The Interface Design Description (IDD) describes the interface characteristics of one or more items
which may typically be referred to as systems, subsystems, Hardware Configuration Items (HWCIs),
Computer Software Configuration Items (CSCIs), manual operations or other system components. An
IDD may describe one or more interfaces.
The IDD is used in system development to communicate and control external interface design, at the
most detailed level of definition of external interfaces, and consistent with requirements contained
within the companion Interface Requirements Specification (IRS) (see TAA-ME04-000936). The IRS
specifies interface requirements; the IDD describes interface characteristics selected to meet those
requirements. The IDD can also be used to supplement the System/Subsystem Design Description
(SSDD) (see TAA-ME04-001131), Software Design Description (SDD) (see TAA-ME04-001132), or
Database Design Description (DBDD) (see TAA-ME04-001134).
