EuroCoach is a holiday coach company that Is reviewing its internal business processes. The following requirement for improvement has been logged as…

The business rule originates from an external source—a legal or regulatory authority—not from within EuroCoach. This rule imposes a mandatory limitation on the company's operations, compelling them to verify passenger documentation. It is not a guideline or an internal choice; it is a restriction that must be obeyed. Therefore, it is classified as an external constraint, as it is a rule imposed from outside the organization that limits its freedom of action and dictates how a part of its business must be conducted.

A. Internal policy: This is incorrect because the rule is mandated by law, an external source, not created by the company's own management.
B. Internal process: This is incorrect because the rule is a directive that will necessitate a change to an internal process, but it is not the process itself.
C. External requirement: While the rule comes from an external source, 'constraint' is more precise. A legal obligation is a non-negotiable boundary, which is best defined as a constraint.
