A project manager is writing the project plan and collecting the project requirements from the stakeholders as part of managing the project scope.

Inspection involves examining project deliverables to ensure they meet specified requirements and standards. While it is a valuable technique for quality assurance, it does not pertain to the initial gathering of requirements from stakeholders. Instead, inspection is used to verify that the project outputs align with the established criteria after development has begun.

Variance analysis is a technique used to compare planned project performance with actual performance, often focusing on budget and schedule discrepancies. Although it is useful for monitoring project progress and making adjustments, it does not involve gathering initial requirements but rather assesses how well the project adheres to its established parameters.

Expert judgment relies on the insights and evaluations of individuals with specialized knowledge or experience relevant to the project. While it can be beneficial in validating requirements or suggesting improvements, it is not a primary method for collecting requirements directly from stakeholders, as it typically reflects the expertise of one or a few individuals rather than a collective stakeholder perspective.
