What is the method to track changes in requirements across different phases of development?

To track changes in requirements across different phases of development, organizations often use a requirements management tool that allows for version control and traceability. This involves documenting each requirement with unique identifiers and linking them to corresponding design, implementation, and testing artifacts. Regular reviews and change control processes ensure that all stakeholders are informed of modifications, while maintaining an audit trail for accountability. Additionally, agile methodologies often incorporate user stories and backlogs to facilitate ongoing adjustments throughout the development cycle.
