Which relationship type suggests that one requirement can include another?

The relationship type that indicates one requirement can include another is Containment. This relationship is essential in modeling because it conveys a hierarchical structure where one requirement may encompass or be a composite of several other requirements. This allows for clearer organization and understanding of how more complex requirements can be broken down into simpler, constituent parts. By utilizing containment, analysts can effectively represent dependencies between requirements and ensure that all necessary components are considered as part of the overall requirement.

In contrast, derive requirement denotes a relationship where one requirement is inferred or derived from another, typically used to track the origin or transformation of requirements rather than highlighting inclusion. Satisfy relates to how a system or solution meets or fulfills a requirement, indicating compatibility rather than inclusion. Verify demonstrates the process of confirming that a requirement has been met by a system or component, focusing on compliance rather than the structural relationship between requirements. Understanding these distinctions is crucial for effective requirements management and system modeling.
