Concept Testing (TED App)







Objective
         

Conceive of a new app feature that boosts retention and promotes sharing, to capitalize on TED’s massive social-media following.

My Role
         

Develop and execute a plan for concept testing of potential features to gauge desirability with users. Then, collaborate with product team and stakeholders to determine most viable concept.

Output
         

Project will result in a go-foward feature idea, manifested as proof-of-concept wireframes constituting an authentic experience to test with users (to determine MVP feature set).

Timeline
         

5 weeks (2022)


Problems & opportunities
         

TED’s social following doesn’t translate into app users


         

Feature should promote social sharing to capitalize on and activate this fanbase.





Only 2.8% of new users return after 30 days

       

Feature should incentivize repeat visits and differentiate from YouTube, where majority of TED Talks are watched.












Preliminary research
         

I began by teaming up with TED’s social team to learn everything I could about our followers. 


I also compiled app store reviews and previous research reports to help fuel ideas for an initial team brainstorm of feature ideas.





Initial feature brainstorm

         

Guided by insights compiled thus far, the team convened for an initial brainstorm of feature ideas, extracting the key benefit of each.


To narrow down ideas and/or uncover ideas we haven’t thought of, we needed to conduct concept testing.








Concept testing 

         

Key Research Questions  


         

  • What’s demand/appetite for each idea?
  • What ideas haven’t we thought of?
  • How does our audience use TED to learn? 
  • What apps do they loving using regularly? 
  • What are their expectations re: sharing?  

Recruitment
         

Since I primarily wanted to hear from TED’s casual social followers, I asked the marketing team to post a call for participants across our social channels (38M+ followers). I seized this opportunity to create the TED Community Research Panel. Rather than recruiting volunteers for this particular study, I asked followers join a database of UX research participants we will reach out to on an ongoing basis. The social post was a success, as we recruited 900+ volunteers. 




Survey & Interviews (Concept “Speed Dating)
         

To get feedback at scale, I drafted, tested and blasted a survey asking respondents to evaluate one feature idea at a time (in randomized order with no visuals) and then choose their most and least favorites. The survey also asked about their sharing habits and apps they look forward to using every day. To dig into the ‘why’ behind survey trends, I led six one-on-one interviews, asking open-ended questions adapted from the survey and explaining each feature idea to get their reaction.










Findings
         

Based on concept-testing findings, I worked with devs to plot features on a matrix weighing desirability against technical effort. 


Ruled out concepts in ‘no’ quadrants and those in ‘maybe’ quadrants that are already offered by other apps.

Honed in on concepts that reward retention, translate well to social and differentiate us from YouTube.






And the winner is... 

          

Topic Tracking—a new idea born from concept testing


See a category breakdown of content you’ve consumed in the app.

Gives users a reason to come back, since visualization changes to reflect consumption.

Users can export their visualization as a shareable graphic. 





Topics are synonymous with TED.
         

When asked to describe TED in their own words, people almost always mention the word topics. Topics are crucial to our value prop—we expose users to topics they wouldn’t normally seek out, making them more well-rounded. However, we knew our topic taxonomy was broken, since analytics showed critical navigation bottlenecks occuring on the existing topic landing page.

I collaborated across teams to restructure the IA taxonomies of 100+ topics, scaffolding them into 10 parent categories. In this polyhierarchical system, some subtopics are assigned to multiple parent categories. Negotiating the right level of granularity was a challenge, so we conducted tree testing and card sorting to determine the best labels and distribution for each category. 



Tree Testing
         

To benchmark the performance of our current taxonomy, I conducted tree testing of the existing topic IA. Participants were given the names of TED Talks and asked to choose (from a list of pre-defined topics) where they’d expect to find the Talk.



Card Sorting
         
After analyzing tree testing results, I followed up with an open card sort to see how users organize and label topics on their own, in the way that makes sense to them. Participants were given a list of TED Talks and asked to sort them into groups and come up with a name for each group. 









Devising a visual language

         

I developed a visual language by assigning colors to topics, ensuring accessibility by adhering to WCAG contrast guidelines.













Design exploration

          

Experimenting with common & fringe cases


How can I design an experience that supports the most-and least-common use cases in a way that’s easy to understand?

Analytics told us the average user would see a consumption of 16 topics. (3 topics minimum, 102 maximum)

Starting with extreme cases, I was able to rule out non-viable designs early on.

In this process, user stories and scaling issues arose (e.g. What happens when we add more categories?). To answer these questions, we needed another round of testing.











Determining MVP 

         

What functionality should we release as MVP?


         
As a user, I would like to.... 


  • Sort by consumption
  • Sort by parent category

  • See my consumption compared to all topics

  • See my consumption compared other users
  • Share/export my consumption graphic  
  • See what topics I’m missing


How should we implement MVP functionality?


         

  • How well does design maximize feature adoption?
  • How easily do users understand what they’re looking at?
  • What graphic are they most likely to share? 
  • How do users prefer to share/export? 







Next steps

         

Conduct user testing to establish MVP functionality, product roadmap and prioritized backlog

       

Create proof-of-concept wireframes that constitute an authentic experience to test with users to establish MVP design and functionality. Unmoderated testing where users are presented with concept wireframes and asked questions along the way (static or in context as user walks through prototype).  Valid or invalidate design components.
