Downloaded from https://www.everyspec.com MIL-STD-31000B APPENDIX A SELECTION AND ORDERING GUIDANCE A.1 SCOPE. A.1.1 Scope. This Appendix provides guidance for procuring activity personnel on the acquisition of the various types of technical data and the completion of the TDP Option Selection Worksheet, Figure 5. This appendix is not a mandatory part of this standard; however, the TDP Option Selection worksheet is mandatory if it forms part of a contract. A.2 REQUIREMENTS. A.2.1 General. Procuring activities acquiring technical data are required to carefully review their respective needs for technical data and TDP data management products. A.2.1.1 Tailoring.
Procuring activities will evaluate the cost of data items in relation to their value in the design, production, management, re-procurement, maintenance, logistics support and use of the product. (The DD Form 1423, Block 18, Estimated Total Price, is the means to establish the cost of each data item.) In addition, activities acquiring data will tailor the requirements for each data product to ensure that the essential data necessary to meet the acquisition programs’ long term needs is acquired. Tailoring decisions will take into consideration the commercial or military nature of the materiel being procured and its developmental status.
Procuring activities should carefully assess tailoring of data to ensure the necessary level of form, fit and function or detail data is obtained to maximize availability of competitive acquisition and product support alternatives. A.2.2. Selecting and ordering TDP levels. The determination as to the level of TDP should be made based on the nature of the item being procured, the lifecycle phase of the product, and the level of data required by the procuring activity. A.2.3 Selecting and ordering TDP elements. When ordering TDP elements and associated data below, require the generation of a TDP containing the required elements and associated data in the contract.
Cite the appropriate DID and reference a TDP Option Selection Work Sheet in the CDRL. Complete a TDP Option Selection Work Sheet (including tailoring) and include it in the solicitation, contract or purchase order. A.2.3.1 Conceptual design data. Conceptual design data (DI-SESS-81001) are used when there is a need to verify preliminary design and engineering and confirm that the technology is feasible and that the design concept has the potential to be useful in meeting a specific requirement. Conceptual design data should only be ordered under contracts containing concept exploration and research tasks. A.2.3.2 Developmental design data and associated lists.
Developmental design data and associated lists (DI- SESS-81002) are used to describe a specific design approach. They provide the information to produce materiel for test or experimentation, and for the analytical evaluation of the inherent ability of the design approach to attain the required performance. Developmental design data should only be ordered under contracts when a limited set of data is sufficient for the intended purpose. A.2.3.3 Product design data and associated lists.
Product design data and associated lists (DI-SESS-81000 or DI-CMAN-80776) should be selected when there is a current or future need for the Government to procure or manufacture the equipment, components, or spares and repair parts from either the original manufacturer or an alternate source, or for other reasons in which a complete design description is needed in support of the item. When product design data are ordered for large, complex items such as major weapons systems, tailoring decisions should include consideration of ordering commercial design data for selected commercial items used as subassemblies.
It should also be noted that where there are fully justified DoD peculiar documentation practice requirements, such as the DoD system for Numbering, Coding and Identification, ASME Y14.100 and applicable appendices should be invoked . The use of the appendices to ASME Y14.100 will usually be associated with 27
