Which of the following is NOT a technique for requirements elicitation?

• A. Interviews
• B. Focus Groups
• C. Delphi Method
• D. Analysis of Alternatives

Answer: (D)

The analysis of alternatives is not categorized as a technique for requirements elicitation. Instead, it is a method used for evaluating different options or solutions to meet established requirements after the requirements have already been identified. Requirements elicitation focuses on gathering and clarifying the needs and expectations of stakeholders to create a solid foundation for system requirements. In contrast, interviews involve direct conversations with stakeholders to collect their insights, preferences, and needs. Focus groups bring together a group of stakeholders to discuss and generate ideas collaboratively, ensuring diverse perspectives are captured. The Delphi method uses a series of questionnaires to gather input from experts over multiple rounds, helping to achieve consensus on requirements. These techniques are crucial for early stages of the systems engineering process, where understanding stakeholder needs and expectations is essential for developing effective and usable systems.
