Thanks to Christopher A. Seaman, I. Elaine Allen and Julia E. Seaman for an excellent critique of the net promoter score (NPS) in “Statistics Spotlight: The Complete Picture” (February 2019, pp. 52-56). Another shortcoming of the NPS not mentioned in the article is that certain clients won’t answer the NPS question “willingness to recommend” because they don’t want to be seen as promoting one organization over another. This can distort the reporting of NPS results. But those clients are willing to answer the customer satisfaction question. Unfortunately, too many organizations are fixated on the NPS.
