In the QET context, efficiency is understood as the relationship between a defined goal and the effort required to achieve this goal. Efficient behavior strives to achieve the defined goal with the least possible effort, ie with the "right" means (efficiency as an economic principle).
Doing things "right" (efficiency aspect) is contrasted with doing the "right things" (effectiveness aspect).
