Final answer:
The most appropriate step for the engineering team to do next is to evaluate the feasibility of each idea.
Step-by-step explanation:
The most appropriate step for the engineering team to do next is to evaluate the feasibility of each idea. After generating and exploring several different ideas, it is important to assess each concept to determine if it can meet the requirements and constraints of the design problem. Evaluating the feasibility will help the team identify the ideas that have potential and can be further developed.
