Data-driven UX: Balancing quantitative and qualitative insights for a better user experience in EFSA case-study

Darja Tokranova

In user experience (UX) research, combining qualitative and quantitative methods is one of the most effective ways to uncover both key insights and understand more subtle usability issues. Combining both approaches in a single project strengthens an evaluation by allowing the strengths of one methodology to compensate the weaknesses of the other and vice versa.

 

Recently, we in Trinidad Wiseman conducted a UX research for The European Food Safety Authority (EFSA) by using this combined methodology approach. The project explored how users navigate, search, and interact with various EFSA's web resources to access its scientific output, including research papers, scientific opinions, reports, guidance documents, and other publications.  

 

Looking to design digital services that truly meet user needs through data-driven insights? At Trinidad Wiseman, we conduct user research, business and pre-analysis, and help design user-friendly solutions – just like in this EFSA project, where we combined quantitative and qualitative methods.

Problem statement and objectives of the EFSA project

The European Food Safety Authority (EFSA) is the European Union (EU) agency responsible for delivering independent scientific advice and communicating about current and emerging risks in the food chain. 

 

EFSA contributes to protecting human life and health while considering animal health and welfare, plant health, and the environment. It provides independent and transparent scientific advice through numerous research activities, producing a large volume of scientific output relevant not only to industry players but also to academics, the press, and the general public.

 

Because of abundance of EFSA publications several platforms were created in effort to manage the important documentation and organize it in a logical and structured way: 
 

  • OpenEFSA - a portal developed by EFSA to provide stakeholders with a range of additional services and tools aimed at enhancing the transparency and accessibility of EFSA’s work. It serves as a centralized platform where all information related to EFSA’s risk assessments, including the data and studies used, is made available in one place for the first time. This initiative supports greater openness and usability for industry professionals, academics, and the public.
  • EFSA Journal - an open-access, free-of-charge online scientific journal on external platform of Wiley Online Library that publishes the scientific outputs of the European Food Safety Authority (EFSA), which is the keystone of European Union (EU) risk assessment regarding food and feed safety.
  • EFSA Publications - EEFSA produces hundreds of publications every year, both scientific and corporate, and they are gathered and categorized on EFSA webpage under Publications menu item.
  • EFSA Guidance - EU legislation and EFSA guidance documents detail how to compile dossiers for food contact material applications and what type of scientific data and other information must be included. Nested on EFSA webpage under the Guidance menu item. 

 

However, with big volumes of data comes big level of complexity that can sometimes cause users experience confusion due to occasional duplication of information, reliance on imperfect search engines, and unclear distinctions between platforms with seemingly similar goals. This can lead to frustration and inefficiencies, slowing down users' ability to navigate and access EFSA’s publications effectively, ultimately hindering productivity.

 

This is why, in 2023, EFSA conducted a user mapping and a survey to identify opportunities for optimizing the user experience across various digital platforms under its management. The survey revealed several key issues and these insights, particularly focused on Scientific Publications and Guidance documents, became our exciting new research project. 

 

 

Methodological approach

Convergent (Parallel) mixed methods design is a type of mixed methods research in which you collect quantitative and qualitative data simultaneously and analyze them separately. After the analysis, you then combine or compare the results to draw a conclusion. Convergent design is used when there is a need to compare statistical results with qualitative findings to understand the research problem better.

From the very beginning we realized that this is a perfect opportunity to apply this approach in EFSA study to ensure a well-rounded analysis. Quantitative methods would provide us measurable data, while qualitative approaches offered rich, contextual insights into user behavior and preferences.

 

Preparatory activities  

The first step in our process was to carry out preparatory activities to align all stakeholders. This involved a kick-off meeting to define project goals and expectations, studying existing materials to understand the platforms, and holding weekly meetings with the client to clarify questions and refine the project scope. These steps provided a strong foundation for the research and ensured alignment with the client’s objectives. 

 

Quantitative insights through PIWIK Analysis 

To gain an initial understanding of user behavior, we began with a PIWIK analysis. This tool provided quantitative data on the most visited pages within the platforms. By analyzing user traffic patterns, we identified areas of high engagement and potential pain points. These insights helped us prioritize specific pages and sections for further exploration. 

 

Tree Testing 

Tree testing served as a bridge between quantitative and qualitative research. This method involved evaluating the site's structure by asking users to locate items based on the website’s organization and terminology. 

