Technical Product Definition Information. In this activity we review the supplied technical data package (TDP) at a Level 3 Production per MIL-STD-31000 definition. We will make additions to the TDP if information is missing or outdated. A TDP is a technical description of an item adequate for supporting an acquisition strategy, development, manufacturing development, production, engineering, and logistics throughout the item's lifecycle. The technical description defines the required design configuration and procedures required to ensure adequacy of item performance. A TDP is comprised of a variety of data that will define the item. A level 3 production TDP consists of those elements necessary to provide the design engineering, manufacturing, inspection, packaging and quality management system provisions necessary to enable the procurement or manufacture of an item. The product shall be defined to the extent necessary for a competent manufacturer to produce an item, which duplicates the physical, interface, and functional characteristics of the original product, without additional design engineering effort or recourse to the current design activity. Production data shall reflect the approved, tested, and accepted configuration of the defined delivered item. Brighton Cromwell Technical Center (BCTC) engineering drawings are developed to ASME Y14.100 and ISO 9001:2015 QMS.
