Which of the following is not a function of system design?

• A. Defining the architecture
• B. Defining the components
• C. Demanding actions and answers
• D. Satisfying specific requirements

Answer: (C)

System design focuses on shaping how the system will be structured to meet its needs: choosing an architecture that defines major subsystems and their interactions, deciding which components will exist and how they will cooperate, and ensuring the design meets the specified requirements—functional, performance, reliability, security, and interoperability. Demanding actions and answers doesn’t describe a design activity; it sounds like prescribing user interactions or forcing specific responses, which belongs to interaction design or requirements specification, not the act of designing the system’s structure and components. So that statement does not fit as a design function. The other options—defining the architecture, defining the components, and satisfying specific requirements—are core design tasks that translate requirements into a workable structure and set of components.
