Research-based UX Design

Companion apps for chronically ill patients.

After 1 year of collaboration:

• Product discovery and delivery took only one-third of the time.
• Time-to-market for the 2 newest apps reduced to less than one-third (before: new apps took a lot of effort to build).
• Gained more returning and happier users (before: mostly satisfied users of the old apps).
• Expanded the design team from 2 to 5 product designers.

Results after 6 months of collaboration (from customer churn to halving the churn rate):

• Churn rate halved (before: many customers regularly dropped off).
• Focused on high-impact optimizations to save development resources (before: customer requests were implemented without prioritization and led to an overloaded backlog).

ProSieben/Sat.1/ZAPPN websites and apps + JoynMe app.

For Seven.One, we implemented a framework for continuous user testing to optimize the ProSieben, Sat.1, ZAPPN websites and apps, and the JoynMe app. Tasks included planning, conducting, analyzing, documenting and presenting tests. We also introduced a routine to increase efficiency and ensure continuous user feedback.

Challenges solved:

• Reduced the high effort of user tests, which were rarely done before.
• Integrated user tests into project roadmaps, where they were often done too late or not at all.
• Explored the "why" behind quantitative data, which was previously unanswered.

Measures implemented:

• Introduced a user test routine with regular meetings and task lists.
• Carried out systematic and regular user tests for continuous feedback.
• Ensured test findings are easy to find and understand for efficient decisions.
• Produced short highlight reels to share key insights with product teams, stakeholders and management.

User test preparation included:

• Recruiting suitable test users for a representative group.
• Planning the entire process and tracking tasks and milestones with a testing planning checklist.
• Creating a user test overview file with target group, methods and expected results.
• Writing a detailed interview guide with relevant questions and scenarios.
• Creating and refining prototypes for accurate testing and useful feedback.
• Checking all technical and organizational setups with a pre-testing day check-up checklist.

Test execution included:

• Introducing participants and explaining procedures to create a relaxed test atmosphere.
• Conducting the test in a structured way based on the interview guide.
• Observing interactions and taking detailed notes.
• Getting direct feedback from participants at the end.

Analysis and reporting included:

• Consolidating and systematically organizing all collected data.
• Analyzing data to identify patterns, issues and insights.
• Summarizing key findings clearly and concisely.
• Maintaining a research repository with all relevant research data and documents.
• Creating a detailed report and presenting results and recommendations to the team, stakeholders and management.

Creating highlight reels included:

• Selecting key scenes or statements that show valuable insights or issues.
• Highlighting important interaction patterns and user behaviors.
• Summarizing the main findings and recommendations clearly.
• Producing short video summaries for efficient communication of test aspects.
