Grocery Store Strategy: Diagnosing and Sustaining a Sudden 500% Revenue Surge
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
You own a supermarket, and its revenue has just grown by 500%. What do you do now?
```hint Ask why before acting
Think about what would have to be true for a single grocery business's sales to multiply this much, and whether it will still be true next quarter.
```
### Clarifying Questions
- Over what period did revenue grow 500%, and is it still climbing or has it leveled off?
- Is this one store or a chain, and did the growth come from the existing store or from new locations or channels such as delivery?
- Do we already know what caused the growth, or is finding the cause part of the task?
- Has profit grown along with revenue, and is the store already hitting limits such as empty shelves or long checkout lines?
### What a Strong Answer Covers
- Checking that the number is real and breaking it down by shoppers, visits, basket size, category, time and channel to find the cause
- Judging whether the cause will last, and letting that decide how much fixed cost to take on
- Protecting the operation right away: stock, staffing, checkout capacity, suppliers, cash flow and margin
- A sequenced plan for keeping the new shoppers and growing further, with metrics that show whether it is working
- Risks such as expanding on a temporary spike, worse service for loyal shoppers and dependence on one source of sales
### Follow-up Questions
- Suppose almost all of the growth came from one large business customer. How does your plan change?
- A few months later revenue falls partway back toward its old level. Was your plan wrong, and what do you do next?
- How would you choose between opening a second store and launching delivery from the current one?
