Close the retrospective – Reflect and thank each other. Real-World Example:?

Answer: fter noticing last-minute testing rushes, the team agrees to integrate testing into the daily workflow. Next Sprint, they try pairing QA early with devs, reducing defects by 30%.

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

1. Define the concept in one or two sentences.
2. Context — where it fits in Agile & Scrum architecture.
3. Example — a specific project, bug, or performance win.
4. 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.
