Key performance indicators (KPIs) are critical for understanding the performance and health of a business. Measuring the right KPIs helps customer experience (CX) leaders adjust their strategies to deliver superior experiences that ultimately link to overall organizational goals. Forrester’s Customer Experience Index (CX Index™) is a useful KPI for CX leaders because it measures how the quality of customer experience drives customer loyalty. Brands that appear in one of our benchmark studies can compare themselves not only to direct competitors but also to disruptors in other industries. This report compiles our recent research on the CX Index to help CX leaders understand its value and application.
