This handbook has been prepared for Army Medical Department personnel involved in all aspects of materials acquisition. It describes the Medical Materiel Life Cycle System Management process and serves as an instruction manual for new personnel and as a road map for product development action officers to follow. The handbook reflects the latest acquisition initiatives, particularly as they relate to non-major systems. The handbook addresses, and is limited to, responsibilities of the materiel developer, combat developer, logistician, trainer and tester of medical materiel. The Surgeon General's responsibilities associated with the acquisition of non-medical materiel are not included. There are two volumes. Volume One provides an overview of the Army Life Cycle System Management Model, the participants in the medical materiel acquisition process, pre-milestone I activities, and a summary of medical programs -- development, nondevelopment, modified nondevelopment, and product improvement. Volume Two consists of eighteen acquisition process chapters (such as Integrated Logistics Support, Test and Evaluation, and Training) each with accompanying flow charts that show the sequence of events and document flow by time and agency/office responsibility. Narrative descriptions are provided to assist action officers involved in the specific process. The handbook also discusses the regulatory interfaces required for medical material development and production including biological and pharmaceutical product developments.
