1. Preparing the group for organic function classification

A function is characterized by an action, a reaction and a negation.

The aim of the group work is to understand all the implications of the interactions between the different external environments (ME), and to express the functions in three different forms.

This working method enables :

• check the work already done by going into even more detail;

• find missing or poorly expressed functions ;

• specify functions ;

• highlight the parameters to be measured to guarantee functions.
