Businesses strive to monetize the relationship between user sentiment and success outcomes including user adoption, user retention, and revenue. Customer satisfaction is embraced as a top predictor of success. There are of course many ways that satisfaction can be measured. We will review several methods of measuring user satisfaction, including simple Likert scale measures of overall satisfaction, the System Usability Scale (SUS), UMUX-Lite and the popular Net Promoter Scale (NPS). Not all of these measures are created equally or even measure the same sentiment. We’ll further compare the advantages and disadvantages of each measure, best practices around the use of each, and original research we’ve conducted that informs our recommended best practices.
