Net Promoter Score® (NPS) is a trademarked metric between -100 and 100 that measures the likelihood of a company’s customers to to promote the brand through new customer references or/and repeat business.
NPS also stands for the Net Promoter System®, a trademarked system and framework that was built around the Net Promoter Score, It is a model that essentially tries to tie a corporation’s bottom line with its customers’ happiness and satisfaction with the company’s products and services. This system aims at managing corporate profits and sustainability through a customer experience lens.
When Was the Net Promoter Score Developed?
The Net Promoter Score® is a framework created by Bain & Co consultants in early 2000, and more specifically by Fred Reichheld, a partner at the firm who was leading the customer loyalty practice at the time. This Net Promoter Score concept came about after obtaining decades of field experience in customer market research, advising senior executives of Global 2000 companies on topics of customer loyalty and growth, and publishing a decent amount of literature on the subject. Harvard Business School Press published his first book on the Loyalty Effect in 1996, followed by his book Loyalty Rules in 2001.

Realizing the limitations of the traditional approach to customer surveys – highly complex, lengthy, labor-intensive (cross-departmental inputs), and the low response rates leading to modest or unreliable insights – Fred Reichheld and his team of consultants embarked on a quest to downsize the customer survey. This quest entailed finding a single question that would unearth a similar amount of insights as its lengthy and unwieldy customer survey counterpart and whose answer would somewhat be predictive of a company’s revenue growth.
The research project culminated in the paper The One Number You Need to Grow published in the Harvard Business School review in 2003. It summarized the findings and revealed the now extremely popular survey question “How likely is it that you would recommend our company/product/service to a friend or colleague?” and its associated Net Promoter Score.
The success of the paper, and the rapid adoption of the Net Promoter Score across organizations globally, encouraged the team to further develop the metric into a broader management model. Fred Reichheld and his disciple Rob Markey published subsequently two books: The Ultimate Question: Driving Profits and True Growth, in 2006 and The Ultimate Question 2.0: How Net Promoter Companies Thrive in a Customer-Driven World in 2011.