 

The results highlighted areas where the site structure aligned well with user expectations and mental models of EFSA website navigation and where it fell short.  For example, users struggled to find key documents due to unclear navigation labels, which prompted recommendations for renaming and restructuring. 

 

Qualitative insights through EFSA in-house expert interviews 

The next phase involved conducting expert interviews with key stakeholders, including EFSA staff members responsible for Scientific Publications and Guidance Documents. These interviews provided deep insights into the platform's intended purpose, key challenges, and the goals of internal stakeholders. 

 

Qualitative data gathered here enriched our understanding of the broader context and helped us to compose questions and tasks for upcoming Usability testing and interviews. 

 

User testing and interviews 

User testing and interviews formed the heart of our qualitative research. During these sessions, we observed how users interacted with Scientific Publications and Guidance Documents on the website as well as how their interpreted OpenEFSA and EFSA Journal platforms. 

 

Participants were tasked with finding specific documents or completing predefined tasks, allowing us to identify usability issues and areas for improvement. In parallel, in-depth interviews allowed us to explore user motivations and preferences.

 

We asked the users about their primary goals when using this platform and how easy or difficult is it to find scientific documents, such as articles and guidelines at the current EFSA homepage? Where do users expect this information to be placed within the existing website navigation, and which repositories of documentation are redundant, irrelevant, or placed illogically?

 

These sessions provided invaluable insights into user expectations and frustrations. For instance, we discovered that users valued comprehensive search filters but found the existing search functionality cumbersome and unintuitive. 

 

 

Benefits of combining qualitative and quantitative methods

The strength of our research lay in the synergy between qualitative and quantitative methodologies. Here’s how this combination benefited the project:

 

  1. Comprehensive insights: Quantitative data from PIWIK analysis and tree testing identified broad patterns and trends, while qualitative methods, such as interviews and user testing, uncovered the underlying reasons behind these patterns.
  2. Data-driven validation: Quantitative findings provided a solid foundation for our recommendations, ensuring they were grounded in measurable evidence. At the same time, qualitative insights added depth and context to these findings.
  3. Balanced perspective: The combination of methods ensured that both user needs and organizational goals were taken into account. For example, while quantitative data highlighted heavily trafficked pages, qualitative research revealed that some of these pages were not meeting user expectations.
  4. Actionable recommendations: By integrating insights from both methodologies, we were able to deliver well-rounded, actionable recommendations that addressed both surface-level and deep-rooted issues.

Key findings and takeaways 

Some of the most significant findings from our research included: 

  • Navigation challenges: Users often struggled with unclear language of the navigation and a lack of intuitive pathways to key documents. On the other hand, some of the documents are duplicated and scattered in multiple places across the EFSA page, making it confusing to users.
  • Search functionality: The existing search tool lacked robust filtering options, and the available filters were sometimes difficult to interpret or had similar names with different meanings.
  • Labeling and tracking progress: Users would like to see the content clearly labelled with tags, color-coding or other interpretive means of UI. They would also like to see content labeled correspondingly to its status, e.g. "in-progress", "recently published", "latest version" or "soon-to-be-updated". 
     

The final step of the project involved compiling our findings and recommendations into actionable deliverables. These included: 

 

  1. A detailed final report document that outlined key findings from each approach in a great detail. Documents like this can be used for a long time after finalizing the project for further in-house developments and stakeholder consultations.
  2. An executive summary to provide people outside the project with a quick overview of the context, activities and outcomes.
  3. A Figma prototype showcasing redesigned navigation and interface elements to support the theoretical discussion of possible implementations by practical examples - a very effective way to illustrate potential solutions without overspending the budget that has proven its efficiency in the industry.
  4. A complete list of discovered issues, categorized by severity and impact with either proposed solutions or suggestions for further research and applicable methodology. Because an extensive theoretical work still has to lead to practical and actionable insights. 

 

 

Conclusion

Our UX research project demonstrated the immense value of combining qualitative and quantitative methodologies. By leveraging the strengths of both approaches, we were able to provide the client with a comprehensive understanding of user needs and actionable insights for improvement. This hybrid approach not only uncovered usability issues but also revealed opportunities for enhancing user satisfaction and engagement.

 

As the digital landscape continues to evolve, the importance of a holistic approach to UX research cannot be overstated. Combining methodologies allows organizations to create solutions that are not only functional but also resonate deeply with users’ needs and expectations.
