A Comprehensive Analysis and Enhancement Strategies for Netflix’s Recommender System: A Scenario Design Approach

1. Selecting a Recommender System

For this analysis, I will choose Netflix’s recommender system. Netflix is renowned for its sophisticated recommendation algorithms that personalize content for its users based on their viewing history, preferences, and interactions.

2. Performing Scenario Design Analysis

Given the clarified three-question framework for your scenario design analysis of Netflix’s recommender system, let’s restructure the analysis:

1. Who are your target users?

• Diverse Global Audience: Netflix caters to a wide range of users with varying preferences in genres, languages, and content types.
• Age Groups: All age groups, with specific content tailored for children, teens, adults, and different demographic segments.
• Tech-Savvy Viewers: Users who prefer streaming services for entertainment and are comfortable with digital platforms.

2. What are your users’ goals?

• Entertainment and Engagement: Users primarily seek engaging and enjoyable content that aligns with their interests.
• Discovery of New Content: Users look to discover movies, series, and documentaries that resonate with their tastes, often beyond their regular preferences.
• Convenience and Personalization: Users want a seamless experience that quickly connects them with content they will likely enjoy, without the need to extensively search.

3. How can you help them accomplish these goals?

• Enhanced Personalization: Utilizing more nuanced data (like time spent on paused content, re-watched scenes, etc.) to refine recommendations.
• User Feedback Mechanisms: Implementing more interactive ways for users to provide feedback on content (e.g., mood-based ratings, quick surveys post-viewing).
• Social Features: Introducing features like ‘watch parties’ or social recommendations where users can see what friends are watching or enjoying.
• Content Discovery Features: Adding functionalities like ‘random play’ based on mood/genre, and curated lists from filmmakers or actors to help users explore new content areas.

3. Reverse Engineering the Site

• Interface Analysis:
  • Personalized home screen with content recommendations.
  • Categories based on genres, trending content, and user-specific ‘Because you watched’ sections.
  • Rating system for users to express likes/dislikes.
• Researching Online:
  • Netflix uses machine learning algorithms that consider various factors such as watching history, user ratings, and the viewing habits of similar users.
  • The system also considers factors like the time of day, week, and device used for watching.

4. Recommendations for Improvement

• Enhance Discovery:
  • Introduce a feature for ‘surprise me’ that plays random shows/movies based on the user’s mood or preferred genres.
  • Implement a ‘watch with friends’ feature that considers combined preferences for group recommendations.
• User Interaction:
  • Encourage user ratings and reviews by making this feature more prominent and engaging.
  • Include an option for users to specify why they liked or disliked a show for more nuanced recommendations.
• Diversification:
  • Diversify content recommendation to include lesser-known shows and movies to broaden user exposure.
  • Implement a feature that allows users to explore content based on specific themes, directors, or actors.
