The ACSI Approach: A Methodological Primer

The American Customer Satisfaction Index (ACSI) has a proven relationship with customer spending, shareholder value, cash flows, business performance and GDP growth. The technology upon which it is based is backed by over 70 years of rigorous scientific inquiry in the fields of consumer psychology and psychometrics, coupled with advanced analytic techniques from statistics, econometrics, and chemometrics. While applicability of the ACSI technology to the management of commercial product and service companies has been repeatedly demonstrated in the literature, this paper provides a basic description of the underlying analytic technology.

The purpose of this paper is to provide the reader with an overview of how the ACSI technology, as delivered by CFI Group, meets the performance measurement requirements of the business community and improves the management and delivery of products and services to customers. This is accomplished by:

  • Describing the rigorous methodology used by CFI Group to harness the power of the ACSI technology. This section focuses on highlighting the critical elements of the methodology that provides highly accurate measurement coupled with sensitive diagnostic and powerful prognostic capability.
  • Summarizing the major components of the technology as implemented by CFI Group and the benefits realized by managers.
  • Comparing the ACSI technology base with some of the more common alternative methodologies offered by competing firms.
  • Reviewing the results achieved by CFI Group clients with a brief compendium of case studies illustrating many of the points made throughout the paper.
  • Providing technical appendices with in-depth discussions of various aspects of the ACSI technology as implemented by CFI Group.
  • Documenting the scientific nature of the ACSI technology by numerous references to secondary literature throughout the paper and in the bibliography.
