Which of the following is part of a Property Control System?

A Property Control System is fundamentally focused on managing and safeguarding an organization's assets through systematic policies and procedures. The selection of policies, procedures, and operational guidelines is critical because they establish the framework that governs how properties are maintained, monitored, and controlled. This ensures consistent practices across various operational aspects, such as maintenance schedules, reporting protocols, and compliance with regulations.

The other options, while important in their own contexts, do not directly contribute to the core functioning of a Property Control System. Marketing strategies are aimed at promoting the property rather than managing it, vendor selection criteria pertain to the procurement process and not the internal management framework, and property design specifications are related to physical characteristics rather than control protocols. Therefore, the inclusion of policies, procedures, and operational guidelines is essential for effective property management and control.
