System Engineering Management Plan
Section 4.9 - Model Text

4.9 Generation of specifications.

The system engineering process shall generate system and configuration item specifications in accordance with the requirements of MIL-STD-499, MIL-STD-970, and DEF STAN 05-28. This specification effort shall be compatible with the 'Configuration Management Plan' (CMP). Specifications shall be prepared in accordance with the requirements contained in the 'Documentation Standard' and the appropriate example model text.
These specifications shall as a minimum comprise:

• System/subsystem specification(s)
• HWCI development specifications
• CSCI software requirements specifications
• CSCI Interface requirements specifications
• CSCI product specifications
• HWCI product specifications
• TRDs and/or Product Acceptance Specifications
  

(Performance and Detailed Specifications i.a.w. MIL-STD-961D shall be produced when identified).

4.9.1 Specification maintenance.

• After initial release of a specification establishing any of the baselines or program plans, changes shall be controlled using the procedures detailed in the 'Configuration Management Plan'. Subsequent changes to each specification shall be formally approved using the change procedures defined in the 'Documentation Standard' and change shall be controlled by the CMP. These changes shall be documented and made a part of the specification (incorporated). Specifications and documentation entered into an internal developmental configuration shall be corrected or updated when necessary, by means of either a change or revision. The procedure for change and revision shall be detailed in the 'Documentation Standard' for the project.
  

4.9.1 Specification authentication.

• The cover page of the specification (or of each part of a configuration item specification) for a system/configuration item, i.e., as identified on the contract deliverable item list (CDRL) shall provide for an approval signature by a responsible person of the acquirer (customer). Authentication by the acquirer shall be accomplished on that issue of the specification which is the contractual requirement for the baseline which the particular specification defines. Changes to the specification subsequent to authentication by acquirer and its contractual incorporation shall be accomplished in accordance with the 'Configuration Management Plan'.
  

4.9.2 Specification release and approval.

• Each CI specification shall contain a release signature indicating that the document has been reviewed and is suitable for its intended use. In addition, each such specification shall be submitted to the acquirer for an approval signature. Approval by the acquirer will normally be accomplished on the issue of the specification submitted for a baseline. Completion of the release and approval activities indicates mutual acceptance by the acquirer and contractor.
  Revisions to these specifications shall require the same approval and authorization as the original document. Changes will always be via the methods and procedures defined in the 'Configuration Management Plan'.
