UX research: What is it?

Before we explore UX research methods, it's important to understand what is UX research. It's the process of understanding how users discover, interact, and use products to better our own as UX/UI designers.

Through user surveys, focus groups, usability testing, and A/B testing, UX research collects data to understand user behaviors, needs, and motivations.

This data is crucial for forming insights that help design and develop products and services centered around the user.

However, becoming skilled in UX research involves more than just understanding its principles. It's a skill that combines a deep understanding of user behavior and the ability to interpret data effectively.

Strong communication skills are another must-have, as presenting your findings and recommendations to your stakeholders is crucial to getting their buy-in.

What is primary and secondary research?

Primary and secondary research are two fundamental approaches to gathering information. Each serves a distinct role in the research process.

Primary research generates data through UX research methods, whether user interviews, surveys, and/or usability. Secondary research summarizes all the data and notes you've gathered in the primary research process.

Primary research

Primary research is key to gathering fresh, specific data directly related to your objectives. Both qualitative and quantitative UX research methods fall into primary research.  This method involves obtaining first-hand information, which means the data is original and tailored to your specific study needs.

For example, you are designing a music-listening app. In this stage, you can conduct the following primary UX research methods:

• Surveys: To gather information on user demographics, music preferences, and listening habits.
• User interviews: Potential users to understand their needs, frustrations, and desires on the existing music apps they use.

Secondary research

Secondary research refers to synthesizing and interpreting data collected through primary research methods. This phase is crucial for transforming raw data into actionable knowledge.

Here's a look at different types of secondary research methods in UX research:
‍

1. Affinity mapping

This method involves organizing qualitative data into groups or themes.

In the same example, you can use affinity mapping to categorize the information you've gotten from the surveys and user interviews into themes like 'Ease of Use,' 'Music Discovery,' 'Playlist Management,' and 'Social Sharing.'

2. Customer personas

Developing customer personas is a way to create representative profiles of key user types.

Based on the primary research data, you create several customer personas:

• "Casual Listener Laura" – A user who enjoys background music while working or relaxing, values ease of use, and prefers curated playlists.
• "Audiophile Alex" – A music enthusiast who values high-quality audio, diverse music libraries, and advanced search features.
• "Social Sharer Sam" – A user who enjoys sharing music with friends and discovering new tracks through social features.

These personas help the design team focus on specific features and interfaces that cater to different user types. For instance, creating simple, user-friendly interfaces for Laura while offering advanced features for Alex.

3. Customer journey mapping

This involves creating a visual or narrative representation of the user’s experience with a product or service over time.

For Laura, the journey might start with opening the app, easily finding a suitable playlist, and playing music with minimal interaction.

On the other hand, Alex's journey involves exploring different genres, searching for high-fidelity tracks, and customizing playlists.

These maps highlight critical touchpoints, such as the ease of finding music, the quality of audio streaming, and social sharing capabilities. The team identifies that a streamlined onboarding process is essential for first-time users and that personalized recommendations can significantly enhance user engagement.

Comparative research techniques

Comparative research techniques are a systematic approach used in various fields to compare two or more entities, ideas, systems, or phenomena.

This method is used to find out what is similar and different between things, understand how and why they work, or see which works better or has more impact.

Here are two examples of comparative research:

1. Heuristic evaluation

What is it: A systematic approach to reviewing a product and comparing it against established usability principles.

By comparing a product's design against recognized best practices, it helps quickly identify areas where the user experience can be improved.

Consider your music listening app being evaluated using Nielsen-Molich's Heuristic Evaluation. In this scenario, you would review the app against Nielsen's heuristics to identify potential usability issues.

Here's how it might go:

1. Visibility of system status: Check if the app shows what’s playing and if it’s clear when a song is paused, playing or loading. This will determine if the user knows what's happening in the app.
2. Match between the system and the real world: Assess if the app uses familiar icons and terms, like a play button or the word 'Playlist'.
3. User control and freedom: Look for features like the back navigation and the ability to quickly stop or skip songs so that users don't feel stuck or frustrated.
4. Consistency and standards: Check if the app follows standard conventions, such as tapping a song to play it or swiping to add it to a playlist.
5. Error prevention and recognition: Review if the app has clear error messages (like when a song can't be played) and if it prevents errors (like accidentally deleting a playlist).
6. Recognition rather than recall: Ensure users don’t have to remember information from one part of the app to another. For example, if they add a song to a playlist, that action should be visually confirmed.
7. Flexibility and efficiency of use: Look for shortcuts and customization options, such as creating quick playlists or setting favorite songs.
8. Aesthetic and minimalist design: Determine if the app's design is not cluttered and that all elements on the screen serve a purpose.
9. Help and documentation: Finally, they check if the app provides easily accessible help or FAQs for new users.

