(a) Guidance on Life-Cycle Management.—The Secretary of Defense shall issue and maintain comprehensive guidance on life-cycle management and the development and implementation of product support strategies for major weapon systems. The guidance issued pursuant to this subsection shall—

(1) maximize competition and make the best possible use of available Department of Defense and industry resources at the system, subsystem, and component levels; and

(2) maximize value to the Department of Defense by providing the best possible product support outcomes at the lowest operations and support cost.

(b) Product Support Managers.—

(1) Requirement.—The Secretary of Defense shall require that each major weapon system be supported by a product support manager in accordance with this subsection.

(2) Responsibilities.—A product support manager for a major weapon system shall—

(A) develop and implement a comprehensive product support strategy for the weapon system;

(B) use appropriate predictive analysis and modeling tools that can improve material availability and reliability, increase operational availability rates, and reduce operation and sustainment costs;

(C) conduct appropriate cost analyses to validate the product support strategy, including cost-benefit analyses as outlined in Office of Management and Budget Circular A–94;

(D) ensure achievement of desired product support outcomes through development and implementation of appropriate product support arrangements;

(E) adjust performance requirements and resource allocations across product support integrators and product support providers as necessary to optimize implementation of the product support strategy;

(F) periodically review product support arrangements between the product support integrators and product support providers to ensure the arrangements are consistent with the overall product support strategy;

(G) prior to each change in the product support strategy or every five years, whichever occurs first, revalidate any business-case analysis performed in support of the product support strategy;

(H) ensure that the product support strategy maximizes small business participation at the appropriate tiers; and

(I) ensure that product support arrangements for the weapon system describe how such arrangements will ensure efficient procurement, management, and allocation of Government-owned parts inventories in order to prevent unnecessary procurements of such parts.
