5. Characterize functions
Find the assessment criteria for each function (function fulfilled or constraints met).
Evaluate the level of the assessment criterion and its flexibility as accurately as possible.
Indicate the assessment limits.
Propose exchange rates (cost: appreciation level).
It is sometimes difficult to differentiate between functions and assessment criteria (especially when it comes to negation functions).
