Evaluate Dating App Product Changes
Evaluate Dating App Product Changes
You are a Data Scientist at Grindr, a location-based dating and social discovery application. The product team is currently evaluating several potential changes related to profile ranking, user recommendations, and monetization strategies. The app supports both free users and paid subscribers, features profile browsing via a "Grid" page, offers direct messaging, and defines a "successful connection" as two users mutually engaging in a meaningful conversation.
For each of the following proposed product changes, you are required to define:
- The primary goal of the change.
- Primary metrics to measure success.
- Secondary metrics for broader impact.
- Guardrail metrics to prevent negative outcomes.
- An appropriate experimental design.
- Key user segments for analysis.
- Major risks or biases that could affect the evaluation.
1. Reduce Profile Browsing Limit
The CEO proposes reducing the maximum number of profiles a user can browse or view in a single session from 100 to 80. How would you determine whether this change is beneficial or detrimental?
2. Choose Number of Recommendations to Show
The Machine Learning team has developed a model that identifies users most likely to achieve a successful connection with a given person. How would you decide the optimal number of recommended users to display to each person? Additionally, identify which product surfaces within the app could effectively utilize this recommendation model.
3. Test a Paid High-Connect-Probability Filter
The Machine Learning team has also created a model that predicts the probability of a successful connection between any two users. A Product Manager suggests introducing a new paid filter on the Grid page, allowing subscribers to specifically filter for profiles with the highest predicted connection probability. How would you evaluate the effectiveness of this new feature using an A/B test?
4. Evaluate a Paid “Heart” Feature
Grindr is launching a new "heart" feature, similar to a premium like or rose, which users can send to another profile. The first heart sent by a user is free, with subsequent hearts requiring payment. How would you measure the overall success of this feature? Furthermore, if the adoption rate is low immediately after launch, what steps would you take to investigate the reasons?
