Which of the following is NOT a procedure established by the DMLSS system?

The correct answer is the option relating to "Timeline," as it is not a specific procedure established by the Defense Medical Logistics Standard Support (DMLSS) system.

DMLSS is designed to enhance the medical logistics capabilities of the Air Force by streamlining order processing, inventory management, and supply chain tracking. Each of these established procedures plays a crucial role in ensuring efficient management of medical supplies and equipment within military treatment facilities.

Order processing involves the steps required to procure and manage orders efficiently, while inventory management focuses on the oversight of stock levels, ensuring that the necessary medical supplies are available when needed. Supply chain tracking is critical for monitoring the flow of supplies from order placement to delivery, ensuring accountability and traceability of resources.

In contrast, "Timeline" does not define a procedure within the DMLSS structure, as it lacks the specificity related to operational functions that the other options possess. This understanding of how DMLSS operates is essential for those involved in medical logistics within the Air Force.
