Perfection of classification of efficiency on the basis of system approach

The article considers the concept of classification of efficiency, conducts a critical analysis of existing classification features and reveals the most common shortages in the process of dividing efficiency into types. It proves that efficiency, as a category with polymorphic nature, requires to be studied on the basis of a system approach. This is used as a basis of perfection of classification of efficiency, which takes into account scales of activity of the system and elements of assessment. The article identifies main classification features of division of efficiency: the sphere of public life, type of activity, functional direction of activity, organisation structure, nature of effect, comparison base and the moment of carrying out calculation.
