A change-driven approach to business analysis and requirements management is an approach that embraces change and adapts to the evolving needs and expectations of the stakeholders1. A change-driven approach does not use a formal change control process, as it assumes that changes are inevitable and beneficial, and that they can be incorporated quickly and easily into the solution2. A change-driven approach relies on frequent feedback, collaboration, and validation to ensure that the solution delivers value and meets the stakeholder needs3. The other options are not true statements about changing requirements in a change-driven approach, as they describe aspects of a plan-driven approach, which is an approach that follows a predefined and structured process for managing changes and requires formal approval and documentation24.
