- Systems Interface Matrix
A systems interface matrix also known as a systems interface diagram is a type of cause and effect matrix that shows each systems interface or connection between two or more systems that forms part of the approved design. A typical systems interface matrix is a table that includes rows showing each input (cause) and columns showing each (effect) or output.
A systems interface matrix is used to provide a framework for comparison when conducting a periodic functional test (end-to-end) of each systems interface.
Australian Standard AS1851 requires that a test 'end-to-end' of each systems interface be conducted (typically on a yearly basis) to ensure that each interface operates in accordance with the approved design.
