Every position that a security officer is assigned to has a set of post orders. Essentially a form of job description, post orders list everything that the officer is supposed to accomplish on his shift.
Post orders do more than just tell the guard what to do. They detail the policies of the enterprise that is being protected. The most effective sets will be joint creations, starting with what the client wants to be accomplished, incorporated in the manner the security professionals determine will be most effective, followed by a final review by the client.
Post orders are the groundwork for a security plan. They allow new officers to be familiarized with a position quickly, and ensure that the security officer is correctly implementing the protection measures that are specific to that location. Post orders for a position covering a hotel may contain detailed instructions on how to respond to guests or treat incoming packages, whereas an officer working at a parking lot may have guides on how to record vehicle information or remove a wrongly parked car, and these instructions would be of no value to the other position.
