Rethinking the Microwave Oven Around One User Group's Biggest Frustrations
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You are a product manager asked how you would redesign the microwave oven. Decide what the redesign should achieve, pick a group of users to design for, find what frustrates them about microwaves today, and propose and prioritize changes along with how you would measure success.
```hint Follow one use
Take one everyday task the group you chose relies on the microwave for, and walk through it from choosing a container to eating, marking every point where the user has to guess or check.
```
### Clarifying Questions
- Is this a countertop microwave for homes, a built-in or over-the-range model, or a commercial unit for offices and restaurants?
- What business problem is the redesign meant to solve: declining sales, a new premium line, or a first product in a category new to us?
- Is the redesign limited to the controls and software, or can it change the hardware, size and price?
### What a Strong Answer Covers
- A goal for the redesign tied to why people buy, or put off buying, a new microwave
- User groups compared by how they use a microwave, with one chosen and the reason
- Pain points from that group's actual use, ranked by frequency and severity
- Solutions weighed on impact, effort, unit cost and safety, with a first version chosen
- Success metrics and how each would be collected for an appliance, with guardrails and the main risks
### Follow-up Questions
- If people tend to replace a microwave only when the old one stops working, how does that change your launch plan and the way you read sales?
- How would you test the core feature before investing in production hardware?
- What would convince you to add internet connectivity, and what would make you leave it out?
