After elicitation activities are performed, the purpose of comparing the results is to ensure consistency and accuracy across information gathered from various stakeholders or techniques. This comparison helps in identifying discrepancies, resolving conflicting inputs, and validating that stakeholder perspectives are properly reflected.
