Documenting the rationale behind requirements is essential for any development team. It provides a foundational understanding that guides everyday decision-making during the implementation process. When the reasoning is clear and accessible, team members can navigate complexities and challenges more effectively, ensuring that solutions align with the original vision and goals.

This practice enhances communication within the team and fosters a collaborative environment. By referring back to documented reasons, members can make informed choices that are consistent with the project's objectives, ultimately leading to more successful outcomes. Clarity in requirements not only aids in current workflows but also serves as a valuable reference for future projects.
