In my field (pharma industry) efficacy is about a medicine that works in ideal controlled conditions (e.g. a clinical study) while effectiveness means that the medicine works in real world conditions, which are usual not controlled and far from ideal.

Efficient is a word that s root expresses a meaning but also, a type of slang. When the word is used it often has a double meaning. At least in some industries. Efficiency on the other hand is a more direct expression of value with ends facts to determine efficiency.
