ASEP Requirements Definition and Analysis 3

Question 1

Which verification method is most appropriate for confirming that a system meets a quantitative performance requirement?

Accepted Answer

Test

Answer

Testing is the preferred verification method for quantitative performance requirements because it provides objective, measured evidence of compliance under controlled conditions.

Question 2

What is the significance of the 'shall' keyword in requirements statements according to systems engineering standards?

Accepted Answer

It denotes a mandatory, binding requirement that must be met

Answer

In requirements engineering, 'shall' indicates a mandatory requirement that the system must satisfy, distinguishing it from 'should' (goal) and 'may' (optional).

Question 3

During requirements elicitation, why is it important to identify and resolve conflicting requirements early?

Accepted Answer

Unresolved conflicts lead to design compromises, rework, and potential system failures if discovered late

Answer

Unresolved conflicting requirements create design problems, force costly rework, and may lead to system failures if contradictions are discovered during integration or testing.

Question 4

What distinguishes functional requirements from non-functional requirements in systems engineering?

Accepted Answer

Functional requirements describe what the system must do; non-functional requirements describe how well it must perform or constraints it must satisfy

Answer

Functional requirements define what the system must do (capabilities and behaviors), while non-functional requirements define quality attributes and constraints on how the system performs.

Question 5

What is the purpose of requirements decomposition in the systems engineering Vee model?

Accepted Answer

To progressively refine high-level requirements into increasingly detailed specifications at each level of the system hierarchy

Answer

Requirements decomposition breaks high-level requirements into progressively more detailed specifications at each hierarchical level (system, subsystem, component) along the left side of the Vee.
