A business analyst (BA) assigned to a project has been asked to implement regulatory requirements...

 A satisfy relationship is a type of traceability relationship that indicates that a model element (such as a requirement, a design element, or a test case) fulfills the intent of another model element (such as a stakeholder need, a business requirement, or a regulatory requirement). By using a satisfy relationship, the BA can link the solution components that implement the regulatory requirements and show how they meet the compliance criteria. References:
