Who is responsible for building the MTL_MTP document?

The work center supervisor is responsible for building the MTL_MTP document because this individual is directly involved in managing the day-to-day operations of the work center. This role includes overseeing the personnel and resources necessary to meet the center's mission requirements. The supervisor has direct knowledge of the tasks, responsibilities, and training needed for their personnel, making them the most qualified to compile and create a document that accurately reflects the manpower, training, and equipment requirements for the work center.

In contrast, the other roles listed typically have different responsibilities. The training manager focuses on training programs and ensuring personnel meet qualification standards, the manpower division chief handles broader manpower management and allocation, and the personnel officer usually deals with personnel actions rather than the specific operational details of a work center. Therefore, the work center supervisor is the most appropriate choice for building the MTL_MTP document.
