If you’ve worked on any product in the past ten years, you’ve undoubtedly come across the Net Promoter Score (NPS).
On a scale from 1-10, "How likely is it that you would recommend our company/product/service to a friend or colleague?”
You sit back. You think, then you say “I’d definitely six your product to my friend or colleague.” Now, if you believe there’s something off about that sentence, you’re correct. No one in their right mind would respond that way. It does not make any sense.
Three main flaws are surrounding the current NPS metric. We’ll discuss their drawbacks and why Thought Merchants uses simple “yes or no” questions to conclude what NPS can’t accurately.
NPS is a customer loyalty metric or a management tool companies use to track, measure and determine how successful a product is over time, as well as how effective you are at delivering customer value. NPS group users into three archetypes:
Collectively, these archetypes generate an “NPS Score” between -100 and 100. The basic theory is derived from a correlation between NPS and organic growth to predict the future performance of a company. The higher the NPS score, the more likely you are to outperform your competitors.
NPS became popular when the “as a service” revolution hit. To compete, companies turned more customer-focused to meet the needs of buyers. Massive brands like Apple, Amazon, Siemens, American Express, and more, all use this metric to make “data-driven” decisions. With this data, they’re a better fit to predict consumer behavior, measure loyalty sentiment, and develop current business strategies.
The first problem with NPS lies in dilution and interruption. Because of its rapid popularity, managers of every size business churn out these surveys by any means necessary. Often NPS is asked alongside other hastily thought out questions, yielding less valuable results. From a design perspective, the surveys are messy. They propose a susceptible product experience question in the middle of the experience, interrupting the user flow.
How can we expect a proper response when we interrupt the experience with a modal question while dropping an array of ambiguous and thoughtless answer possibilities in front of them? NPS offers 11 answer choices for a simple “yes or no” question. According to the highly regarded Hick’s Law, this engrossing amount of options inhibits our decision-making process. From a human approach, we don’t describe our feelings and emotions through such arbitrary means.
Expecting accuracy through ambiguity is impossible. Most of the time, individual numbers on the 10-to-0 answer scale are not clearly labeled. When a user selects “7”, what do they honestly mean? This could be positive, neutral, or even negative when the scale is not accurately defined. How often in your daily life do you use a number to gauge your feelings? Rarely, if ever I hope.
This leaves the scale prone to sensitivity and information loss. We can’t argue against ten is greater than nine. NPS boils these down as equals, losing valuable information in the process. Responses 7 or 8 become null and void, reducing sample size and increasing the chances of statistical error. And 6-to-1 ratings all equal 0. Leaving marketers with various questions for such a simple question, would you recommend this product to your friend, or not?
Consumers are not looking for perfection; they’re looking for a business they can trust. NPS leaves too many open questions to when making an accurate, “data-driven” consumer strategy.
This is why the human approach is important when researching this type of consumer behavior. Using simple, real-life conversations is more approachable for consumers and gives you the answers you need. When you take away the arbitrary distractions, you can easily separate the two groups of people you are trying to find. Better yet, we don’t have to waste anyone’s time and money trying to arrive at these conclusions.
In the spirit of simplicity, Thought Merchants only runs NPS using yes and no as the answers to yield the one insight your company needs in this space.
Would you recommend this product to your friend? Yes…or no.

By thinking critically about the design that exists around us - evaluating what works, what doesn’t and why - we can apply new perspectives and rigor to our work designing applications and systems and communicate more effectively through design.
Our observations range from big corporate rebrands to local business street fliers. With each, we’ve taken the time to break down the designs and offer our point of view via a ranking system modeled after the Robert Parker wine rating system.
Unsatisfactory: Does not achieve design or communication goals.
Satisfactory: Just enough, sufficient, fine or “sure.”
Good: It’s good.
Very Good: Better than most but not exceptional.
Exceptional: Unusually good, rare, outstanding.
We love looking at new things, so if you want us to evaluate something you have seen or made, feel free to get in touch at firstname.lastname@example.org, and be sure to sign up for the quarterly Thought Merchants email to get new observations delivered right to you.
