The analyst is responsible for working through business scenarios to determine whether the defined requirements are complete, consistent, understandable, and aligned with stakeholder needs. In requirements engineering, analysts elicit, document, analyze, and validate requirements by examining user workflows, business rules, use cases, scenarios, and expected outcomes. Walking through scenarios helps reveal missing requirements, unclear assumptions, exception paths, interface needs, and conflicting stakeholder expectations. Testers may later use scenarios to design validation tests, and quality representatives may help verify requirement quality. Product developers may review feasibility and design implications. However, the primary responsibility for confirming requirement completeness through business scenario analysis belongs to the analyst because that role owns requirements analysis and stakeholder interpretation.
