Downloaded from https://www.everyspec.com MIL-STD-31000B APPENDIX A assignment reports will be described in the Contract. Cite DI- SESS-81011 in the CDRL and enter the tailoring in Block 16 of the CDRL. A.2.4.4 Proposed critical manufacturing process description. The proposed critical manufacturing process description is used to allow the procuring activity to approve or disapprove the documentation of a manufacturing process as critical in the TDP.
However, procuring activity personnel should take into consideration the adverse impacts of such approval processes on competitive procurement, contract costs and schedules, especially when such approval processes are extended throughout the subcontract chain. Requirement for the generation of proposed critical manufacturing process descriptions will be described in the Contract. Cite DI-SESS-81012 in the CDRL. Identify the procuring activity having critical manufacturing process approval authority and any tailoring in Block 16 of the CDRL. A.2.4.5 Engineering drawing tree. The engineering drawing tree is used to identify the structure of all documents in a TDP at a given point in time.
It is a top-down breakdown block diagram which is either broken down to the LRU level or down to the component or piece part level. Requirements for the engineering drawing tree will be in the Contract and TDP Option Selection Worksheet. Cite DI-DRPR-81961 in the CDRL and any tailoring in Block 16 of the CDRL. A.3 TDP OPTION SELECTION WORKSHEET GUIDANCE FOR FIGURE 5. The TDP Option Selection Worksheets should be used to identify selected options and tailoring requirements. Additional sheets may be attached to the form as necessary. The following paragraphs provide more detailed guidance on completing the TDP Option Selection Worksheet Figure 5. A.3.1. Headings.
Enter the System and Date Prepared. A.3.1.1 Contract No. Enter the number of the acquisition document shown in Block E, Contract/PR No., of the DD Form 1423. A.3.1.2 Exhibit/Attachment No. Enter the number or letter, which appears in Block B, Exhibit, of the DD Form 1423. A.3.1.3 CLIN. Enter the contract line item number from Block A, Contract Line Item No. (CLIN), of the DD Form 1423. A.3.1.4 CDRL data item No(s). Enter the data item number(s) from Block 1, Data Item No., of the DD Form 1423 entry for which the TDP Option Selection Worksheet being prepared. If the form applies to more than one CDRL data item, enter all applicable data item numbers.
A.3.2 Completing the TDP option selection worksheet. The following is required to complete the TDP Option Selection Worksheet. A.3.2.1 Block 1. TDP Level. Check the level of TDP required. The level selected should coincide with the requirements of the elements to be selected in Section 5 of the form. Add any remarks necessary for clarification. A.3.2.2 Block 2. Type and Format. The options in this block determine the TDP type and format(s). The first determination is the type TDP to be procured, 2D or 3D. This will be based on the type of items being procured, the complexity of the item(s), the capabilities of the contractors involved, and the government’s ability to use the data.
Determination on type and format should be made based on the government’s need for a particular type and format of TDP. In general, during the production phase of the lifecycle, 3D fully annotated models with derived 3Di viewables are preferred. During the conceptual development and prototype phase, minimally annotated 3D models alone may be sufficient. The TDP format will be clearly stated in the contract with an understanding of how lifecycle maintenance of the TDP will be performed. When specifying the TDP format, it is important to provide sufficient technical detail—for example, type of native CAD with version number (e.g. Creo 30
