Why Strong CX Scores Don’t Always Translate into Growth

A financial institution can have strong NPS, satisfied customers, and still not be growing the relationships it needs to grow the balance sheet.
We’ve become very good at measuring customer experience. But I think executive leaders should expect more from that evidence than another measure of past performance.
The strategic question: Can that evidence help us see where customer relationships are changing while there is still time to influence what happens next?
Credit unions added 2.4 million members in 2025 and reached nearly 145 million, yet median credit union membership declined and roughly 55% ended the year with fewer members. Community banks grew deposits, but deposit growth alone doesn’t tell leadership whether customers are making the bank primary, expanding their relationships or becoming harder to displace.
Growth tells us what is happening. It doesn’t necessarily tell us why. Are customers bringing more of their financial lives to us? Are new relationships becoming primary and durable? Or would those customers just as readily choose someone else next time?
Financial results tell us where we ended up. Customer experience evidence should tell us where the relationship is changing while there is still time to do something about it.
Key insight: Strong CX scores describe performance. The evidence underneath them can reveal changes in relationship strength that an enterprise score or financial result may not show yet.
Need to Know:
- Strong CX scores don’t necessarily mean customer relationships are growing.
- The most consequential signals may be hidden beneath enterprise averages.
- Customer evidence has greater strategic value when it tells leadership where to look—and where there is still time to act.
- Consider what we’ve seen across three of our financial institution clients.
Case #1: Strong Scores Can Hide Early Relationship Risk
One of the country’s largest credit unions had numbers most executives would welcome: NPS approaching 80, Ease of Use at 4.69 and exceptionally strong service performance.
Those are good numbers. I wouldn’t argue otherwise.
But what do they actually tell us about whether the relationship is getting stronger?
Underneath those scores, members under 45 had lower advocacy than older members. Digital performance was particularly weak among some younger segments even while branch experiences were strong.
Then we looked at the early member relationship. Advocacy had declined materially by the 90-day point compared with the initial new-member experience.
Now we had a much better question: What is happening during the first months of the relationship, and can we see it early enough to respond?
Why it matters: A strong enterprise score can hide relationship deterioration in a strategically important segment or stage.
Case #2: One Digital Journey Can Actually Be Two Experiences
At another multi-state credit union pursuing a digital-first strategy, we started with a business question: Is digital easy and intuitive enough to support that strategy, and where is friction getting in the way?
Branch-supported new-account NPS was 73.98 versus 54.77 overall. Approved loans showed a similar difference: 80.87 versus 69.08. The analysis pointed toward the unassisted and virtual experience as a significant source of variation.
Now we had a much better question than, “How is digital account opening performing?”
What is human assistance solving that the unassisted experience isn’t?
The data shouldn’t be made to say more than it says. We don’t yet know whether the answer is verification, navigation, handoffs or something else. But we know where to look.
Key insight: Don’t ask only how a journey is performing. Ask what explains the variation within it.
Case #3: Satisfied Customers Don’t Necessarily Choose You First
A third institution showed clearly why satisfaction and relationship growth aren’t the same thing.
We asked members which financial institution they used most. Among those responding, 272 named another institution. Younger members frequently cited digital convenience, responsive human help, and speed and simplicity.
A customer can be satisfied with you. They can recommend you. And another financial institution can still own more of the relationship.
So I would ask: What separates the customers who like us from the customers who choose us first?
Growth implication: A customer who likes you isn’t necessarily a customer who chooses you first.
Start With the Business Question, Not the Survey
This is where I think we sometimes get customer experience backward. We start with the instrument: What questions should we ask? What benchmark should we use? Do we need another survey?
I would start somewhere else: What business question are we trying to answer?
If growth is slowing, what do we need to understand about newer customers? If digital adoption is lagging, where is friction and for whom? If satisfied customers aren’t deepening relationships, what distinguishes those who consider us primary from those who don’t?
What to do:
- Start with the consequential business question. Where are we trying to grow, retain or deepen a relationship?
- Find the customer evidence that can illuminate it. Look beyond the average for meaningful variation.
- Separate signal from conclusion. Be explicit about what the evidence tells you — and what it doesn’t.
- Determine what leadership can influence. Intelligence only has value if it improves a decision or action.
The survey is simply one way to gather that evidence. The decision we’re trying to improve is the point.
Don’t Wait Until After the Decision to Measure Its Impact
We are about to apply this thinking in a very different setting: a major credit union merger.
Financial institutions have precedent for measuring customer experience through major mergers and integrations. What appears less consistently documented in credit unions is a deliberate longitudinal approach — establishing a baseline before operational integration, listening systematically through the transition and measuring the same relationship indicators afterward.
We are beginning that work with one of the ten largest credit unions in the country. We don’t know what we’ll find. That’s precisely the point.
If trust changes, when does it begin? If ease deteriorates, where does friction appear? Do legacy groups experience the transition differently? What happens to advocacy and relationship intent?
Can leadership see those changes while there is still time to do something about them?
Key Insight: The objective isn’t to grade a major strategic decision afterward. It’s to give leadership intelligence while the customer relationship is changing.
Intelligence Only Matters If Execution Changes
There is one more piece I don’t want us to overlook. Even excellent intelligence doesn’t change performance. People do.
Employees execute the behaviors that strengthen relationships. Managers need to see where execution varies. Coaching must change behavior. Leadership decides which evidence deserves action.
I think about the progression this way: Measurement tells us what happened. Intelligence helps us understand why it matters. Execution determines whether anything changes. The financial result comes later.
Bottom line: We have spent years getting better at measuring customer experience. I don’t think the answer is simply more measurement.
The mandate is to use customer evidence differently: to reveal where the customer relationship is changing, why it matters to the business and where leadership still has time to act.
So, this is the question I would put in front of the executive team:
What can we see in the customer relationship today that we need to act on before it shows up in our financial results?
