Sharing design research findings is a bit like one of 'those' jokes

You had to be there. (Video)

Like one of ‘those’ jokes, design research has the most impact to those who were there in the moment.

In this video – from a presentation hosted at eBay Design in San Francisco – I explain how I try to help client teams discover their own punchline from user research, by designing experiences for them rather than delivering findings to them.

Nine nourishing nuggets

Over the NZ summer, I deliberately made time to nourish my professional self.

Inspiration came from 5 podcasts, 2 books and a 2 short but atmospheric films.

I’d squirrelled dozens of potentially inspiring articles, podcasts and videos over the year, waiting to filter them for quality, then absorb them… undistracted, to the sound of cicadas.

A few were memorable, including:

  • A peculiar ‘outsider view’ on UX research,
  • Podcasts on social research and why people do what they do,
  • Interviews with designers I admire about their work, and approaches to product development,
  • A couple of rather chilling ethno-books by people who gave their all to understand another people.
  • A couple of gorgeous videos spotlighting the beauty of heavy manufacturing – sheffield style,
  • A short surf adventure in Iceland, captured in inimitable ironic Kiwi narrative.
  • … and some envy-inducing lifestyle portraits of people who’ve made creativity into a lifestyle,

Here’s a snapshot of each, and why I found it worthy brain fodder for my work in design / research:

5 Podcasts

UX seduction at Etsy
Journalism meets UX research. This account of the interviewee’s perspective in a ‘usability test’ is a surreal experience given I’ve conducted hundreds of these sessions in my time.
The host of the podcast feels more like they’ve been part of an experiment than ‘helping improve a product’, and (tries to) delve into the ethics behind the way e-commerce sites steer our minds.
Hearing this makes me want to interview the interviewees from user research sessions to find out what level of cynicism and undercurrents of curiosity really does ship as standard with participants in these studies.

‘The big interview’ with Thomas Heatherwick & Monocle
I used to ride past his office in London when the models for his ‘rolling bridge’ were in the window, but the bridge hadn’t become a reality.

Now it’s in his back catalogue, and Terence Conran has declared Thomas Heatherwick ‘the Leonardo Da Vinci of our time. … a handle he’s clearly not comfortable with.
Though he gets a bit earnest at times, I was taken by his lack of ego. A humble designer untethered to a medium with a solid worship of idea over process.

He reminds me at times of the profile of Marc Newson, who in ‘Urban Spaceman’ share the same comments about being material and subject matter agnostic as a designer.

Thinking allowed
Fascinating sociology podcasts from the BBC. Laurie, the curious interviewer frames up myriad topics beautifully, then chats with people who’ve studied people in that context.

It’s good stuff. Highly conversational, so you don’t need to wade through the academic fluff as you find out about things like what motivates middle class kids who want for nothing but become drug dealers, or changing attitudes to how we navigate our careers, to children’s changing attitude to money.

Perfect podcasts for a walk around the block. If your block takes about 20 mins.

Paul Adams on Product
Never short on an opinion, and always worth listening to, Paul Adams is quite the influential voice on what it takes to make a great digital product.

We worked together at Flow, a company since absorbed into Europe’s largest UX consulting agency. Now – after serving a Silicon Valley sentence – He’s putting his learnings into play at Intercom, in Dublin, where he’s using what he refers to as the ’6-6-6’ roadmap for product development.

For those who (like me) suffer fatigue from the newfangled recipes for success, it’s summed up here as a 2min read, but the podcast is worth a listen to any product strategy or team leader.

Guerilla interviews in South Auckland 
This is guerrilla street interviewing at it’s best, by a master who really connects.
John Campbell’s authentic and probing dialogue makes you feel like you’re there with him. This is all laid down with brilliantly executed post production to stitch the story together.
There’s only a couple of these articles, but they are worth a listen, as he interviews people at the low end of the socio-economic spectrum, and very quickly gets down to brass tacks about their day to day struggle to live in our biggest city.

2 books:

On the run, with Alice Goffman

Reading this book is a little like a personal account of living in the series ‘the wire’…
…but instead of an HBO production crew, it’s seen through the lens of an ethnographer.

New York book review calls it an ‘ethnographic classic’, but it’s also been controversial.

