The correct answer is C. Functional decomposition. Functional decomposition is the technique of breaking a system or product into its constituent components and documenting what each component does.

Requirements Analysis and Design Definition

Question

Ben is the business analyst for his organization. Ben is currently working on a solution to improve a laser printer. He has taken the laser printer apart, identified each component, and documented each component's purpose. What type of requirements organization is Ben doing in this scenario?

Why each option

Functional decomposition is the technique of breaking a system or product into its constituent components and documenting what each component does.

AProcess modeling

Process modeling captures workflows and sequences of activities, not the physical or logical breakdown of a product's components.

BData modeling

Data modeling organizes and defines data structures, entities, and their relationships, which is unrelated to identifying hardware components.

CFunctional decompositionCorrect

Functional decomposition involves systematically disassembling a system, product, or process into its individual parts to understand their roles and relationships. Ben's action of physically disassembling the printer and cataloging each component's purpose is a textbook application of this technique. It is used in business analysis to model scope, identify system boundaries, and clarify how sub-components contribute to overall functionality.

DScope modeling

Scope modeling defines the boundaries of a solution or project, not the internal structure of an existing product's components.
