A functional architecture is a set of functions and their sub-functions that defines the transformations of input flows into output flows performed by the system to achieve its mission. (Created for SEBoK)


This definition was developed for the SEBoK.


The definition is adapted from ISO/IEC/IEEE 24748 - 4 (past IEEE 1220, ISO/IEC 26702) as functional architecture; but it is here modified to emphasize on transformations performed. See also definition of behavioral architecture .
