In systems engineering, the step that decomposes requirements to determine the functions the system must perform, producing a functional baseline, is called what?

• A. Requirements Analysis
• B. Systems Engineering Process
• C. Functional Baseline Establishment
• D. Requirements Validation

Answer: (A)

Breaking down requirements into the functions the system must perform and establishing the functional baseline is what requirements analysis does. This step takes high-level stakeholder needs and decomposes them into concrete functions and performance criteria, creating a traceable set of requirements that define what the system must be able to do. By breaking the overall mission into specific, verifiable functions, you build a functional view that guides design and later verification activities. The functional baseline that results from this analysis is the stable reference for the system’s intended behavior and its measurable capabilities. Other options refer to broader or different activities: the overall systems engineering process covers the whole lifecycle, not just the decomposition into functions; establishing a functional baseline is the outcome of this analysis, not the step itself; and requirements validation is about ensuring the requirements are correct and complete, not the initial breakdown into functions.
