Function (engineering)

According to the Gadomski 's observation (in the TOGA meta-theory) the term function in engineering and various systemic  contexts is usuallyReferencesused for the denomination of a goal-oriented necessary property of a system  or a process. In this sence, without a goal,  functions  do not  exist, therefore in physics the term function is used only in its mathematical sense. On the other hand, the same process can be the carrier of different functions, according to its aplication,  as well, the same function can be realized by different processes/systems (see the SPG  paradigm in TOGA).
