DoDI 4151.19 Serialized Item Management SIM for Life-Cycle Management of Materiel

In accordance with the authority in DoD Directive 5134.01 and pursuant to DoD Directive 4151.18 this instruction reissues DoD Instruction (DoDI) 4151.19 to update established policy and assigned responsibilities for implementing SIM in support of the life-cycle management of materiel. It is DoD policy to: a. Implement SIM to enable effective and efficient life-cycle management of materiel through the creation, capture, and use of life-cycle item management data (LCIM). LCIM data will: (1) Help achieve optimum materiel availability at the best total ownership cost. (2) Provide key performance parameters and key system attributes for weapons systems sustainment. (3) Be used to: (a) Improve the effectiveness and efficiency of DoD design, manufacturing, procurement, operations, maintenance, and logistics functions. (b) Improve weapon system readiness, reliability, and safety. This instruction promulgates policy on Serialized Item Management (SIM) which can help to achieve optimum materiel availability at the best total ownership cost, enable effective and efficient life-cycle management of materiel, and improve weapon system readiness, reliability, and safety.
