Which of the following is a characteristic of an unambiguous relationship in requirements?

An unambiguous relationship in requirements is characterized by being clear and precise. This means that the relationship can be understood in only one way, leaving no room for misinterpretation. Clarity and precision are essential in requirements documentation because they ensure that all stakeholders have the same understanding of the relationships between different requirements, which is critical for successful project outcomes.

In contrast, multiple interpretations of a relationship would indicate ambiguity, which can lead to confusion and disagreement among stakeholders. Similarly, if the elements do not have the relationship described, it means that there is a disconnect in the documentation, which undermines clarity. Finally, if a relationship is subject to change, it suggests a lack of stability or consistency, which is not conducive to being considered unambiguous. Thus, a characteristic of an unambiguous relationship is that it is clear and precise, allowing for accurate communication and understanding among all parties involved.
