What term refers to a collection of items functioning as a whole to satisfy a documented requirement?

• A. System
• B. Process
• C. Circuit
• D. Assembly

Answer: (A)

The idea here is a collection of parts that work together to deliver a defined outcome. A system is made up of interrelated components—hardware, software, people, and processes—that interact to meet a documented requirement. It’s not just about individual pieces, but how they function as a cohesive whole to achieve a specific purpose.

A process, by contrast, is the sequence of actions used to perform a task, not the assembled set that produces the result. A circuit refers to a specific electrical loop, a narrow, technical element. An assembly is simply a physical grouping of parts, which may be part of a larger system but doesn’t by itself convey the idea of functioning as a whole to satisfy a requirement.

Thus, the term that best fits a collection of items functioning as a whole to satisfy a documented requirement is system. For example, an aircraft’s propulsion system integrates engines, controls, and interfaces to meet performance and safety requirements.
