A Net Promoter Score (NPS) is a simple metric based on a question that asks how likely a person is to recommend a company to a friend or colleague using a numeric scale of 0-10, ten being extremely likely and zero being not at all likely.
Responses to this question are divided into three categories:
The NPS is then calculated by subtracting the percentage of Detractors from the percentage of Promoters.
Inavero’s Net Promoter survey also has NPS Driver questions including questions that allow for open-ended responses. The NPS Driver questions give firms the ability to diagnose potential causes of any problems. Additionally, the first open-ended question asks the reason for the numerical rating provided in response to the Net Promoter question, and the second asks what the firm could be doing differently to increase the value of their services.
The concept of the Net Promoter Survey was created by Fred Reichheld at Bain & Company and Satmetrix. The Net Promoter Score or NPS® was introduced by Fred in 2003 in his Harvard Business Review Article called “The One Number You Need to Grow”.
