Final answer:
Rough prototyping after the design process is finished allows for testing and refining the design, but it can also involve significant changes and be time-consuming.
Step-by-step explanation:
Rough prototyping after the design process is finished can have advantages and challenges. One advantage is that it allows for testing and evaluating the design in a real-world context, which can reveal weaknesses and areas for improvement. It also provides an opportunity to refine the design to better meet the criteria and constraints. However, a challenge of conducting rough prototyping after the design process is the potential for significant changes or modifications to be required, which can be time-consuming and costly.
