What document is required to specify an agreement or procedure between two positions within a facility?

The correct choice is the Standard Operating Procedure (SOP). An SOP is an essential document that outlines specific procedures and guidelines for operations within a facility. It serves to ensure consistency and quality in processes, helping staff understand their roles, responsibilities, and the steps involved in carrying out tasks effectively.

By providing detailed instructions, an SOP helps facilitate smooth operations between different positions, ensuring that there is a clear understanding of procedures that all personnel should follow. This is particularly important in environments like air traffic control, where precision and adherence to established processes are critical for safety and efficiency.

While other documents like a Letter of Agreement may outline agreements between different entities or agencies, or an Operational Coordination Document might detail how agencies work together, the SOP specifically focuses on internal procedures and operational standards within an organization. The Facility Management Plan typically addresses broader administrative and operational strategies rather than specific procedural instructions.
