How do you prioritize items in the Product Backlog? Techniques to prioritize: ● MoSCoW (Must, Should, Could, Won’t) ● Kano Model (Basic, Performance, Delighter) ● Value vs. Effort Matrix ● Weighted Shortest Job First (WSJF) in SAFe Factors to consider: ● Customer value ● Business impact ● Risk reduction ● Dependencies Follow On: ● Technical feasibility Example:
Answer: travel app team uses Value vs. Effort to prioritize. “In-app booking” has high value and moderate effort, while “Flight status tracking” has high effort and low impact — so the former gets scheduled first.
What interviewers expect
- A clear definition tied to Agile in Agile & Scrum projects
- Trade-offs (performance, maintainability, security, cost)
- When you would and would not use it in production
Real-world example
In a production Agile & Scrum application, teams apply this when handling user-facing features or integration boundaries. For example, you might use it during a sprint where reliability and observability matter—logging metrics, validating edge cases, and documenting the decision in an ADR so future developers understand why the approach was chosen.
How to explain in the interview
- Define the concept in one or two sentences.
- Context — where it fits in Agile & Scrum architecture.
- Example — a specific project, bug, or performance win.
- Trade-off — what you gain vs what you sacrifice.
Tip: Practice aloud on Toolliyo mock interview or the Interview Q&A section before your real interview.
