Reliability And Possibilities Of Improving Models Productivity At Different Organizational Levels

Working productivity is part of the group of relatively old, but still sufficiently reliable indicators of efficiency. Historically, more than a century ago, working productivity firstly began by monitoring at the level of a particular workplace, manufacturing unit and/or sector. Success of that time of this, so to say, microeconomic aspect of productivity measurement is the result of relatively simple production results, which were put in a relationship with a simple, mostly basic work. Meanwhile, the measurement of productivity at the level of the organizational units of enterprises and individual workplaces lost in importance, partly due to appearance of new, more complex measurement models for operational efficiency, but also due to a fall of input reliability (primarily working results of a certain unit) which were used in the productivity formula. Current aspects of measuring working productivity is generally associated to the level of the economy as a whole, individual industry and enterprise. This paper includes two key goals: a) to highlight problems and differences in the reliability of measuring productivity at different hierarchical levells and b) to suggest updated models of measuring productivity at the micro level, which, according to some specific author's experience, could compensate lower levels of reliability of working productivity model at the level of company's organizational units.
