### Clarifying Questions
- By "car garage", do you mean a repair and service shop, or the garage where a car is parked at home?
- Is this one independent garage or a chain, and can the features be physical changes, digital tools or either?
- What should the features achieve: more customers, more revenue per visit, faster turnaround or higher customer satisfaction?
- Should the features serve car owners, the garage's own staff, or both?
### What a Strong Answer Covers
- Settling what kind of garage it is and what the features should achieve before proposing any
- A chosen customer segment and a journey map with concrete pain points at each step
- A wider list of candidate features, narrowed to exactly two with explicit criteria
- How each chosen feature works for both the customer and the mechanics, and what it costs the garage
- Metrics tied to the goal, with guardrails such as rework rate and staff time
### Follow-up Questions
- If the garage owner worries that showing customers evidence will lower approval of recommended work, how would you respond?
- How would your two features change for drivers whose car has broken down and cannot be driven?
- How would you test whether the features worked at a single garage, where a clean A/B test is hard to run?
