Even Bruce Temkin (Co-Founder of CXPA) and early NPS ambassador recently published an article describing the need to reinvent NPS. He called it “True Loyalty Measure”.
New tech vendors popping up and suggesting pNPS (predictive NPS) or eNPS (emotional NPS) – all pointing out other drawbacks of the NPS system. Against the background of this potpourri of small-scaled NPS facets, maybe it’s time to put it all together and develop something holistic and robust.
In this idea pitch, firstly, we will outline the current key challenges of the NPS. Secondly, we will illustrate a potential solution that leverages cutting but established 21st-century technology.
Besides all scientific and technological explanations, this idea pitch is intended as an invitation and inspiration to and for you as a corporate CX decision-maker. With you, we are willing to build the next phase of CX insights.

Benchmarking is a key exercise every C-Suite is asking for. At the very core, the management wants to know, “Is this a good score or is it a bad score?”
To answer this, customer insights teams sometimes struggle to find truly comparable benchmarks. Many companies invest in large NPS trackers that measure the NPS of all relevant competitors. Results still leave most experts puzzled. It often seems to be mysterious why, e.g., the market leader has such a high score.
Benchmarking even becomes impossible if you want to benchmark touchpoint/journey scores.
Research has shown that not only loyalty is impacting the NPS score but also brand strength and market share. We need an explanatory -not only a descriptive- answer to the question of “Is our performance good or bad?”
More and more NPS scores are used to incentivize the management of a company. This requires the score to be true and robust. In both aspects, the NPS system is easy to attack.
The NPS score is not true:
The likelihood to recommend is a rating scale that delivers responses that are highly biased by rational filters and methodological effects. Often loyal customers tend not to pick the 10 out of strategic rationale. Also, customers have a subconscious tendency to be polite and avoid picking 0-5 points on the scale.
Furthermore, only the endpoints of the scale are defined. As a result, you find major cultural differences in responding to the scale. The general concept of a 0 to 10 rating comes from the anglo-american region and is largely unknown in most other parts of the world. As such, people respond differently due to their traditions.
Other topics are biasing results: most customers you ask do not participate. What would have been their answer? Depending on the self-selection process, your results a chronically screwed. There are modeling methods for debias available, but they are hardly ever applied.
The NPS score is not robust:
The score calculates from the difference of percentage share values (% of promoters vs. % of detractors). As a well-known statistical phenomenon, small percentage scores have huge error bands for small sample sizes and, as such, are largely impaired compared to averaging Likert scales.
This impact is even amplified if you start to weigh your sample e.g., as you want to overweight your high-value customers. If, suddenly, one instead of two high-value customers are among your promoters, the NPS score changes dramatically.
Companies witnessing unexplainable differences between NPS scores. Large competitors often tend to have better scores, although some of them do not outperform your performance in any way.
The same you find when comparing NPS scores between countries or regions of the same brand.
Even worse with scores related to a touchpoint (or journey) survey. It’s hard to compare it with other touchpoints.
Part of the unexplainable differences can be explained by drivers or impact analysis. It helps to learn why the NPS is high are low.
But mostly, still, half of the variance stays unexplained. In other words: half of the differences in NPS is not due to CX performance but thru the specific market situation and brand strength.
Imagine there would be a solution that estimates a better NPS score. The score will be above 100 if the company performs better than a predictive model would expected based on the industry, touchpoint and market position. The predictive model is calculating the expected value of a look-alike company.
It would be below 100 if worse than such a look-a-like company or brand. The same applies to touchpoints or region cuts.
It would make benchmarking not only redundant. It would provide a much better answer of the question, “are we doing well”.
Imagine further that this new score is based on the neuroscientific measurement of implicit attitudes. (Actually, loyalty IS an implicit attitude). This method is intrinsically metric and not based on percentage values. As such, it has the foundation to be more reliable, robust, and true.
Imagine, finally, the score even controls many biases and also is able to retrieve more information from each customer (without the need for more time), which is used to stabilize the score.
Such a system provides for the first time a reliable benchmark for performance.
The worlds-largest marketing institute Ehrenberg-Bass conducted many large-scale studies (published in Byron Sharps’s famous book “How brands grow”). One key finding was that -independent from the category- larger brands have more loyal customers not because they are good but because they are large. Exactly this is what you find in CX studies around the world.
The very same finding is independently backed by the results of the iconic PIMS study finding thru modeling that market share is the key driver of profitability. This impact was found to be independent of any other business metrics. In other terms: market share drives customer loyalty and, thus, profitability. There are not just confounding other reasons (e.g. a better performance) that make market share appear to correlate with loyalty and profits.
From this perspective, benchmarking with competitors never made sense.
With the following new system, now, it will.
The following process has been planned out in order to solve all challenges above. We will build a survey, analysis, and data interfaces to make this system usable for everybody.
STEP 1 – REINVENTING the survey process
STEP 2 – REINVENTING the score with machine learning
STEP 3 – REINVENTING explaining why
STEP 4 – REINVENTING Deliverables
To implement this “Supra CX” concept in accordance with market needs, we need “you”. We can only work with one corporation (or a consortium) and develop and pilot the described system. All parts of the system are proven and tested. The task is not to develop the tech. The task is to tweak the setup and prove that it solves the issues outlined in this article.
