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 1, of this standard. 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 or purchase order. 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 shall evaluate the cost of data items in relation to their value in the design, production, management, reprocurement, 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 shall tailor the requirements for each data product to ensure that only the minimum essential data necessary to meet the need is acquired. Tailoring decisions will take into consideration the commercial or military nature of the materiel being procured and its developmental status.
Procuring Activities shall carefully assess tailoring of data to ensure the necessary level of form, fit and function data is obtained. A.2.2. Selecting and ordering TDP levels . The determination as to the level of TDP shall 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 types . The determination as to the type of TDP (type 2D or type 3D) shall be made based on the nature of the item being procured. Three Dimensional (3D) based TDPs are preferred especially when the item is mechanical in nature. A.2.4 Selecting and ordering TDP elements.
When ordering TDP elements below, require the generation of a TDP containing the required elements in the Statement of Work. 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.2.4.1 Conceptual design drawings/models. Conceptual design drawings/models (DI-SESS- 81001D) 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 drawings/models should only be ordered under contracts containing concept exploration and research tasks. A.2.4.2 Developmental design drawings/models and associated lists. Developmental design drawing/models and associated lists (DI-SESS-81002D) 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 20
