Which technique is commonly used during the requirements elicitation phase?

Interviews are a commonly used technique during the requirements elicitation phase because they facilitate direct, in-depth conversations between the business analyst and stakeholders. This method allows the analyst to gather detailed information about the stakeholders' needs, preferences, and expectations. Through open-ended questions and follow-up inquiries, interviews provide the opportunity to explore complex topics and clarify any ambiguities in the requirements. The personal interaction can lead to insights that other techniques might miss, resulting in a deeper understanding of the requirements and fostering a collaborative atmosphere.

Surveys, while useful for gathering quantitative data from a larger audience, may not provide the same depth of insight as interviews. Focus groups can gather diverse perspectives but can be less effective in addressing individual concerns or nuances. Case studies typically analyze past projects or scenarios rather than actively eliciting current requirements. Hence, interviews stand out as a preferred and effective method during the requirements gathering process, promoting thorough understanding and stakeholder engagement.
