Early in my career, I spent a Saturday afternoon in a kitchen in Tokyo watching a man in his late twenties make coffee. This was just before we sat down for an ethnographic interview. His apartment was small and carefully arranged. A shelf above the counter held four handmade ceramic cups, each one seemingly chosen with care. A drip machine sat to one side, functional and unremarkable. He used it on weekdays.
On weekends, he pulled out a special roast, a jug of mountain spring water, a hand grinder, a ceramic dripper, a gooseneck kettle, and a rather nice kitchen scale. He set them out in a specific order, each item placed with the kind of attention you give to objects that matter to you. The grinder was a Porlex, the steel barrel catching the light from the window. The dripper was a Hario V60 in white ceramic, cradled in a wooden stand he had found at a market in Yanaka. The manual coffee-making process took eighteen minutes.
What struck me was the stillness. For those eighteen minutes, his phone stayed on the counter face down. He watched the water as he poured, adjusting the stream by feel. When the last drops of water fell through the filter, he lifted the cups and stood at the window for a moment, watching the steam rise before sitting down and placing a cup in front of me. The kitchen smelled of fresh grounds and cedar from the wooden stand. Everything about the sequence was deliberate, and everything about his posture said: this has meaning.
I asked him why he had gone to all the trouble. He paused. Then he said something I have carried with me for twenty years: "The drip machine makes coffee. This makes my morning."
That remark contains the seed of everything I have learned about why some products create lasting relationships with their users, and why most do not.
As I came to understand it, he was describing a psychological relationship with an everyday object. The ritual gave him a sense of control over the start of his day, marking a transition. The tools, chosen with care, said something about who he was. The sensory experience: the smell of the grind, the sound of the pour, the warmth of the cup, delivered a layered reward that a button press could never replicate. Identity, control, pleasure. Three fundamental drivers, woven into eighteen minutes of a Saturday morning.
2 kinds of ambition
Most product organisations are exceptionally good at improvement. They optimise performance, reduce friction, extend capability, and close the gap on competitors. That work is necessary and worth doing well. But there is a different kind of product ambition that sits beyond optimisation — one that changes what people do, how they think about a category, and how a product participates in their sense of who they are. This is the kind of product that makes competitors’ roadmaps look beside the point, because it has shifted the terrain entirely.
The challenge is that these two ambitions look superficially similar in the early stages of development. Both begin with consumer insight. Both move through the process of concept development and validation. Both require engineering, design, and commercial judgment. The difference lies in the depth at which the consumer insight operates and in whether the concept seeks improvement within an existing frame or introduces an altogether different one.
Organisations that keep these two ambitions clearly separated tend to make better decisions about both — about when to optimise, and when to ask a more fundamental question about what the category could become.
A different frame
Some products improve the experience of a category. Others redefine the category. The second kind changes behaviour rather than simply refining an existing one, introduces a new mental model rather than sharpening the current one, and creates in the people who encounter it a response closer to wonder than satisfaction. Crucially, this ambition is not separate from commercial performance. These are products that build momentum precisely because they have moved the terms of competition to a terrain where the existing alternatives have no answer.
This is what I mean by deep innovation, and it is worth being precise about what that involves.
Category-defining products do not compete on the existing scorecard. They introduce a new one.
Five characteristics tend to mark deep innovation in the field:
- It changes behaviour, introducing something new rather than making an existing behaviour easier.
- It asks people to think about a category in a fundamentally different way.
- It activates the full psychological landscape of the person using it, not just one dimension of performance.
- It produces a specific response on first encounter: surprise followed by a shift in understanding.
- Almost without exception, it scores poorly when assessed against the criteria of the existing category, because those criteria were designed to evaluate what came before.
That last point is worth dwelling on. The evaluation frameworks that most organisations use are built to measure incremental improvement. They reward what is familiar and comparable. A deep innovation concept, by definition, almost always brings value dimensions that the current scorecard cannot capture. If a new concept scores well on every existing criterion, it is very likely an incremental improvement. The concepts that create new categories tend to introduce new criteria altogether.
Beneath the specification
Across two decades and more than 16,000 consumer interactions, in their homes, cars, and workspaces, one pattern has proven consistent across categories, cultures, and price points. The products that create lasting attachment are those that connect with people at a psychological depth that optimisation and new features cannot reach.
These three psychological drivers — identity, control, and pleasure — are the structural layer beneath every strong product attachment. The man in Tokyo was not choosing between two coffee-making methods based on taste or even convenience. He was, I observed, choosing a ritual over convenience, one that spoke to who he was, marking a transition (a ritual) from rest to action that gave him a sense of authority at the start of his day, and delivering a layered sensory reward that a button press could not deliver.
Traditional consumer research tends to surface preferences and stated needs. Those are the realm of the rational. What it often misses is the psychological substrate beneath those preferences: the drivers that explain why someone refuses to switch to a technically superior alternative, or why a product that ticks every rational box can still feel hollow in the hand.
Accessing that layer requires a different approach to research: focusing on context, attention to behaviour and storytelling rather than opinion and preference, and the patience to sit with ambiguity until patterns resolve into something actionable.
The Dyson lesson
The Dyson DC01, introduced in 1993, is a useful illustration of where incremental improvement ends and deep innovation begins. The vacuum market at the time was mature and converging. Every manufacturer was refining the same basic architecture.
Dyson’s cyclone technology was a genuine engineering advance, but what made the DC01 a category-defining product was not the engineering alone.It was the transparent bin.
For the first time, people could see what they had removed from their floors. Vacuuming shifted from a chore into something closer to a demonstration of competence. The product activated identity — I am someone who takes my home seriously, and this object reflects that. It activated control — the visible, direct feedback loop between effort and result. It activated pleasure — the sensory satisfaction of watching the cyclone work. The relationship between a person and the act of cleaning has changed.
Competitors spent years trying to match Dyson’s suction figures. What they were slower to recognise was that Dyson had introduced entirely new evaluation criteria: visibility, the feeling of effectiveness, the experience of the product as an object worth displaying rather than hiding in a cupboard. The existing scorecard simply did not apply.
Reading your roadmap
The characteristics of deep innovation offer a practical filter for any product portfolio. For each project on the board, it is worth asking four questions:
- Does this propose a new behaviour, or does it help people do the same thing more efficiently?
- Does it require a new mental model, or can it be improved within the existing one?
- Does it engage identity, control, and pleasure across the full psychological landscape, or does it optimise along a single dimension?
- When you describe it to someone encountering it for the first time, do they pause and lean forward, or do they nod politely and move on?
The pause is the signal. It is the moment when a product has reached beyond the expected and into territory the consumer had not imagined. Products that consistently produce that response are operating in deep innovation territory. Products that produce polite acknowledgement are incremental improvements, potentially valuable, but unlikely to redefine the category.
The cost of staying inside the current frame accumulates gradually. It shows up as a product roadmap that increasingly resembles the competition’s, as upgrade cycles that lengthen because consumers can no longer perceive a meaningful difference, as a category ceiling that everyone on the team can sense but nobody has a plan to move beyond. That cost is real. It tends to become visible only when someone outside the category first redefines it.
The man in Tokyo had already chosen his answer. The question for any product team is whether they are building the machine or building the morning.
