It is in this area that the unique skills of the professional assets protection manager can be effectively utilized. Rather than wait for the losses to occur, management should actively work to create a climate in which every employee accepts personal responsibility for the integrity of the work area. Supervisors should be instructed to report every instance of a mysterious disappearance to the assets protection organization, and higher levels of supervision should not approve the purchase of replacement equipment or tools unless they have been assured that the supervisor has formally reported the loss. Security, like safety, should become a performance measure of the supervisor. Just as the safety engineer provides safety support, so should the professional assets protection manager provide security support. But the ultimate responsibility for the internal security in a department must rest with the line supervisor. Whenever such a direct line of accountability exists, many of the so-called “mysterious disappearance” losses suddenly cease.
