Children's Bookcase Concept: Product Design From User Needs to a First Version
Company: Salesforce
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are asked to design a bookshelf for children. Decide which children it serves first, what it does that an ordinary bookshelf does not, and what goes into the first version.
```hint Watch one child use a shelf
Picture a child of a particular age picking a book, taking it out and putting it back on an ordinary shelf, and note each step where that fails for the child or for the adult in the room.
```
### Clarifying Questions
- Which children should it serve: toddlers who cannot read yet, children starting to read, or older kids with growing collections?
- Is the goal to sell a profitable piece of furniture or to get children reading more, and how should the two be weighed?
- Are we a furniture maker limited to physical materials, or can the design include electronics or an app?
- Is it for family homes only, or should classrooms and libraries be considered too?
### What a Strong Answer Covers
- A chosen age group and setting, with reasons for choosing it over the others
- The separate needs of the child who uses the shelf and the adult who buys, assembles and looks after it
- Pain points with ordinary bookshelves, safety among them, turned into specific design features
- A prioritized first version, with what is deferred and why
- Success metrics with guardrails, and the main risks
### Follow-up Questions
- How would the design change if a school, not a family, were the buyer?
- Children outgrow furniture within a few years. How would you keep the product useful, and does that change the business model?
- How would you test the concept with children and parents before committing to manufacturing?
Overview: A product design interview exercise asking the candidate to design a bookshelf meant for children. It tests choosing an age group, balancing the needs of the child who uses it and the adult who buys it, turning safety and usability pain points into features, and defining success metrics.
