Starbucks Store Clustering Strategy: Explaining Locations on Opposite Sides of a Street
Quick Overview
A product strategy question asking why Starbucks would run two stores facing each other across the same road instead of one. It tests reasoning about traffic direction, peak-hour capacity, competitive preemption and cannibalization, and whether a candidate can say when clustering locations stops paying off.
Starbucks Store Clustering Strategy: Explaining Locations on Opposite Sides of a Street
Company: Google
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Some Starbucks locations come in pairs: one store on each side of the same road, close enough that a customer at one can see the other. Explain why Starbucks would choose to run both stores instead of a single one at that spot.
Cover what the second store gains, what it may take from the first, and the conditions under which running the pair makes business sense.
```hint Follow one customer's commute
Picture a driver who wants coffee on the way to work and spots a store on the far side of the road. What does reaching it cost them, and where does their purchase go if Starbucks is only on one side?
```
### Clarifying Questions
- Is this a busy multi-lane road where crossing or turning across traffic is slow, or a walkable street that is easy to cross?
- Are the two stores the same format, or is one a drive-thru and the other a café or a counter inside another business?
- Are both stores company-operated, or could one be licensed to another operator with different economics?
- Should I only explain the rationale, or also judge whether it is a good strategy and how to verify it?
### What a Strong Answer Covers
- How a coffee store's revenue depends on passing traffic, the share who stop, order value and peak-hour capacity
- Customer-side reasons the second store wins sales: direction of travel, the cost of crossing, waits at peak
- Business-side reasons: denying the site to competitors, brand visibility and shared operating costs
- Cannibalization: how to tell whether the pair adds net sales or only splits existing ones
- The conditions under which twin stores are a mistake
### Follow-up Questions
- How would you measure how much of the new store's sales came out of the original store?
- What evidence would lead you to close one of the two stores?
- How do mobile ordering and delivery change the case for placing stores on both sides of a road?
