Final answer:
The testing step of the Engineering Design Process usually involves several rounds of testing, finding new problems, and redesigning and testing again, before finding the final design.
Step-by-step explanation:
True. The testing step of the Engineering Design Process usually involves several rounds of testing, finding new problems, and redesigning and testing again, before finding the final design. This iterative process allows for the identification of weaknesses in the design and provides opportunities for improvement. The testing and refining stage is crucial in ensuring that the final design meets the criteria and constraints set for the project.
