About this file
This document is a Data Item Description (DID) for an Engineering Change Proposal (ECP) with the identifier DI-SESS-80639E, approved on February 11, 2020. The DID provides the format, content, and usage guidelines for documenting engineering changes, specifically using DD Form 1692. It outlines three acceptable formats for the ECP: the standard DD Form 1692, the Acquirer's Integrated Digital Environment (IDE) schema, or the Supplier's preferred format. The document references EIA-649-1 standards and indicates that the ECP should comprehensively describe an engineering change and specify its implementation method. This version supersedes the previous DI-SESS-80639D and may be used in conjunction with a Notice of Revision (NOR) document.
