Specification Change Notice (SCN)

A Specification Change Notice (SCN) is used to record and transmit approved change pages to an existing paper specification. Once an Engineering Change Proposal (ECP) has been approved, the SCN provides official notice to holders of the specification that the attached change pages can be incorporated into their copy (ies) of the specification.

This Data Item Description (DID) contains the format, content, and preparation instructions for the data product resulting from the work task specified in the contract. This DID is used in conjunction with ECPs (DI-CMAN-80639C), and with NORs (DI-CMAN-80642C). A requirement for ECPs and NORs should be contractually imposed in conjunction with this DID.
