CAPM Practice: Determine how to gather requirements

Focus groups gather small groups of similar stakeholders to discuss topics. Group dynamics — where one person's comment sparks another's idea — can surface requirements and priorities that individual sessions wouldn't reveal.

**Why not B:** Focus groups are not the fastest method for gathering requirements from large populations. Surveys and questionnaires are far more efficient for reaching large groups quickly. Focus groups are small-group sessions (typically 6-12 participants) that prioritize depth of discussion over speed or scale.

**Why not C:** No single elicitation technique eliminates the need for all others. Focus groups complement interviews, surveys, observation, and document analysis. A well-rounded requirements gathering approach uses multiple techniques to ensure completeness and reduce blind spots.

**Why not D:** Focus groups produce qualitative insights, not statistically valid quantitative data. The small, non-random sample sizes used in focus groups cannot support statistical inference. Surveys with proper sampling methodology are the appropriate tool for generating statistically valid data on stakeholder preferences.
