The document summarizes Intuit's journey in developing better metrics to measure customer satisfaction and loyalty through the Net Promoter Score (NPS). It discusses how Intuit shifted from using vague satisfaction statistics to the NPS, which asks customers how likely they are to recommend the company. This led Intuit to gain insights into detractors versus promoters. While the NPS helped Intuit improve customer experience and growth, some critics argue it is not the single best metric and other measures may provide better predictions of customer behaviors.
