Why prototyping validates design ideas in Figma - Business Case Study

Scenario Mode

👤 Your Role: You are a UX designer working with a product team

📋 Request: Your manager wants you to show how prototyping helps validate design ideas before full development

📊 Data: You have user feedback data from initial sketches and interactive prototypes created in Figma

🎯 Deliverable: Create a report with visuals that explain how prototyping catches design issues early and improves user satisfaction

Sample Data

Prototype Version	Number of Users Tested	Issues Found	User Satisfaction Score (1-10)
Sketch	10	15	5
Low-Fidelity Prototype	15	10	6
High-Fidelity Prototype	20	3	8
Final Design	25	1	9

1

Step 1: Create a table visualization showing Prototype Version vs Issues Found

Use bar chart with X-axis = Prototype Version, Y-axis = Issues Found

Expected Result

Bar chart showing decreasing issues from Sketch (15) to Final Design (1)

2

Step 2: Create a line chart showing Prototype Version vs User Satisfaction Score

X-axis = Prototype Version, Y-axis = User Satisfaction Score, line connecting points

Expected Result

Line chart showing satisfaction increasing from 5 (Sketch) to 9 (Final Design)

3

Step 3: Add text summary explaining how prototyping reduces issues and improves satisfaction

Write: 'Prototyping helps find and fix design problems early, leading to higher user satisfaction in the final product.'

Expected Result

Clear summary text below charts

4

Step 4: Combine charts and summary into a single report page

Arrange bar chart, line chart, and text summary in a clean layout

Expected Result

Report page visually showing validation benefits of prototyping

Final Result

Prototype Version  | Issues Found | User Satisfaction
---------------------------------------------------
Sketch            | ############### (15) | ***** (5)
Low-Fidelity Proto | ########## (10)      | ****** (6)
High-Fidelity Proto| ### (3)              | ******** (8)
Final Design      | # (1)                | ********* (9)

Summary: Prototyping reduces issues and raises user satisfaction before final development.

✓Issues found decrease significantly from early sketches to final design.

✓User satisfaction scores improve as prototypes become more refined.

✓Prototyping allows early detection and fixing of design problems.

✓Validating ideas with prototypes saves time and cost in development.

Bonus Challenge

Create an interactive Figma prototype that lets stakeholders click through each prototype version and see the related user feedback data.

Show Hint

Use Figma's interactive components and overlays to simulate navigation between prototype stages and display feedback summaries.