Alice, a middle class academic moved in and spent six years living in a troubled Philadelphia neighborhood and saw first-hand how teenagers of African-American and Latino backgrounds are “funneled down the path to prison”.

This is journalism meets ethnography, and you’d expect rigour from the daughter of the “most important sociologist of the last 50 years” … So reading about her in-the field practices of note taking, logging of events etc. .. I shudder to imagine how much data she was wading through while examining these lives at such close range.

Academic sociologists felt she was too close to her subjects and took liberties in the way she wrote, while Journalists, (likely stunned at the depth and richness of her account) simply picked holes in the details, dismissing it’s value as a true account.

If you haven’t got the time to read the book… here’s a TED

Patched. when ethnography goes underground.
This book is the result of New Zealand’s largest ever study of gangs in NZ, with much of the story captured via a long and dangerous ethnography.

“I hung out with the gangs” says Jarrod Gilbert, and the stories he’s dredged up paint a rich and sometimes raw picture of this part of our social history.
He spent six years researching gangs, which meant drinking with them, listening to them, tuning motorbikes together and figuring out what to say and what not to say. He admits he was “on the wrong end of a couple of beatings” and his liver took a beating as well.

This all led to a prize-winning academic book, Patched, but like Alice and her book on life as a fugitive in Philadelphia, This author too has had their work controversially discredited by authority (in this case the Police) because he was too close to the subjects.

 2 Short films

For some eye candy I soaked up these two gems:

Barry Can’t arf Weld.
A totally gorgeous piece of atmosphilm – this short but powerful video essay rips into you with sound and motion.
Follow the journey of a few kilos of molten metal all the way to becoming a railway bogey. It’s so raw, noisy and dirty it makes you want to reach for the Swarfega.

…But then you kinda wish you could don a pair of steel caps and join in the fun in the dark and forbidding bowels of this Sheffield foundry.
Delicious.

‘Brass monkey’ surfing in Iceland.
A somehow timeless surfing ‘roadie’ flick. Filmed in in Iceland of all places by three Kiwi wax-heads mad enough to take this on.
Equal parts warming and super frosty, with the kind of dry, tongue-in-cheek-narration to bring you along on the romance of the trip.

Oh, did I say 9?

… come on, just one more …

As a some-time architect of my own lifestyle. I’m a hoover for inspiration … pondering other people’s existence. … and here at Freunden von Freunden (friends of friends) is where I found a stack:

These are styled portraits showcasing the lives of a privileged few creative people who have made a life from what they love and seek and create. Including a few Kiwis

Ok, and one more makes 11

I’ve also been piecing together a wee story about my own product development – of Mr. Tappy, a mobile UX research tool. I’m as proud as I am surprised with how it’s evolved.

Great to have found the time to indulge, and now share some brain fodder and use some of those muscles which -during the year- only get a 2 minute workout on short articles.

Thanks for reading and here’s to 2016!

Curiosity-tablets

Ethnography. Only the curious need apply

How can a product team gain empathy for their customers and draw meaningful insights if they aren’t driven by their own curiosity?

I’ve been helping client teams to plan and conduct their own design research, ‘going ethno’ with small teams to meet and study their end users in context. Initially I had my reservations, (and many live on) but…

…it’s been a learning experience on both sides:

I generally encourage clients to ride shotgun with me during fieldwork. It’s an engaging way for them to meet their customers, get inside their heads and fall in love with their problems.

Increasingly these teams want a lasting version of design research goodness – learning how to do it for themselves – often as part of a broader move to a customer-centred mindset, and as a rule I’m all-for passing on my approach and techniques.

But where to start? I’m self-taught through running dozens of these projects without a scrap of training, or ever reading a book, so how should I go about passing this goodness on to my clients?

With a mild dose of impostor syndrome, I initially tried up-front ‘ethnography 101’ style coaching, role-playing, ‘primer’ exercises, guerilla research and even wrote ‘how-to’ field guides covering interview and recording techniques etc. – only to be disappointed.

So, why weren’t all these client teams as interested in their own customers as I was?

In search of a tutorial silver bullet and a way to get these clients into the right mindset, I’ve read, gifted, recommended, quoted and paraphrased from all four of these books for my clients:

curiosity-book-covers-455

If in doubt – consult your manual?

