Which is the correct sequence of the six steps of the Engineering Design Process commonly taught in 8th grade?

• A. Define the problem; generate possible solutions; plan and design; build a prototype; test and evaluate; iterate to improve.
• B. Define the problem; plan and design; generate possible solutions; build a prototype; test and evaluate; iterate to improve
• C. Define the problem; generate possible solutions; plan and design; test and evaluate; build a prototype; iterate to improve
• D. Define the problem; generate possible solutions; plan and design; build a prototype; iterate to improve; test and evaluate

Answer: (A)

The sequence starts by clarifying the problem and the goals, then generates multiple possible solutions, then plans and designs a chosen approach, builds a prototype, tests and evaluates how it performs, and finally uses what’s learned to iterate and improve. This mirrors how engineers think: begin with what needs to be solved, explore several ideas, settle on a feasible plan, create a tangible model, assess how well it works, and use that feedback to refine the design. The other orders misplace steps—for example, planning before brainstorming can limit ideas, testing before a prototype isn’t feasible, and iterating before testing skips essential evidence to guide improvements.
