Ideation & Validation Process

Phase 1: Problem Identification

  1. Understand the Problem
    • Define context and constraints.
    • Study the audience and gather qualitative and quantitative data.
    • Review similar issues, companies, and features.
    • Gather team input and align on the problem and audience.
    • Draft and refine a user story map.
    • Discuss engineering constraints, prioritize, and define the MVP and long-term goals.
    • Determined the hypothesis, scope, and schedule for the project.

Phase 2: Idea Generation

  1. Brainstorm & Concept Development
    • Run a Crazy 8s session to gather ideas from all teams.
    • Create and refine concepts.
    • Develop early responses through concept sketching and wire-framing.
    • Align with stakeholders on what to test
Phase 3: Prototyping & Testing

  1. Create & Test Prototypes
    • Build workflows and create high-fidelity prototypes.
    • Prototype interactions to test usability.
    • Develop a test script and conduct user tests.
    • Synthesize results, update the user story map, and iterate based on feedback.
    • Conduct additional tests and make iterations based on feedback.
    • Refine the design through repeated testing and feedback until the audience responds well to the proposed experience.

Phase 4: Delivery & Improvement

  1. Finalize & Review
    • Review the prototype with engineering to finalize requirements.
    • Conduct additional tests and make necessary iterations based on feedback.
    • Create and finalize the high-fidelity prototype with the design system.
    • Q&A
  2. Post-Delivery Analysis
    • Conduct a full analysis of initial results post-shipment.
    • Interpret results, discuss with stakeholders, and structure additional tests.
    • Continuously improve the design based on feedback and analytics.
    • Begin the investigation phase of the product experience again, continuously improving the design.




Solution A

Improve Search answers by using AI to serve reliable and accurate content to user queries. 

  • Fine tuned Chat GPT with our question and answer library transcripts, and created a prompt that ensures all the answers are generated only from Roon’s medically vetted database.
  • Created an interface that allows users to ask a question to Roon and get answers with sources to our proprietary medically vetted video content
  • Added an entry point from home
  • Added an entry point from search





    Before






    User Problem
    Roon has medically vetted content, but they are hard to find from the current navigation







    User Problem
    Users can ask doctors questions, but wait times for answers are too long.










    User Problem
    Some users don’t even know where to start, what to ask, need to be guided. 






    User Problem
    Users want trustworthy answers to their medical questions.










    Solution B

    Make Search more accessible from high-traffic pages and improve navigation and query suggestions.


    • Merged topics tab and search tab and called it explore with search icon.
    • Made search function accessible from tab bar 
    • Redesigned a tabbed search landing page, where users can get topic, subtopic and expert match





    Before






    User Problem
    The search function is confusing, and difficult 
    to find. 







    User Problem
    There's no way to search for experts, topics, or subtopics. Many users are unaware of the different types of content available.







    Impacts & ResultsAI-powered Search is helping users ask meaningful questions and find answers with deep medical expertise. 

    search




    We observed a 24% increase in users clicking through a question instead of closing the Search page, well above our original goal to reduce Search drop off by 20% 


    We observed a 9% increase in search page visits by active users.


    We observed an 85% decrease in users asking doctors questions, as AI now answers most questions accurately.


    ai



    80% of AI answers are voted up, indicating users are finding answers they need with the AI-powered ask. 
     


    AI-powered ask e has increased by 6.29% since it’s launch on March 2024.


    AI-powered ask has been stealing traffic from global search.


    Users ask 2-3 questions a day to AI-powered ask. 



    Lessons Learned
    • AI can be used to generate questions that users are likely to ask, that can be displayed as “Related Questions” suggestions to make search more efficient.
    • Design with search and AI computation times in mind, using motion to mask delays.
    • Clearly communicate AI limitations to users, preparing them for potential hallucinations and misleading answers.
    • Educate users on how to effectively use AI to achieve the best results, focusing on instructional guidance.
