The American Customer Satisfaction Index
The ACSI® is the only national cross-industry measure of customer satisfaction that represents the U.S. economy.
As a proven predictor of financial performance, organizations from a wide range of diverse industries leverage the ACSI methodology to obtain science-based insights across the complete arc of the customer experience.
In competitive markets, firms are rewarded by treating their customers well and punished for treating them badly. The rewards/punishments show up, not only in earnings, but also in stock prices and make equity markets better aligned with consumer utility, which, in turn, causes an upward shift in demand curves. As a result, consumer spending increases and so does economic growth.”
