Scaled Agile Framework (SAFe) Architect Practice Test

What criteria should be considered when defining nonfunctional requirements?

1. Constrained, negotiable, repeatable, testable

2. Defined, measurable, repeatable, testable

3. Defined, negotiable, measurable, testable

4. Bounded, independent, negotiable, testable

The correct answer is: Bounded, independent, negotiable, testable

When defining nonfunctional requirements, it is vital to establish criteria that facilitate clear understanding, measurement, negotiation, and testing of these requirements. The correct choice consists of "bounded," "independent," "negotiable," and "testable," which are crucial in ensuring that nonfunctional requirements are effectively implemented and evaluated within the context of the system being developed. "Bounded" signifies that the nonfunctional requirements should have clear limits and ranges, preventing ambiguity regarding their scope. This helps the development team understand exactly what is expected without overstepping or misinterpreting the requirements. "Independent" indicates that these requirements should be able to stand alone without relying on other requirements. This independence is important because it allows teams to prioritize and address nonfunctional requirements separately from functional ones, ensuring that they receive proper attention without being overshadowed by functional requirements. "Negotiable" highlights the need for flexibility in these requirements. As projects evolve, stakeholder needs might also change; thus, having negotiable requirements allows for adjustments and refinements that enhance the overall quality and satisfaction of the produced system. "Testable" emphasizes the necessity of being able to evaluate the nonfunctional requirements through concrete testing methodologies. This ensures that all stakeholders can verify whether the requirements have been met
