Usability testing is a critical component of the UX design process. It involves evaluating a product by testing it with real users. This process helps identify usability issues, collect qualitative and quantitative data, and determine the participant's satisfaction with the product.

1. Purpose of Usability Testing

   • Identify usability problems in the design.
   • Collect data on participants' performance and satisfaction.
   • Determine if the product meets its intended purpose.

2. Types of Usability Testing

   • Moderated Testing: Conducted in person or remotely with a facilitator guiding the session.
   • Unmoderated Testing: Participants complete tasks independently, often using online tools.
   • Explorative Testing: Used in the early stages to explore user needs and expectations.
   • Assessment Testing: Evaluates a product's usability at the end of the design process.
   • Comparative Testing: Compares two or more designs to determine which performs better.

3. Usability Testing Process

   • Planning: Define objectives, select participants, and prepare tasks.
   • Conducting: Facilitate the test, observe, and record user interactions.
   • Analyzing: Review data, identify patterns, and pinpoint usability issues.
   • Reporting: Document findings and provide actionable recommendations.

You are testing a new e-commerce website to ensure users can easily find and purchase products.

1. Define Objectives

   • Ensure users can find a product using the search feature.
   • Test the checkout process for ease of use.

2. Select Participants

   • Choose 5-7 participants who represent your target audience.

3. Prepare Tasks

   • Task 1: Search for a specific product using the search bar.
   • Task 2: Add the product to the cart and proceed to checkout.

4. Conduct the Test

   • Use a tool like Zoom for remote moderated testing.
   • Ask participants to think aloud as they complete tasks.
   • Record the session for later analysis.

5. Analyze Results

   • Look for common issues, such as difficulty finding the search bar or confusion during checkout.
   • Note any positive feedback or suggestions from participants.

6. Report Findings

   • Create a report summarizing key issues and recommendations.
   • Prioritize issues based on severity and impact on user experience.

Exercise: Conduct a usability test for a mobile app that allows users to book movie tickets.

1. Define the objectives of your test.
2. Select 5 participants who frequently watch movies.
3. Prepare tasks such as finding a movie, selecting seats, and completing the booking.
4. Conduct the test and record the sessions.
5. Analyze the results and create a report with your findings.

Solution:

1. Objectives: Ensure users can easily find movies and book tickets.
2. Participants: Select individuals who use mobile apps for entertainment.
3. Tasks:
   • Task 1: Find a movie playing this weekend.
   • Task 2: Select two seats and proceed to payment.
4. Conduct: Use a tool like Lookback for remote testing.
5. Analyze: Identify issues like difficulty navigating the app or confusion during seat selection.
6. Report: Document issues and suggest improvements, such as clearer navigation or a more intuitive seat selection process.
