The Five Senses Framework
A ready-made, MECE way to break down an experience problem.
Some problems aren't about numbers — they're about how something feels. Why does one cafe feel premium and the one next door feel cheap? When the question is about experience or perception, the five senses give you a ready-made, naturally MECE way to break down how it's experienced.
TL;DR · Key Takeaways
What you will be able to do
- Recognise when a problem is about experience or perception rather than numbers.
- Use the five senses as a ready-made MECE structure for that experience.
- Map what the customer perceives across all five, then isolate the failing sense.
- Keep it in reserve for experience and brand-moment cases, not general business problems.
The five lenses
Sight (look, design, lighting), sound (music, noise, acoustics), smell (scent, freshness), taste (where relevant — food, drink), and touch (texture, materials, comfort). Together they form a complete, non-overlapping checklist of everything a person physically perceives in a moment — which is why they're a clean MECE split for an experience.
How to use it
For an experience problem, walk all five senses to map what the customer actually perceives, then find the sense that's letting you down. It's a niche tool — reach for it on experience, retail-environment, and brand-moment cases, not on numbers-driven problems where it would just be decoration.
Why it's genuinely MECE
Most ad-hoc breakdowns of ‘experience' overlap or leave gaps. The five senses don't — they're mutually exclusive and collectively exhaustive of physical perception, which is exactly why they make such a clean structuring device when the problem fits.
Diagnosing a feel
A coffee chain's new outlet has great coffee and prices but customers say it feels ‘cheap' and don't linger. How would you break that down?
Since this is an experience problem, I'd break it down by the five senses. Sight: lighting too bright or harsh, cluttered layout, cheap-looking finishes? Sound: no music, or noisy and echoey? Smell: is the coffee aroma actually reaching customers, or masked? Touch: hard seating, flimsy cups, sticky tables? Taste is fine — they said the coffee's good. My bet is the ‘cheap' feel is mostly sight and touch — lighting and materials — so I'd focus the diagnosis there.
Uses the senses as the structure.
The senses gave the candidate an instant, complete structure for a fuzzy ‘it just feels off' problem — which is exactly when this niche lens earns its place.
Where this connects
It's a specialised structuring device — a sibling to the broader structuring tools in Structuring Fundamentals, useful when a problem is sensory or experiential rather than financial.
