A business analyst needs to ensure the project team understands the most critical roles and responsibilities within the requirements change process. Which responsibility is the most important?

Approving a change is an outcome of the process and requires analysis first; it is an authority function, not the most critical analytical responsibility.

Discussing a change is a collaborative activity that feeds into analysis but does not itself produce the structured impact assessment required.

Reviewing a change is part of the evaluation process but is less rigorous and comprehensive than formal impact analysis.

Analyzing a requirements change means assessing its impact on scope, schedule, cost, quality, and dependent requirements - this is the critical input that informs all subsequent decisions. Without a thorough analysis, reviewing and approving a change is uninformed and risks introducing defects, scope creep, or misaligned deliverables. The BA's core value in change management lies in this analytical capability, not simply in facilitating discussion or rubber-stamping decisions.
