System function breakdown structure - 3SE

Draft

https://www.3se.info/3se-onto/terms/system-function-breakdown-structure-3se-069c03f8a3ee7e9d

Breakdown structure of the system function that supports the system functional analysis by following the principles below:
(1) A system function is composed of at least two system element functions.
(2) A system function allocates a system activity.
(3) A system element function can be a system function.
