The aim of this article is to present terminological concerns connected with work efficiency as well as to attempt to define the issue. It is intended to serve as a clarification in the discussion on the practical aspects of work efficiency, including work outcome measurement and high work efficiency systems. Three issues are of prime importance in discussions on work efficiency: What are work outcomes and inputs? How can work efficiency be defined and evaluated? What factors influence the level of work efficiency? Another important question is how to include the social aspects of work efficiency and their consequences on assessing it.
