Rec. 4: The DoD OIG recommended that the Commander of Anniston Army Depot conduct a review as required by DoD Instruction 4151.21, "Public-Private Partnerships for Product Support," of the direct sales public-private partnerships for the Joint Assault Bridge and the Stryker Family of Vehicles. During the review, the Commander should ensure Depot officials identify and document benefits of the partnerships, establish metrics to monitor the benefits, and implement a process to monitor the benefits. The Commander of Anniston Army Depot should also consider potential changes to the public-private partnerships during the review and implement those that maximize benefits for the Army.
