Why does uniqueness matter when analyzing functional requirements?

Uniqueness in functional requirements is crucial because if a requirement is stated in multiple places, it can lead to inconsistencies. When a requirement is duplicated, different stakeholders might interpret or implement it differently, which can cause confusion and misalignment in the final product. This inconsistency can result in various issues during the development and testing phases, as conflicting interpretations can lead to failures in meeting the user's needs or desired functionality.

Additionally, having a single, clearly defined requirement helps ensure that all team members are on the same page, facilitating better communication and collaboration. It enables a more streamlined approach to requirements management, as changes to a single requirement can be tracked and communicated effectively without the risk of omitting or failing to update other instances of the same requirement across the documentation.

This focus on maintaining uniqueness helps ensure a clear and consistent framework upon which the development process can reliably build, ultimately improving the quality of the final product.
