Key Takeaways
1. Usability testing is essential and simpler than you think
Testing with one user is 100% better than testing with none.
Why test? Usability testing is crucial for improving websites and applications. It involves watching people try to use what you're creating, with the intention of making it easier to use or proving that it is easy to use. The process is simpler than most people think and can be done effectively with minimal resources.
How to test: The basic process involves:
- Recruiting participants
- Creating tasks for them to perform
- Observing their behavior and listening to their thoughts
- Analyzing the results and making improvements
Don't be intimidated by the perceived complexity or cost. Even informal, small-scale testing can yield valuable insights and lead to significant improvements in user experience.
2. Start testing early and often with just three users per round
The purpose isn't to prove anything; it's to get insights that enable you to improve what you're building.
Early and frequent: Begin testing as soon as you have something to show, even if it's just rough sketches or wireframes. Conduct tests regularly, ideally once a month, to continually improve your product throughout the development process.
Three users per round: This approach allows you to:
- Identify major usability issues quickly
- Keep the process manageable and cost-effective
- Iterate and improve more frequently
By testing with just three users, you can uncover most of the significant problems without overwhelming your team or budget. Remember, it's better to test frequently with fewer users than to conduct large, infrequent studies.
3. Recruit loosely and focus on observing user behavior
Recruit loosely and grade on a curve.
Flexible recruiting: Don't obsess over finding perfect matches for your target audience. Most usability issues can be identified by almost anyone, and sometimes outsiders can provide valuable fresh perspectives.
Focus on behavior: The key is to observe how people interact with your product, not to gather opinions or demographic data. Pay attention to:
- Where users struggle or get confused
- What they overlook or misunderstand
- How they navigate and make decisions
Remember that you're testing the product, not the users. Be empathetic and make participants feel comfortable to ensure honest, natural behavior during the test.
4. Create realistic tasks and scenarios for testing
If you're going to watch people try to use what you're building you've got to give them something (or some things) to do.
Task selection: Choose tasks that are:
- Critical to the success of your product
- Likely to reveal usability issues
- Representative of real-world usage
Scenario creation: Develop clear, concise scenarios that provide context without giving away solutions. Avoid using specific words or phrases that appear in the interface, as this can turn the task into a simple word-finding exercise.
Example task: "You want to book a flight to New York for next month. Find a suitable option and begin the booking process."
By creating realistic tasks and scenarios, you'll gain more accurate insights into how users interact with your product in real-world situations.
5. Facilitate tests by encouraging users to think aloud
The combination of watching them use the thing and hearing what they're thinking while they do it allows you to see your site through someone else's eyes (and mind).
Think-aloud protocol: Encourage participants to verbalize their thoughts, actions, and feelings as they use your product. This provides invaluable insights into their decision-making process and mental models.
Tips for effective facilitation:
- Remind users to think aloud throughout the test
- Ask open-ended questions to prompt more detailed responses
- Avoid leading questions or providing hints
- Maintain a neutral tone and body language
By mastering the art of facilitation, you'll be able to extract more useful information from each test session and gain a deeper understanding of your users' experiences.
6. Involve the whole team in observing and debriefing
Seeing is believing.
Team observation: Encourage all team members, including designers, developers, managers, and stakeholders, to observe test sessions. This creates a shared understanding of user needs and challenges.
Benefits of team involvement:
- Builds empathy for users
- Reduces reliance on secondhand information
- Fosters a user-centered design culture
Effective debriefing: Hold a debriefing session immediately after testing to:
- Identify the most critical issues
- Prioritize problems to address
- Brainstorm potential solutions
By involving the entire team in the testing process, you'll increase buy-in for user-centered design and ensure that insights are quickly translated into actionable improvements.
7. Fix the most critical issues with the least effort
Focus on fixing the most serious problems first.
Prioritize ruthlessly: Concentrate on addressing the most severe usability issues that affect the largest number of users. Resist the temptation to tackle minor problems or implement perfect solutions.
Strategies for efficient problem-solving:
- Tweak, don't redesign: Make small, targeted changes instead of overhauling entire sections
- Remove before adding: Often, simplifying or removing elements can solve problems more effectively than adding new features
- Implement quick fixes: Don't wait for a major redesign to address critical issues
By focusing on high-impact, low-effort solutions, you'll make significant improvements to your product's usability without getting bogged down in perfectionism or scope creep.
8. Remote testing offers convenience and flexibility
Overall, I'd say remote testing gives you about 80% of the benefits of a live test with about 70% of the effort.
Benefits of remote testing:
- Easier recruitment of participants
- No travel required
- Flexible scheduling
- Similar results to in-person testing
Considerations:
- Slightly less control over the testing environment
- Potential for technical issues
- Less non-verbal communication
Remote testing tools:
- Screen sharing software (e.g., GoToMeeting)
- Video conferencing platforms
- Specialized remote usability testing services (e.g., UserTesting.com)
While remote testing may not fully replicate the in-person experience, it offers a convenient and cost-effective alternative that can yield valuable insights, especially when geographic or logistical constraints make in-person testing challenging.