These books are great fodder for the aspiring or even seasoned researcher, reminding you that what you do actually is ‘a thing’ …(and you can even call it ethnography) but having tried a few methods of ‘coaching’ I’m not convinced any amount of reading can move the needle on your clients’ curiosity-meter.

…in fact latent curiosity seems all-too-rare regardless how much permission and context you provide or how well you prepare teams upfront to ‘go ethno’.

Exposure to customer-world can ignite this desire to learn, but even well-intentioned members of a product team can fail to gain empathy with their customers or draw meaningful insights if they aren’t driven by their own desire to learn.

Yes, that glimmer of curiosity in your clients’ eye is worth more than all the ‘how to’ books ever published, and on these assignments, my goal is to bring that out in my client. Tossing the books aside, I’ve found it’s way simpler than I thought.

The glimmer of curiosity is a platform to build their skills on, and my response is to go with less ‘how to’ and more ‘let’s do’:

  1. Lay a few ground rules, (rather than a lecture or lesson)
  2. Dive into a live project. (something they care about, not a hypothetical example)
  3. Review and share learnings as you go.
  4. Fuel and follow your team’s curiosity.

It seems all the tips, techniques, handbooks and best intentions aside, it seems real world experience sorts the ‘men from the boys’ in terms of building this desire to learn.

…But the changing and unpredictable nature of peoples’ behaviours and now knowing what you’re going to learn is addictive, and the curiosity and drive to dig deeper can spread by osmosis. So if you’re in a ‘coaching’ role, show them the rewards and they’ll want to make the investment in learning the skills.

So… what about you…?

How have you managed to up-skill your clients in user research?

Has this been deliberate, at their request, or a useful bi-product of attending your fieldwork?

The books I read and shared from were:

Interviewing users. Steve Portigal

Practical ethnography. Sam Ladner

Talking to humans. Giff Constable

Practical empathy. Indi Young

Curious? Go cold turkey to gobble the insights

Curiosity is one of a UX researcher’s most valuable traits, but it’s also a vulnerable one, because it can be dissolved by a little knowledge.

I’ve found it’s handy to have a few hunches in my back pocket, but when I’m trying to understand a customer – the less I know about them, the more curiosity I’ll need to find out.

Wary of this, I work hard to defend my naiveté, particularly during the early stages of a project. I’ll try to be selective about what information I take on the road, and what I leave parked in the office…

Here’s an example of how I try to maintain my curiosity:

At kick-off, I usually help my clients brief a recruiter with criteria to fetch a representative sample of customers*. The recruiter provides a schedule and participant list with granular details of every participant – name, address and three contact methods will be their demographics, customer type, attitudes and attributes which were collected when they were screened. It’s an eye-bleeder, but part of the process.

Design-research-spreadsheet

A recruiter typically provides an ugly-but-data-packed spreadsheet with more than you need to know.

During this process I invariably learn about customer segments, what they mean to the business and a taste of the client’s base level understanding of their customer. It gives some insight into each person I’ll meet, but I find it’s better not to know at this stage.

Start with a blank canvas.

To defend my curiosity, I pick only three of these details** to stick to the car dashboard:

  1. Time of appointment
  2. First name
  3. Address
Spare the details: I leave all the other customer information in the office and out of mind.

Spare the details: I only take the basics on the road.

I do this because…

I want to interview a person, not a ‘customer segment’…

Because I’m starting the interview with such minimal information, I let the customer paint me a picture which brings all those details the surface, and it’ll take every bit of my curiosity to draw them out.

It’s a small detail, but I believe this makes a big difference to the pace and direction of the interview.

For example – on my current project, we’re interviewing a mix of three customer types; subscribers, non-subscribers and ex-subscribers. All three are relevant and I don’t want to be pigeon-holing them in my mind before I’ve walked in the door, or for them to feel like ‘they’ve been picked for a reason’.

If I know she’s an ex-customer, a part of me will be wondering, “why did she cancel her subscription?” I’ll be looking for clues, reading between the lines and may draw this to the surface before she’s had a chance to fully describe her context. Or she might detect I’m on this thread and defend her reasons for leaving the service, which isn’t what I want to hear.

