Companies invest billions annually in customer, brand, and employee experience initiatives yet treat them as fundamentally separate domains with different owners, budgets, and measures of success. The result is a blind spot: No cross-company dataset has existed to show how employee experience factors link to customer satisfaction and brand experience outcomes, leaving leaders unable to make a credible business case for investing in linking them. Forrester’s Employee Experience Index (EX Index™) research brings just this capacity to Forrester’s total experience methodology; the findings enhance our understanding of what it takes to deliver sustainable customer and brand excellence.
