Which concept helps to verify that all relationships among requirements are complete?

The concept that helps to verify that all relationships among requirements are complete is Business Analysis Information Architecture. This framework is crucial for organizing and structuring the requirements and their relationships, allowing business analysts and stakeholders to visualize how each requirement interacts with others.

Business Analysis Information Architecture provides a systematic way to document the various requirements, categorize them, and establish connections among them. By doing so, it ensures that no requirement is overlooked, and the relationships between them—such as dependencies, hierarchies, and interactions—are thoroughly mapped out. This verification process is essential for maintaining clarity and coherence within the project, helping to avoid gaps or conflicts in the requirements that can arise if the relationships are not fully understood or documented.

In contrast, requirements evaluation primarily focuses on assess quality and feasibility, while scope management deals with defining and controlling what is included in the project. Risk management involves identifying potential project risks and their impacts, which does not directly pertain to confirming the completeness of relationships among requirements. Therefore, the Business Analysis Information Architecture is the most appropriate choice for verifying the completeness of relationships across requirements.
