89% of What Shapes Our Customers’ Experience is Invisible to Engagement Surveys
For three decades we have measured the wrong thing well. Here is what the new science lets us measure instead.
We have known for a long time that culture shapes customer experience. The Service-Profit Chain mapped the route in 1994: conditions inside an organisation shape how employees behave, how employees behave shapes what customers feel, and what customers feel shapes profit. The link was never in doubt. What we never had was a way to measure that link.
So, we measured the nearest thing we could, Employee Engagement. This was, for a long time, the best available proxy for customer outcomes. Employee Engagement is a serious field, rigorously researched, and there is a real correlation between an engaged workforce and a satisfied customer. The correlation is simply far weaker than we assumed. The most authoritative evidence in the field, Gallup’s meta-analysis, now in its eleventh iteration across 3.35 million employees and independently replicated by researchers with no commercial stake in the result, puts the true correlation at 0.33. Square it, as we must to find how much of one measure the other actually explains, and it comes to about 11%. Meaning, the best engagement instruments we have today can measure roughly 11% of what shapes our customers’ experience. In other words, somewhere in that remaining 89% lies the explanation of what impacts our customers, be that in positive or negative ways, and we cannot measure it.
A Comfortable Signal, and a Misleading One
Here is the uncomfortable truth we live with today: High employee engagement and poor customer outcomes can, and often do, exist side by side. A workforce can report that it is motivated, proud, and committed while the customers satisfaction slowly dwindles.
Worse, a strong engagement score is deceivingly reassuring. It tells a leadership team that all is well on the inside, and invites them to assume all is well on the outside too. Engagement measures how our people feel about their work. It does not measure what our customers experience, or are about to experience. Read as a proxy for customer health, it can lull an otherwise alert leadership team into a false sense of security at precisely the moment it should be taking corrective actions.
Engagement measures how our people feel about their work. It does not measure what our customers experience.
The Real Answers Sit Upstream
The conditions that decide a customer’s experience sit upstream, in signals that an engagement survey is not built to read. They are harder to see than sentiment, because they are not about mood. They are about the systems and behaviours inside our organisations that impact our culture and silently therefore our employee’s morale and overall engagement.
Consider a few. Whether a flawed decision gets challenged in the room, or not. Whether bad news is raised early, while it can still be fixed, or when it is too late, once it has already impacted a customer. Whether different teams answer the same question in different ways, potentially resulting in mixed signals to customers and markets, eroding trust. Whether the people who have carried your most valuable relationships for a decade still actually believe in where the company is heading, creating the risk of losing highly valuable employees. Whether these same employees’ authentic customer engagement begins to wane, turning an experience a customer remembers into one that they do not or worse, resulting in customer loyalty quietly being withdrawn.
None of these signals are captured by traditional engagement surveys and scores properly. All of them, however, reach the customer. The secret to reading them is timing. Catch the signal inside the organisation and act on it before it impacts the customer. This is a shift from managing customer outcomes after the fact, to managing the conditions that produce them, before the fact.

Total Employer Brand
We believe that an employer brand that is well constructed must be crafted to bring about good customer outcomes, not just good employee outcomes, and today most are not because this very hard or impossible to do. An employer brand is not complete unless also helps improve customer experiences, hence our labelling of ‘Total’ Employer Brand.
This diagnostic tool reads the upstream conditions that shape customer experience across six dimensions, each with two precisely crafted, science-based questions to measure a specific mechanism by which culture reaches, or fails to reach, a customer.
Psychological Safety measures whether people can raise problems without fear.
Internal Communication measures whether what the organisation says is clear, consistent, and believed.
Recognition measures whether effort and contribution are seen.
Value Alignment measures whether people’s own sense of what matters aligns with what the organisation stands for.
Leadership Style measures whether leaders build trust and fairness. How leaders treat their people is the template for how those people treat customers.
Brand Perception measures whether the experience inside the organisation matches the promise made outside it.
Read together, these six are not just a temperature check. They are a diagnosis based on rigours and new science. The diagnostic does more than show what is weak: it weights each condition by how strongly the evidence ties it to customer outcomes, so it tells us what to repair first. Of everything we could improve, which moves the customer most? The answer is no longer instinct. It is evidence-based.
Short By Design, Valuable When Repeated
The instrument is deliberately brief. Twelve questions across the six dimensions, two for each, plus a thirteenth that captures an Employee Net Promoter Score. Under five minutes to complete, and simple to put in front of a workforce. Brevity is not a compromise here, it is the point. A diagnostic this short means an organisation can run it multiple times without encountering survey fatigue, and will receive higher response rates. The real value is in the trend. Run once, it provides a strong initial diagnosis. Repeated over time, it distinguishes a passing dip from a genuine decline, and shows whether actions taken are working while there is still time to adjust.
A Report of Their Own, Seen by No One Else
Most diagnostic tools take something from the people who complete them and give nothing back. This one does the opposite, and for very good reasons.
Everyone who completes the diagnostic receives their own report. It carries their personal score across the same six dimensions, and for each one, offers practical guidance on how to improve that is grounded in the science: where they are flourishing, where they are struggling, and what the evidence suggests they can do about it. The report comes to them from SHAPE and Sedgwick Richardson. It is theirs alone, and never seen by their employer. The organisation receives results in aggregate, never any individual’s answers, only anonymised intelligence.
It is a key part of what makes the diagnostic so reliable. People answer honestly when their answers are private and worth giving, and honest answers are what make the organisational diagnosis accurate. The private report and the trustworthy measurement are the same act, seen from the employee’s and employer’s perspectives. And it is that trustworthy measurement which gives a leadership team the confidence to act on the conditions reaching its customers, before they are felt by them.
Privacy is not the cost of the measurement. It is the source of its honesty.
It is also, simply, the right thing to do. To hand every member of a workforce a private, science-based means of improving their own flourishing is an act of care. It is also employer brand in its truest form: the promise made outside an organisation, honoured inside it.
The Science It Stands On
The science beneath it is not ours to claim, and that is the source of its authority. The conditions Total Employer Brand measures are grounded in the science of human flourishing. Among the most advanced is the work of epidemiologist Tyler VanderWeele at Harvard University’s Human Flourishing Program. Flourishing science does what engagement never could. It measures the conditions under which people function at their fullest, each one separately and precisely, before collapsing them into a single number.
To build a diagnostic on that foundation, Sedgwick Richardson partnered with SHAPE, who work closely with academic and commercial institutions globally to put that flourishing science into practice inside organisations. Together we developed Total Employer Brand, as a proprietary diagnostic tool, one that measures the link between culture and customer impact with a precision the field has not had before, grounded in Harvard-aligned science.
And the science is not merely asserted, it has been validated at a scale that puts it beyond reasonable dispute. In April 2025, the Global Flourishing Study published its first findings in Nature Mental Health. It is the largest study of human well-being ever undertaken: 207,920 adults, in nationally representative samples across 22 countries, from the United States and the United Kingdom to Japan, Indonesia, and Nigeria, with further annual waves under way. It is a collaboration between Harvard, Baylor University, Gallup, and the Center for Open Science, pre-registered and openly published, so that independent researchers can verify the findings rather than take them on trust. What it established, for our purposes, is decisive: it is entirely possible to measure human behaviours and conditions consistently across radically different cultures. An instrument that holds its meaning in both Sweden and the Philippines can be trusted across a workforce spread over the same distances.
That is the foundation of our Total Employer Brand culture-customer impact diagnostic tool. For the first time, the cultural conditions that shape a customer’s experience, the ones engagement has always left invisible, can be measured, named, and ranked in the order that matters. Not after a customer has felt it, but before.
