Should each requirement have a version identifier?

Having a version identifier for each requirement is essential because requirements are inherently subject to change throughout the development lifecycle. As projects evolve, team members may revise, update, or even replace existing requirements based on stakeholder feedback, technological advancements, or changing business needs. By assigning a version identifier to each requirement, teams can easily track these changes over time, understand the history and rationale behind each modification, and maintain clarity regarding which version of a requirement is currently in effect. This systematic approach fosters better communication among team members and stakeholders and helps ensure that everyone is aligned with the latest requirements, ultimately contributing to more effective project management and risk mitigation.
