1️⃣ What is User Testing?

User testing evaluates a product’s usability by having actual users perform tasks while researchers observe and analyze behavior. The goal: detect usability issues early and make data-driven design improvements.

2️⃣ Benefits of User Testing

  • Validate Design Decisions – Confirm if navigation, visuals, and interactions meet user expectations.
  • Improve Accessibility – Identify barriers for users with disabilities.
  • Boost Conversion Rates – Remove friction points to increase engagement and sales.
  • Save Costs – Early fixes are far cheaper than post-launch changes.

3️⃣ User Testing Methods

  • Moderated Testing: Live sessions where a facilitator guides participants.
  • Unmoderated Remote Testing: Users complete tasks independently; tools record screens and clicks.
  • A/B Testing: Compare two versions of a design to see which performs better.
  • Accessibility Testing: Ensure screen-reader compatibility, color contrast, and keyboard navigation.

4️⃣ Example Project: E-Commerce Checkout Flow

Scenario: Improving a checkout page for a fashion e-commerce website.

Process

  1. Recruit Participants – Diverse demographics, including users with assistive tech.
  2. Set Tasks – “Add an item to cart and complete purchase.”
  3. Observe & Record – Used Maze for remote session recordings and heatmaps.
  4. Analyze Results – Found issues in coupon code entry and payment step clarity.
  5. Iterate – Redesigned checkout flow for better guidance and fewer form fields.

Outcome: Cart-abandonment rate dropped by 15% after implementing changes.

5️⃣ Accessibility Best Practices

  • Provide captions for all testing videos.
  • Include participants with disabilities for inclusive insights.
  • Verify color contrast and keyboard operability in prototypes.
  • Test across devices: desktop, tablet, and mobile.