… so I prefer to go in ‘cold-turkey’, letting these details all come out ‘in the wash’ in the customers words as part of a natural, unbiased conversation. (at least, that’s the way I want it to feel for the customer).

There’s plenty of time for answers later, these are valuable and expected outputs of any design research project, but I’ve found NOT knowing the answer is the best possible position to be in when you’re heading into the field to interview and observe people interacting with your product.

This is part of trusting your instinct as a researcher, being comfortable with ambiguity and being ‘in the dark’.

Earlier in the year I wrote about how a Calligrapher / Monk / and Ex- Xerox PARC innovation researcher approaches these uncomfortable research situations: Humble pie, served on a bed of chaos.

…but he doesn’t mention being in the dark with a cold turkey?


*If you’re going to invest in spending some time with your customers, it pays to be sure your sample is representative of your customer base and represents the challenges . I believe this is worth taking seriously, and well worth paying a recruitment firm to handle for you.

**Sometimes I’ll add the age and/or gender of the participant. Gender is not always obvious from the name and in mixed households having a little more information helps you get your greeting right at the door.

8.5 Postcards from People-watcher’s Paradise

Montage

Numerous occupational hazards beset the professional observer of people, their contexts and behaviours.

Absorbing everything in a city as stimulating as Tokyo results in visual and mental overload. Without horses’ blinkers to turn down my senses from default ‘sponge’ setting, it’s taken me several days to process, but here goes…

On day two I met with a design anthropologist well-versed with Tokyo’s back-street charm and a man also unable to switch off the investigative mindset and his need to filter and pattern-spot in such a visually rich environment.

Yep, I was doomed to notice, notice and notice some more.

Here are eight and-a-half of my favourite themes from this wonderful city:

Kerbside clawback.

In a spectacularly vertical city, gutters become fair game for a few inches of horizontal gain where it’s needed, at street level.

Gutters made more user friendly by those who interact with them most.

Honouring the craftsman.

Absolute respect for the makers of everyday things. Mastery of a trade celebrated at an individual level.

Tweezer geezer (top) is a third generation craftsman.

Display perfection.

The art of retail merchandising taken seriously. Objects more beautifully composed and presented, and with far more consideration than I’m used to.

Artfully presented edibles, neatly stacked paper and all labels to the front.

Service culture.

This takes some getting used to. A minute seems like two or three at the complete attention of staff-members as they meticulously wrap and present your purchase. Working in silence and harmony, each knows their role. Every detail executed to perfection.

A bomb could go off while your items are being wrapped and the staff wouldn't flinch.

A bomb could go off while your items are wrapped and the staff wouldn’t flinch.

Visual calm.

The zen of traditional Japanese design. Rhythm, space, balance, warmth, grids, geometry, symmetry.

The Okura. Steve Jobs’ favourite hotel. Mmm.

Visual chaos.

Enough graphic stimulation to make your retinas bleed. Onslaught of type, characters, colour, contrast and a near-zero tolerance policy on negative space.

Half a step into a 100 Yen shop and the information ambush hits you.

Stationery supermarket.

I met my match in the Japanese love of expression through the hand-drawn and written. Pen, paper and ink. Every colour, weight, grade. Acres of it.

Stripes seem to be in fashion for those who like their pen and paper porn.

Greening the fringes.

What little space for green in this city is revered. Where planting doesn’t occur through civic planning, it’s created and nurtured by residents, usually in pot plants.

A far cry from mowing the verge.

Pride and care of doorstep plantings – a far cry from ‘mowing the verge’.

And something nobody tells you about Tokyo, and no photographs can convey…

The calm. A truly human level of politeness and respect.

I now understand Paris syndrome but for me, Tokyo syndrome appears to offer the opposite symptoms – Expectations exceeded.

Whilst in town I presented at Tokyo UX Talk, building on one of my favourite topics… visualising UX research. Thanks to Tom and the crew there for hosting.

My sharpest user research analysis tool


I’ve found it’s easier to ‘see the wood for the trees’ if you’re chopping them with a sharp axe.

Yep, I just had my usual cord of firewood dumped by the shed and once again I’m finding it’s a useful medium when analysing data from a UX research study.

