What does a derive requirement relationship signify?

A derive requirement relationship signifies that a requirement at one end is logically derived from another requirement at a different end, indicating a dependent relationship. Choosing the interpretation that a requirement at the tail end is derived from the supplier end illustrates this concept effectively. In systems modeling and requirements management, this relationship usually denotes that the derived requirement captures or fulfills the broader or higher-level requirement defined by the supplier. Therefore, the derived requirement is specifically linked to the originating requirement, showing how one requirement is a more detailed or specific interpretation of the other.

Understanding this relationship is crucial in systems modeling, as it helps to clarify dependencies between requirements and ensures that all necessary conditions are met while tracing the lineage of requirements from a supplier to a client. This can assist in validation and verification processes, ensuring that derived requirements align with the original intent and scope established by the supplier.
