Productivity is defined as the relationship between the output generated by a production or service system and the input provided to create that output. Management contributes the most to annual productivity increases at around 4/6, while capital and labor each contribute around 1/6. Productivity measurement is important for improvement, decision-making, and evaluating development programs. There are multiple approaches to measuring productivity at different economic levels. Effective productivity measurement addresses objectives, efficiency, effectiveness potential, comparability, and trends.
