Making It Work for Someone Else

Lab Brief #7

🎯 Your mission

Set it up. Test it. Be amazed.

⚡ The twist

Every solution creates a new problem. That's good — that's the next project.

What you'll learn

A design is only good if the person who has to use it can. Testing your build with a real user almost always finds something you never noticed, because you already knew how it was supposed to work.

Key words

user
The person a design is built for.
feedback
What a user tells you after trying your design.

Make a hypothesis first

Predict: which design will hold the most weight?

Say your guess out loud — then find out if you were right.

Get ready

🧰 What you need

card
tape
scissors
notebook

⚠️ Safety first

Use scissors carefully and cut away from your fingers.

Step 1 of 4 · Read

Think about what you just learned: say what "user" and "feedback" mean in your own words before you start.

Step 2 of 4 · Do

Design a pencil holder for a specific person in your class. Let them use it for one day, collect three pieces of feedback, and make one change based on the feedback rather than your own preference.

Step 3 of 4 · Observe

Record what actually happened, including anything that did not match what you expected.

Step 4 of 4 · Record

Write a conclusion that answers the question this lesson opened with, and state your uncertainty.

Question 1 of 2

Testing with a real user usually reveals:

How sure are you?😐 maybe

Question 2 of 2

Feedback should be collected from the:

How sure are you?😐 maybe

Mind = blown
