(2)  Promote cooperative research, development, investment, and application of VV&A
technologies.


(3)  Establish standards for implementing VV&A for DoD models, simulations, and their associated data to promote DoD VV&A procedural commonality and foster model and simulation interoperability.  Established standards shall be reviewed periodically to ensure currency.

2.  DIRECTOR OF OPERATIONAL TEST AND EVALUATION (DOT&E).  The DOT&E
shall prescribe policies and procedures, and provide guidance on VV&A for DoD models, simulations, and their associated data used for operational test and evaluation and live fire test and evaluation.

3.  HEADS OF THE DoD COMPONENTS AND OSD PAS OFFICIALS.  The Heads of the DoD Components and the OSD PAS Officials shall:
a.  Develop guidance for VV&A practices for models, simulations, and associated data, within their areas of responsibility.

b.  Document the results of VV&A for models, simulations, and associated data.  Make VV&A documentation accessible to other DoD Components as applicable and in accordance with Reference (d).

c.  Serve as the final validation authority for representations of the DoD Component's forces and capabilities in common and general use models, simulations, and associated data, within their areas of responsibility.

d.  Resolve validation issues for representations of the DoD Component's forces and capabilities as requested.

e.  Be responsive to other DoD Components to ensure the DoD Component's forces and capabilities are appropriately represented as requested.

f.  When designated as a functional Executive Agent or M&S Coordination Agent, operating as approved by AT&L and with advice from the M&S Steering Committee:


(1)  Upon request, provide domain information and expertise in support of VV&A
activities.


(2)  Ensure that data quality information is available and accessible to support the other DoD Component's VV&A activities.

g.  Assign responsibilities to ensure that:

(1)  Models, simulations, and their associated data that are developed or modified on behalf of the DoD Component are verified and validated throughout their lifecycle.


(2)  Models, simulations, and their associated data that are used by the DoD Component are accredited for the intended use.


(3)  VV&A resources are provided by the Component developing, modifying, or using the models, simulations, and the associated M&S data.

4.  DIRECTOR, DEFENSE INTELLIGENCE AGENCY (DIA).  The Director, DIA, under the authority, direction, and control of the Under Secretary of Defense for Intelligence, shall:
a.  For representations of non-U.S. forces and capabilities:

(1)  Serve as the final validation authority.



(2)  Be responsive to DoD Components to ensure that U.S. national and joint intelligence processes are appropriately represented.

## Enclosure 2 Documentation Procedures

 1.  This enclosure defines the minimum set of items to document as part of VV&A.

a.  Common Documentation Requirements

(1)  Identification of the date performed and the person or organization performing the verification, validation, or accreditation activities.


(2)  Identification of the version and/or release of the model, simulation, or associated data being verified, validated, or accredited.


(3)  Identification of the intended use of the model, simulation, or associated data being verified, validated, or accredited.


(4)  List of or reference to the M&S requirements and associated accreditation criteria for the model, simulation, or associated data being verified, validated, or accredited.


(5)  List of, and description of, the verification and/or validation and/or accreditation assessment activities.

b.  Additional Documentation Requirements for V&V.  Summary of results, including the M&S limitations risks, potential impacts, and assumptions of the models, simulations and/or the associated data undergoing V&V.

c.  Additional Documentation Requirements for Accreditation Activities
