What are three of the best ways to address non-functional requirements?

Options:

Handle them during a risk mitigation phase before development

Scrum is for functional, frontend development only

Include them in the Product Backlog

Before the release, they should be tested and validated in a hardening sprint

Specific expectations can be used as acceptance criteria to specific product backlog items

Important, recurring non-functional requirements can be added to the definition of done

Answer

A, E, F

It is a great way for Testers to contribute early in the Sprint as they can start creating all the tests from the beginning.

It increases collaboration between Developers as it requires Pair Programming.

It helps to identify gaps in understanding the desired behavior.

It might lead to better code as refactoring is part of the Test-Driven Development cycle.

It helps break down complex problems into smaller ones that are much easier to be tackled.

It makes Integration Tests obsolete and by doing so saves a lot of time.

Answer

C, D, E

Explanation

Detailed Explanation: Test-Driven Development (TDD) helps identify gaps in understanding by requiring tests that outline the desired behavior. Refactoring ensures better code quality, and breaking problems into smaller units makes them manageable.
