Final answer:
Set-based design supports design flexibility by considering multiple design options in parallel, which allows for adaptable solutions to changing requirements.
Step-by-step explanation:
The concept that helps with design flexibility to support changing requirements is set-based design. This approach to design allows for a broad exploration of potential solutions by considering multiple options simultaneously and narrowing the choices as more information becomes available. It provides a framework that supports design flexibility and validation from multiple directions, leading to a more optimized and adaptive solution.
In set-based design, alternatives and their implications are explored in parallel to converge on a final design. This method contrasts with point-based design, which involves selecting a single design option early and then proceeding to refine that option without considering others. Set-based design promotes greater flexibility by maintaining multiple design options for as long as possible, thus enhancing the ability to adapt to changing requirements or constraints.
