and misunderstandings before the actual system is built.
