Gartner Group suggests that over 50% of large US firms have adopted the BSC. More than half of major companies in the US, Europe and Asia are using balanced scorecard approaches, with use growing in those areas as well as in the Middle East and Africa. A recent global study by Bain & Co listed balanced scorecard fifth on its top ten most widely used management tools around the world, a list that includes closely-related strategic planning at number one. Balanced scorecard has also been selected by the editors of Harvard Business Review as one of the most influential business ideas of the past 75 years.
