The engineering design process

This lesson focuses on the engineering design process. Interdisciplinary approaches reveal connections that single-subject study might miss.

The engineering design process is a systematic, iterative approach to solving problems. Steps: (1) Define the problem—what need does your solution address? What are the constraints (cost, size, materials) and criteria (what success looks like)? (2) Research—what do you know? What have others tried? (3) Brainstorm—generate many possible solutions without judgment. (4) Select and plan—evaluate ideas using decision matrices (rate against criteria); choose the most promising. (5) Build prototype—create a test version using available materials. (6) Test and evaluate—does it meet the criteria? Where does it fail? (7) Improve—redesign based on what you learned; repeat steps 5–7. "Fail fast" is a design principle: small, cheap failures early prevent large, expensive failures later. Real engineering combines technical knowledge, creativity, teamwork, and ethical consideration of impacts on society and environment.

As you engage with this material, consider both the theoretical foundations and practical applications. Think critically about how this concept builds on prior knowledge and where you might apply it beyond the classroom.

Challenge yourself to go beyond memorization—seek to understand the "why" behind the processes and principles.