I’ve just had a week on the road interviewing people in their homes and am now faced with the mammoth task of reviewing all my footage / notes / photos and artefacts from the trip, then making sense of it.

A formally trained researcher might call this process extraction, collation, analysis and synthesis of data. For many like me who come into research ‘through the side door’ (like I did from the surf industrythere’s a certain mystery to the process, and it can take a few projects to get comfortable with it. What’s more, it can be straight out daunting…

…yes, a bit like a truckload of firewood needing to be cut, sorted and stacked into piles.

… Back to the pile of data though and most likely your first encounters will involve shuffling hundreds of sticky notes round the walls of a small room, bumping into furniture and getting high on solvent-based markers. There’s a lot of pattern spotting and theme building and as a rule it’s a hugely immersive process.

Time can equally stand still, or race by, and your brain aches under the weight of a thousand echos – things you saw, heard or felt during your interviews.

T I M E   &   S P A C E

I’ve found it’s important to step away from the piles of sticky notes, into a new environment where your mind can wander. Running or the gym might be your thing, but for me, it’s chopping wood.

A monotonous task like chopping, sorting and stacking firewood is a perfect partner to working through all that data.

I escape the pastel patchwork walls and kill those echos in a single chop of the axe as I try to guess which way the log will split, or whether I’ll need the bigger axe for the knotty pieces?, which way the grain goes? and so on.

Time can play tricks on me in this mode too, but I surrender to it. As I’m splitting and stacking away I let my own thoughts come into play alongside the project objectives. This is where the strongest insights emerge for me, and they seem to come from instinct.

There’s something magic about walking back into the ‘war room’ with a few splinters and a fresh perspective, or even a challenge to the direction you’re on, and I’ve found it comes not from total immersion, but from giving yourself the space to let your own mind sort through the findings.

Design thinking – One size doesn’t fit all

“It’s not about going from left to right and some magic happens on the other side, it’s about understanding the intention”.

…Said Director of Design Innovation at Intuit, a stop on the Bettter by Design Study Tour I was part of in 2012.

During our visit, Intuit shared how design thinking changed the culture, and profit of the company (eventually).

Their story: How they tried and failed to install ‘design as a process’ into their teams, arriving at a more engaging and successful model of ‘principles’.

A couple of key points I took away:

Design thinking – to the rescue?
With a history of incremental usability improvements but no real innovation, Intuit took a big swig from the design thinking cup. Their aim was to integrate design thinking into the business, to be more user-focused – exceeding customer expectations, rather than just meeting them.

Things didn’t go as planned…

“We made a mistake in that we started with design thinking as a process, when we brought a process back to Intuit, they puked all over it. Because in a culture where; product development has an agile process, marketing have a go-to-market process and legal have a compliance process, they couldn’t reconcile the design thinking process on top of theirs, so they did nothing”.

So, the conventional design thinking process wasn’t flexible enough for the realities of their culture and practice, and it simply wasn’t engaging teams.

Principles, not process.
To replace the rigid ‘process’ approach, Intuit arrived at three principles to underline all development work- teams could use whatever methods they liked, so long as they adhered to those principles.

So, how did that go?

“A seminal moment in our journey was when we took the process of design thinking and made it into principles. It’s not about going from left to right and some magic happens on the other side, it’s about understanding the intention behind these principles, then you can make it your own”.

“We have watched teams come up with their own methods and tools at any time in the process and it totally works. Thats when we saw uptake in the culture, when we started to see behaviours change, when we gave them permission to make it their own”.

Here are their principles:

  1. Deep Customer Empathy (Know your customers better than they know themselves)
  2. Go Broad to go Narrow (Quantity of solutions, then focus)
  3. Rapid Experimentation with Customers (Prototype, test, iterate)

Sounds like a win to me, especially if this has taken hold in an organisation of thousands.

So, how do Intuit involve customers in their design process?
To deliver on their first principle, (apart from their dedicated UX team) Intuit has committed to getting their teams out of the office and into the context of their customers using their products. Unsurprisingly, this has proven to build empathy for the customer, and as a positive bi-product, engagement with the ongoing design process.

Two big wins.

