Best Practices for Usability Testing

  • As part of the “Best Practices” series by Uplatz

 

Welcome to the human-centered edition of the Uplatz Best Practices series — where your product isn’t just functional, but intuitive, delightful, and user-approved.
 Today’s spotlight: Usability Testing — the key to building experiences that users love, not just tolerate.

🧠 What is Usability Testing?

Usability Testing evaluates how easy and intuitive it is for users to interact with a product or system.
 It helps uncover:

  • User confusion 
  • Navigation issues 
  • Poor task flows 
  • Accessibility barriers 
  • Feature discoverability gaps 

It’s not about bugs — it’s about behavior, satisfaction, and success.

✅ Best Practices for Usability Testing

Usability testing can make or break your UX strategy. Here’s how to do it right, fast, and continuously:

1. Define Clear Goals for Each Test

🎯 Focus on Tasks (e.g., “Can the user reset their password in 30 seconds?”)
 📋 Align With Design Hypotheses and Business Goals
 🔍 Don’t Try to Test Everything in One Session

2. Recruit the Right Participants

👤 Target Real End-Users (Not Colleagues or Engineers)
 🧠 Include Edge Cases: First-Time Users, Power Users, Accessibility Users
 🌍 Diverse Backgrounds = Better Insight

3. Create Task-Based Scenarios

📘 Ask Participants to “Book a ticket” or “Find a report”, not “Click here”
 🔁 Use Realistic Contexts and Goals
 🧭 Avoid Leading or Ambiguous Instructions

4. Use Think-Aloud Protocol

🗣️ Encourage Users to Narrate Their Thoughts
 🤯 Capture Confusion, Hesitation, and Misunderstandings in Real-Time
 📹 Record Both Screen and Facial Reactions (If Consent Given)

5. Limit Facilitator Bias

🤐 Don’t Help or Lead the User Mid-Task
 📏 Observe Before You Explain
 🧪 Keep the Environment Neutral and Comfortable

6. Test Early and Iteratively

🚀 Run Tests on Wireframes, Prototypes, and MVPs — Not Just Final UIs
 🔁 Test Before Every Major UX/Feature Change
 📆 Prefer 5–7 Participant Cycles Over Large One-Time Tests

7. Measure Success Objectively

📊 Track Task Completion Rate, Time-on-Task, Error Rate, Drop-Offs
 🧠 Supplement With Qualitative Feedback (“Was that easier than expected?”)
 📋 Use Tools Like Maze, Hotjar, Lookback, Useberry, UsabilityHub

8. Capture and Prioritize Friction Points

⚠️ Log Misclicks, Failures, Navigation Dead Ends
 🔍 Rank Issues by Frequency and Impact
 🧩 Translate Findings Into Design and Dev Tasks

9. Include Accessibility Testing

🦽 Test With Screen Readers, Keyboard Navigation, Color Blind Modes
 📏 Check for WCAG Compliance (AA/AAA)
 👥 Include Differently-Abled Users for Inclusive Design Feedback

10. Close the Loop

📢 Share Findings With Designers, PMs, and Engineers Immediately
 ✅ Validate Changes With Follow-Up Tests
 📈 Track Usability Improvements Over Product Iterations