2. Competitive analysis

What is it: This method compares your product's usability and features with those of competitors. A competitive analysis can help you determine where your product stands in the market, and identify opportunities to innovate and differentiate it from the others.

For example, you've been tasked to conduct a competitive analysis on a travel booking app that your team is building. This requires a deep dive into other existing listening music competitors, such as Spotify and Apple Music.

Here are some aspects to consider:

1. Design & navigation: Compare how each app handles the user interface and ease of navigation. Which takes you from login to music playing the quickest and most effortlessly?
2. Feature showdown: List and contrast the features. Who leads with unique offerings like exclusive content or personalized playlists?
3. Speed test: Check which app is faster and more responsive. Speed is key for a smooth experience.
4. User reviews: Scan what users are saying. Identify what they love and loathe, and spot opportunities for your app.
5. Value for money: Evaluate which app offers more for the price - think subscription costs versus features like ad-free listening or offline play.

‍

How to choose the right UX research method

The right UX research method is crucial to gaining valuable insights and driving your product's success.

Here's a structured approach to choosing the best UX research method:
‍

1. Define your objectives

Are you trying to understand user behavior, test a new feature, or evaluate the usability of your product? Different objectives will require different research methods.
‍

2. Consider the stage of your product

The stage of your product development plays a crucial role. For instance, early stages may benefit more from exploratory methods like interviews or surveys to understand user needs, while later stages might require usability testing to refine the product.
‍

3. Understand your users

Tailoring your research method to your audience is key. Younger demographics might be more responsive to online surveys, while in-depth interviews could be better for engaging with professionals for a B2B product.
‍

4. Check the availability of resources

Assess your resources in terms of time, budget, and expertise. Some methods require more resources than others. For instance, usability testing might need more specialized skills and tools compared to conducting surveys.
‍

5. Plan for secondary research

Consider how you will analyze the data. The chosen method should align with your ability to effectively analyze and interpret the results.
‍

6. Stay flexible and iterative

Be prepared to adapt your approach based on initial findings. UX research is iterative, and initial results might lead you to adjust your methods.

‍

Best practices in applying UX research methods

Every design project is unique, but there are best practices that can improve your UX research process.

Let's go through some of them:
‍

1. Start with your problems, not ideas

Focus on identifying and understanding the core problems before jumping to solutions. This approach ensures that your research is driven by genuine user needs rather than preconceived ideas. Start by asking questions like "What problems are our users facing?" rather than "How can we implement this feature?"
‍

2. Build your foundational report

Create a foundational report as a central repository for all your research findings. This report should include user personas, pain points, user needs, and behavioral patterns. This will become a great reference point for your team so that everyone clearly understands the user insights.
‍

3. Know your priorities

Assess which areas will have the most significant impact on user experience and align with your business goals. Frameworks like the Eisenhower Matrix can help you categorize research tasks based on urgency and importance. This helps allocate resources effectively and focus on research that will provide the most value.
‍

4. Apply the mixed-methods approach

Combine qualitative methods like interviews and focus groups with quantitative methods like surveys and analytics. This mixed-methods approach gives both depth and breadth to your findings.
‍

5. Regularly validate assumptions

What you assume about your users may not always be accurate. Regular validation ensures your product development is on track with user needs.
‍

6. Iterate your findings

UX research should be an iterative process. Use the findings to make improvements, then test and research again. Each cycle brings you closer to a more refined and user-friendly product.
‍

7. Involve stakeholders

Keep stakeholders involved in the UX research process. Their insights and feedback can provide additional perspectives and help align the research with business objectives.
‍

8. Consider ethics

Always conduct research ethically. Ensure user consent and privacy are maintained, especially when dealing with sensitive user data.
‍

9. Communicate clearly

Communicate your findings clearly and effectively to your team and stakeholders. Use visual aids like graphs and charts for quantitative data and storytelling for qualitative insights.
‍

10. Focus on user-centricity

Finally, always keep the user at the center of your research. Every method, analysis, and conclusion should aim to improve the user experience.
