Summary

Product sense round at Meta for a PM role. One question, but it had enough layers to keep me busy for the full session.

Q1

How would you design a bookshelf specifically for children? Walk through who you're designing for, what problems they face, the core design principles you'd apply, what you'd ship first, and how you'd measure whether it worked.

Suggested Approach

Start by segmenting the children's market by age and reading stage, then identify key user problems such as safety, accessibility, and engagement. Apply child-centric design principles like durability, independence, and fun, prioritize an MVP that solves the most critical pain point, and define success metrics that balance engagement with safety.

Pro tip: Anchor your design in real user research: talk to parents and observe children interacting with bookshelves to uncover latent needs. Also, consider the dual user (child and parent) and how your design addresses both their goals.

1. Define the Target User

Segment children by age (e.g., toddlers, early readers, tweens) and consider their developmental needs, reading habits, and physical abilities. Also include parents as secondary users who influence purchase and usage.

2. Identify User Problems

List pain points such as difficulty reaching books, risk of tipping, lack of organization, and declining interest. Prioritize problems based on severity and frequency for the target segment.

3. Apply Design Principles

Incorporate principles like safety (rounded edges, anti-tip), accessibility (height-appropriate, easy-to-grab), durability (child-proof materials), and engagement (colorful, interactive elements).

4. Prioritize MVP Features

Select the most impactful features to ship first, such as a low, forward-facing shelf for toddlers to see covers, with safety straps. Defer nice-to-haves like digital integration.

5. Define Success Metrics

Choose metrics like daily active use (child interacts with shelf), number of books read per week, parent satisfaction, and safety incident rate. Set targets and plan to iterate.

Key Points to Mention

  • Age segmentation and developmental stages (e.g., toddlers vs. independent readers)
  • Safety considerations: anti-tip design, non-toxic materials, rounded edges
  • Accessibility: height and reachability for children, easy-to-grab books
  • Engagement: visual appeal, interactive elements, organization that encourages reading
  • Dual-user needs: parents want organization and safety, children want fun and independence
  • Metrics: engagement (books read, time spent), safety (incidents), and parent satisfaction
