The probability of detection helps determine how likely usability issues are to be uncovered by a specific number of participants. This metric ensures that the most critical issues are identified early, enabling teams to prioritize improvements effectively and allocate resources efficiently.
With the help of a probability of detection matrix, we discovered that the percentage of issues that would be discovered with just 5 users would be 99.67%.
To measure the overall user satisfaction with Spotify’s interface, we administered a System Usability Scale (SUS) survey. SUS is a standardized tool widely used for evaluating usability across products, generating a score from 0 to 100. Scores are typically compared against an industry benchmark of 70, where a score above 70 indicates good usability, while scores below suggest areas for improvement.
We used statistical tests to assess whether Spotify’s mean SUS score significantly differed from this benchmark.
Music Discovery and Recommendations
Spotify’s recommendation system needs improvement, as users find it repetitive and seek more personalized suggestions. Users rely on social media and friends for new music, especially for niche or emerging artists.
Playlist Management
Playlist organization is difficult due to a lack of intuitive features. Users want a more seamless way to group and move songs within playlists.
Social Features
Users enjoy collaborative playlists but find accessing friends’ profiles and activity confusing and inaccessible.
how to fix the problems we found
Simplify playlist workflows by enabling drag-and-drop song rearrangement and quick playlist assignment options.
Introduce a dedicated Friends tab to make social interactions like activity tracking and playlist sharing more accessible.
Holding the plus button on the Now Playing screen could display a pop-up that lets user quickly select the playlist they want to add the song to.
Provide song previews for easier playlist organization and encourage discovery within the platform.
what else can be done to elevate the experience
Including a "social" section where users can share songs they are currently listening to with all their friends would allow for better discovery and engagement within the app.
Similar to Soundcloud, users wished to be able to comment on specific sections of songs to share their thoughts.
Collaborative playlists are popular but have limited flexibility and engagement features. Adding options like real-time playlist updates or liking songs for the collaborators to see could make sharing music with friends more dynamic and interactive.
Lyrics for songs in foreign languages can be displayed in romanized english making it easier for non-speakers to sing along increasing global reach for artists.
