What are interfaces in system engineering?
Interfaces provide the specifications of the relevant properties of a system or component that can be connected to other systems or components while instances of interaction are identified in order to specify the actual integration to other systems or components..
What is an ICD in engineering?
The Interface Control Document (ICD) created using this template will define one or more interfaces between two systems.
Overall, an ICD can cover requirements for any number of interfaces to a system.
Note: If there are multiple interfaces, they can be listed in a single ICD or multiple ICDs as needed..

What is in an interface control document?
For each interface, the ICD provides the following information: A description of the data exchange format and protocol for exchange.
A general description of the interface.
Assumptions where appropriate.
Estimated size and frequency of data exchange..
What is the interface control document process?
The interface control document is one of the components of the Design Document.
It is used to describe the inputs and outputs of a single system, the interface between two systems or the interface protocol between physical components..
- The ICD can describe the input or output interface of a single system only, or the interface of two systems or subsystems or components.
In some instances, a different document called the interface definition document (IDD) is used to describe the unilateral interface from one system only. - 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 PPA-002234).
- The purpose of the ICD is to clearly communicate all possible inputs and outputs from a system for all potential actions whether they are internal to the system or transparent to system users.
