Learning Targets
- Write test steps connected to the design criteria.
- Plan how user feedback will be collected respectfully and consistently.
- Identify what data or observations will show whether the prototype works.
IED Unit 5 • Lesson 5.11
Testing Protocol and User Feedback Plan
Focus question: How can engineers test whether a prototype solves the user problem?
Your lesson guide
Objective
Write test steps connected to the design criteria. Plan how user feedback will be collected respectfully and consistently. Identify what data or observations will show whether the prototype works.
Materials
For the online work: a browser and your engineering notebook. Follow the activity’s materials list for any physical build, and get teacher approval before using equipment.
Plan your time
Suggested work block: 45–60 minutes. Physical builds and projects may span several classes; follow your teacher’s schedule.
Mission Briefing
Today’s Plan
Use this page with the lesson presentation, your engineering notebook, and the tools or evidence assigned for Design the Test and User Feedback Plan.
Success Looks Like
You can create a testing protocol and user feedback plan connected to criteria and user needs.

Opening Prompt
How can engineers test whether a prototype solves the user problem?
Connect your response to the decision, evidence, or quality standard required for Design the Test and User Feedback Plan.
Reveal: useful engineering move
This lesson is ready to move forward when the evidence meets this standard: Every test or feedback question produces evidence tied to a criterion or user need.
Core Skill
What We Are Practicing
A testing protocol makes evaluation fair, repeatable, and useful.
User feedback should connect to user needs and design criteria.
Good tests measure the claim the team wants to make.
Your Task
Design the Test and User Feedback Plan
Create a fair performance test and a respectful feedback method that directly address the user needs and design criteria.
- Select the criteria and user questions to evaluate.
- Define measures, success thresholds, and trial conditions.
- Write repeatable test steps and prepare the data table.
- Prepare neutral user-feedback questions and consent/privacy expectations as appropriate.
Quality check: Every test or feedback question produces evidence tied to a criterion or user need.
Lesson Interactive
Design a Repeatable User Test
Identify variables, set a measurable success threshold, and choose enough trials to support a conclusion.
| Test element | Variable type |
|---|---|
| Handle diameter used in the prototype | |
| Time required to secure the latch | |
| Glove type and task instructions |
A useful protocol produces comparable data and defines success before testing begins.

Checkpoint: is your evidence ready?
- Check calculations, units, labels, and measurements against the activity requirements.
- Record what actually happened, including unexpected results.
- Explain what you changed and why; attach required drawings, photos, CAD, or code in your classroom assignment.
Submit the evidence specified in the activity and your classroom assignment. The report below collects your notes, calculations, observations, and reflections; attach any required drawings, photos, CAD, or code separately.
A PDF download is not a submission. Review it, then upload it and any required attachments through your classroom assignment system.
