Unit 2: The Design Process
Ask → Imagine → Plan → Create → Improve
Overview
The engineering design process is a flexible, repeatable method for solving problems. Whether you're building something physical or working out a conceptual challenge, these stages help guide your thinking.
In this self-guided lesson, you'll walk through each stage with clear examples. You don’t need a team—just curiosity and a willingness to try, fail, and try again.
The Five Stages of the Design Process
1. Ask: Define the Problem
Start by clearly identifying the challenge you’re facing. Ask yourself:
- What is the problem?
- What constraints or limitations exist?
- What would success look like?
2. Imagine: Generate Ideas
Brainstorm freely. Come up with as many possible solutions as you can—even wild ones. Think creatively and push past the obvious. The goal is variety, not perfection.
3. Plan: Select & Sketch
Pick your most promising idea. Sketch it out. Make a materials list. Think through your steps. Good planning saves time and helps prevent frustration.
4. Create: Build the Prototype
Build a working version of your idea. It doesn’t have to be perfect — it's a prototype. This step turns your imagination into something real.
5. Improve: Test / Revise / Complete
Test your design. What worked? What didn’t? Use your observations to improve it. Add finishing touches. This stage can loop as many times as needed — iteration is key.
