U.S. Dep't of Defense, Instruction No. 5025.01, Part II (Oct. 28, 2007)
DoDD. A DoD issuance that EXCLUSIVELY establishes policy, assigns responsibility, and delegates authority to the DoD Components. DoDDs shall not contain procedures. They shall consist of the following two types of issuances: (1) Direct Oversight DoDD: A DoD issuance, no more than 8 pages in length including enclosures, reserved for subjects requiring direct oversight by the Secretary or Deputy Secretary of Defense, approved and signed only by the Secretary or Deputy Secretary of Defense, and consisting only of one or more of the below types of information. (a) Non-delegable responsibilities assigned to the Secretary or Deputy Secretary of Defense. (b) Assignment of functions and resources between or among the Heads of the DoD Components and/or OSD Components. More specifically, this is when the fundamental responsibilities, functions, or authorities of the Head of the Component are being defined or redefined. These major assignments should not be confused with the collateral functions routinely mentioned in an issuance in which the Head of an OSD Component assigns a responsibility to (and coordinates with) the Head of another Component to perform a task within an assigned functional area. (c) EA assignments, which consist of the designation of an EA and the assignment of related responsibilities and authorities. (d) Matters of special interest to the Secretary or Deputy Secretary of Defense such as advisory boards or urgent Global War on Terrorism matters. They may be items selected by the Secretary or Deputy Secretary or recommended by the Head of an OSD Component. (2) Chartering DoDD: A DoDD that establishes the mission, responsibilities, functions, relationships, and delegated authorities of the Head of an OSD Component or other OSD PAS official, a Defense Agency, a DoD Field Activity, or other major DoD or OSD Component, as required. Also referred to as an “organizational charter” or “charter Directive.” Chartering DoDDs comprise a unique DoDD format, developed by O&MP in coordination with DD, and are exempt from the 8-page limit for DoDDs. Chartering DoDDs shall be signed by the Secretary or Deputy Secretary of Defense, except that where the Under Secretaries of Defense are delegated the authority in their chartering DoDDs, the Under Secretaries of Defense shall issue chartering DoDDs for their subordinate OSD PAS officials.
