We were mapping the mortgage application journey when a branch manager, reviewing the customer touchpoint diagram on the wall, went quiet. "This looks exhausting," she said. "And we do this to ourselves every single day."
She wasn't talking about the customers anymore. She was talking about her team.
That moment – when the conversation shifts from fixing the service to understanding ourselves—happens in almost every service design project. And it's often where the real work begins. Because service design, when done properly, functions as something more than a process optimisation exercise. It becomes a mirror that reflects back the culture sitting at the heart of your organization: the habits, behaviours, attitudes, and belief systems that shape how your people work.
Most organisations have a reasonably clear idea of their culture. It's articulated in values statements, discussed in leadership meetings, and reinforced in onboarding programs. We're collaborative. We're customer-centric. We're innovative. We empower our people. Then you start mapping a customer journey, and a different story emerges.
You discover that the "collaborative" organization actually has three departments who each maintain their own customer database because nobody trusts the others' data quality. The "customer-centric" company has designed a returns process that requires customers to call twice, email once, and wait for a manager's approval, because that's what protects the business from fraud. The "innovative" culture turns out to have seventeen approval gates for any change to a customer-facing process, each one added after someone, somewhere, made a mistake that got escalated.
These aren't contradictions. They're the reality of how culture actually works. Culture isn't what we say we value, it's what we do when we're not thinking about it. It's the accumulated habits and micro-decisions that compound over time into the experience we deliver. and service design, with its relentless focus on how things actually happen rather than how we think they happen, makes those patterns visible.
Service design is particularly effective at surfacing culture because it starts with outcomes rather than intentions. When you map what actually happens when a customer tries to change their address, or book an appointment, or resolve a complaint, you can't help but see the organisational reality that produced that experience.
Consider the healthcare provider whose patient journey mapping revealed a curious pattern: patients consistently rated their in-person consultations highly, but their overall experience poorly. The problem wasn't clinical, it was cultural. Between departments, nobody owned the transition. Booking systems didn't talk to each other. Test results went to the wrong place. Patients had to repeat their information five times because five different teams needed it in five different formats.
Each individual touchpoint was optimised. But the culture was fundamentally siloed, with each department protecting its own processes and systems. The service design work didn't just reveal inefficiency, it revealed a belief system where departmental autonomy trumped patient experience. Where "that's not our responsibility" was an acceptable response. Where the definition of "doing a good job" stopped at the boundary of your own team.
That's information an employee engagement survey won't give you. It's insight that the org chart won't reveal. But it's written into every step of the service you deliver.
There's a principle in service design that customer pain points often mirror employee pain points. When customers struggle, it's usually because employees are struggling first.
The confused customer journey? That's probably a confused employee journey underneath. The frustrating handoff? There's likely a frustrating internal handoff that precedes it. The process that feels bureaucratic and slow? Someone on your team is probably drowning in that bureaucracy every single day.
One financial services company discovered this when examining why their online application process had such a high abandonment rate. The service design research revealed that customers were dropping out because they weren't sure what documents they needed, or whether their application was progressing. But when the team mapped the employee experience, they found something more fundamental: the back-office staff processing applications didn't know either. The status of any given application lived in someone's head, or in an email thread, or in a note on a physical file. There was no system of record. No shared understanding.
The employees had developed elaborate workarounds and tribal knowledge to cope. They'd created their own shadow systems, their own ways of tracking things, their own informal rules about what took priority. They were working heroically to deliver despite the infrastructure, not because of it.
The cultural revelation wasn't that the process was broken. It was that the organization had normalised this level of chaos. That "just figure it out" was accepted management guidance. That asking for better tools or clearer processes was seen as complaining rather than problem-solving. The service design work made visible a culture where adaptation to dysfunction was more valued than fixing dysfunction.
Perhaps the most profound cultural insights from service design come when you start asking why. Why does this handoff happen this way? Why do we require three signatures for this decision? Why don't these teams talk to each other?
The answers reveal belief systems.
"We've always done it this way" reveals a culture where precedent outweighs evidence. "Legal won't let us" often reveals a culture of risk aversion where the default answer is no. "That's not our department" reveals a culture where boundaries matter more than outcomes. "We tried that once and it didn't work" reveals a culture where failure isn't a learning opportunity, it's a reason to never try again.
These beliefs compound. They shape hiring decisions, shape who gets promoted, shape what ideas get funded and which ones get quietly shelved. They become self-reinforcing. And they're virtually invisible until you start examining the service experience they produce.
A manufacturing company discovered this when redesigning their order fulfillment process. The customer experience was slow and unpredictable, but the root cause wasn't capacity or technology, it was a deeply held belief that customisation was dangerous. Years earlier, a custom order had gone badly wrong, costing the company a major client. The response had been to make customisation increasingly difficult: more approval steps, more documentation, more checks. The message was clear: we don't trust our people to handle anything non-standard.
Twenty years later, that one incident had calcified into organisational dogma. The service design work made visible how much energy was being spent protecting against a past mistake, and how much opportunity was being lost in the process.
Discovering that your service challenges are actually cultural challenges can be confronting. It means that fixing the service isn't just about redesigning touchpoints or implementing new technology. It means addressing the deeper patterns of how your organization works.
But this is also where the opportunity lies.
Service design projects fail when organisations treat the findings as a list of process improvements to implement. They succeed when organisations recognise that sustainable service transformation requires cultural evolution. That means confronting the habits that don't serve you anymore. Examining the belief systems that made sense in a different context but are now holding you back. Building new muscle memory around how work gets done.
The retail bank with the exhausted branch manager? They didn't just redesign their mortgage process. They used the service design insights as a catalyst for a broader conversation about autonomy, decision-making, and trust. They reduced approval gates. They invested in training that built confidence rather than just compliance. They changed how they measured success to include employee experience alongside customer outcomes.
The transformation took longer than a simple process redesign would have. But it was more durable, because it addressed the cultural foundations that would otherwise have undermined any surface-level changes.
The most successful service design initiatives are the ones where leadership enters the work understanding that they're not just going to get a roadmap for improving services. They're going to get a diagnostic of their organisational culture. And they're prepared to act on what that diagnostic reveals.
This requires a particular kind of courage. It means being willing to hear that your culture might not be what you thought it was. That your values and your behaviours might not align. That the problems your customers experience might be symptoms of deeper patterns you've been avoiding.
But it also requires optimism. Because if your service challenges are cultural challenges, that means they're within your power to address. You don't need to wait for market conditions to change or for new technology to become available. You can start by examining your own habits, your own beliefs, your own ways of working.
Service design holds up a mirror. What you do with what you see, well, that's where leadership happens.
The question isn't whether your next service design project will reveal your culture. It will. The question is whether you're ready to look clearly at what it shows you, and whether you're prepared to do something meaningful with that insight.
Because optimising your services without evolving your culture isn't optimisation at all. It's just rearranging the symptoms while leaving the cause untouched. And that's a recipe for disappointment, for both your customers and your people.
The mirror effect is real. The only question is whether you're ready to look into it.
