In Requirements Life Cycle Management , the task that extends the value of requirements beyond the current initiative is Maintain Requirements . This involves keeping requirements accurate, up to date, and available for reuse in future initiatives. Reusable requirements reduce the need for rework and improve organizational efficiency.
