Which of the following is a common elicitation technique?

Brainstorming sessions are a widely used elicitation technique because they foster a creative environment where stakeholders can freely generate ideas, express their thoughts, and articulate their requirements without the limitations of formal structures. This technique is particularly effective in gathering diverse perspectives, encouraging participation from a variety of stakeholders, and uncovering hidden needs that may not surface in more structured discussions.

In brainstorming, the facilitator's role is crucial, as they guide the session to ensure that all voices are heard, and constructive dialogue is maintained. The outcome of such sessions can lead to a rich repository of ideas that can later be refined and prioritized for further analysis and refinement, making it an indispensable tool for business analysis.

While market segmentation analysis, cost-benefit analysis, and project risk assessment are important aspects of a business analyst's toolkit, they serve different purposes and are not primarily focused on the initial gathering of ideas and requirements in the same manner as brainstorming does.
