Prioritization Case: Choosing the Feature Scope of a Minimum Viable Product
Company: Google
Role: Product Manager
Category: Product / Decision Making
Difficulty: medium
Interview Round: Other
How do you decide which features go into a minimum viable product (MVP)?
```hint Name what it must prove
An MVP exists to answer a question about the product. Decide what that question is before ranking anything, then check which features the answer actually depends on.
```
### Clarifying Questions
- Is this a brand-new product, or a new capability inside a product that already has users and a brand to protect?
- Is the MVP meant mainly to test whether people want the product, or to be the first version paying customers will depend on?
- Which constraints are fixed: a launch date, the team's size, or legal and security requirements that cannot be skipped?
- Should I illustrate the process with a specific product?
### What a Strong Answer Covers
- What the MVP must prove, stated as the riskiest assumptions about the target user and their problem.
- A repeatable method for cutting a long candidate list down to a minimal set, with explicit criteria and a way to rank borderline features.
- Separation of features needed to test the idea from those needed for trust, safety and compliance, and from nice-to-haves that can wait or be handled manually.
- Success criteria and a decision rule set before launch, and how the results shape the next iteration.
- A worked example that applies the method to a concrete product.
### Follow-up Questions
- An executive insists on a feature you cut from the MVP. How do you respond?
- After launch, early users mostly use a feature you treated as secondary. What do you do next?
- How would your approach change for an MVP released under a large, well-known brand, where a weak first version can hurt the brand?
Overview: A product management interview question about deciding which features belong in a minimum viable product. It tests whether a candidate can tie MVP scope to the assumptions it must validate, apply a repeatable prioritization method, protect trust and compliance needs, and set success criteria before launch.
