Feature Prioritization and Hypothesis Testing in App Development

Introduction

For aspiring product managers aiming to succeed in FAANG interviews, it’s essential to critically analyze existing products and consider the decisions behind feature development. Interview questions may probe your ability to evaluate features and hypothesize the reasons for their inclusion. We will address the question: Which feature would you remove from your favorite app, and what do you think was the hypothesis behind creating this feature?

Detailed Guide on Framework Application

In response to this question, we can apply the HEART Framework (Happiness, Engagement, Adoption, Retention, Task Success) to identify and prioritize features in the context of user experience goals.

Happiness

Determine how the feature affects user satisfaction. Are there indications that users are unhappy or frustrated with it?

Engagement

Assess whether the feature is actually engaging users or if it’s just adding clutter to the app without any real benefit.

Adoption

Consider if the feature has a high adoption rate or if it is being ignored by most users.

Retention

Examine if the presence of the feature contributes to long-term user retention or leads to churn.

Task Success

Analyze if the feature aids in effectively completing a task or unnecessarily complicates the user journey.

Let’s consider a hypothetical scenario using a social media app:
– Happiness: Users express frustration with the app’s convoluted privacy settings feature.
– Engagement: Metrics show low engagement; users often leave the settings default.
– Adoption: Only a minute percentage of the user base interacts with these complex settings.
– Retention: There’s no correlation between the usage of this feature and user retention rates.
– Task Success: Users struggle to navigate privacy settings, leading to a poor experience.

After applying the HEART framework, we can hypothesize that the privacy settings feature was initially created to give users control over their data. However, due to its complexity, it’s not achieving its intended goals. During the interview, communicate not just what you’d change, but also provide insights on the impact it would have based on data-driven assumptions. Suggest improvements or alternatives that align with the app’s objectives.

Conclusion

Deciding to remove a feature requires careful analysis of its impacts on the user experience and overall product goals. By applying the HEART Framework, we can present a structured argument backed with data-driven insights. Practice this approach to enhance your readiness for product management interviews in FAANG companies, demonstrating your analytical abilities and user-centric focus in feature prioritization.