“We went from listening and fixing problems, to watching to find what they really need but can’t tell us.

This changed the way the organisation makes decisions by watching people’s behaviours versus listening to what they say”.

If you’re wanting to institutionalise design thinking, there’s a video on the Adaptive Path website which tells this story from another Intuit insider’s viewpoint http://youtu.be/HrxD_BaZlcU

All-hands-on-deck …for rapid user insights

Taking notes form the user's point of view...This year I’ve surprised myself by recommending some super short approaches to user research.

When there’s no time, money or buy-in for a ‘full noise’ project I’ve been running a 2 day process where I put my clients in the research seat as they work together to make their own observations, draw their own conclusions and insights.

It felt risky and compromised at first, but it’s working out well so far.

Here’s how…..

(Once the objectives and scope are nailed down)

  • I invite stakeholders to attend and observe interviews with customers.
  • I set the stakeholders up to take notes.
  • Then facilitate interviews with paid participants.
  • Between sessions we gasp for breath and I draw out the top-of-mind observations from each stakeholder.
  • After the last session, I guide them through a hands-on exercise where they match and group individual observations into themes.
  • Together we agree on what these mean for the design/business and prioritise them into an action list.

This is a collaborative, intense and compressed way to work but has massive value to the client. … even if you are exhausted at the end of it.

Some things I’ve learned from working this way:

PLANNING:

Critically, this requires time investment and commitment from the stakeholder team – be crystal clear from the start that this is totally a ‘get out what you put in’ scenario. Participation is required if the client is going to see value.

It’s best to have a mix of stakeholders involved, different parts of the business, levels of seniority, familiarity with the product, market etc.

I can’t imagine doing it justice with less than 3 stakeholders.

Try to make this an off-site activity to minimise distractions.

Make sure food for them and you is arranged in advance. The sessions will be almost back to back so there will be no skipping off to lunch.

Recruitment – You should consider all-day ‘standby’ participants in case of a ‘no-show’.

THE SESSIONS:


Stakeholders need a strong briefing around observation. Reinforce that it’s a team effort, several stakeholders observing the same behaviour can take different meaning away – It’s all valuable.

Keep note taking physical and portable (paper / sticky notes).

Don’t be precious about format, it’s most important that notes are actually taken, not how.

Suggest notes are written from the customer’s point of view. This helps the stakeholder to think through what they are writing, and these ‘quotes’ really come to life during the analysis.

For a usability type project, you could have a sheet of paper for each participant with columns; Where, What and How – Where was the customer at, What did they say/do, How does it impact their experience.

Pinning the objectives up on the wall can remind observers what they are looking for.

Start a ‘discuss’ list and encourage observers to add items as they come up rather than talk through the session.

You need 5-10 mins between each session to conclude what was learned, what was confirmed etc. Asking each stakeholder to write down them share their ‘Top 5’ observations works well.

AFTER THE FINAL SESSION:

Aim for a 2 hour analysis and wrap-up.

Collate all the notes and get them up on walls, grouped by customer, topic etc.

Have everyone spend time (10-15 mins) scanning the data and writing down what they feel are key observations. Go for quantity. 100 is a good start.

Go for some sort of ‘KJ’ collaborative analysis to group individual observations into themes. Name each theme and what it means for the product and customer.

Roll this into a prioritisation exercise by ranking / voting, plotting on a scale etc.

OUTCOMES FOR THE CLIENT:

Making decisions based on first hand observations is a powerful experience.

Getting answers in hours to questions which have been hovering for weeks is a liberating feeling for clients.

Clients arrive at conclusions and reach consensus and create the output together.

This approach can also show the client it’s something they can do themselves.

… and of course, questions emerge which they didn’t know they needed to answer.

Suddenly… where time, budget and buy in for customer research was lacking… it miraculously appears!

I was nudged over the fence into taking this approach by Dana Chisnell, so thanks Dana for the nudge!

I’d love to hear other people’s experience with this…
In another blog post I’ll tell you how it goes when you send the stakeholders out into the field to do their own research.

Customer insight from… the Yellow Pages

The dull thud of a phone book hitting the desk. …Probably not a sound you’ve heard since the 90’s, but the humble yellow book, and it’s smaller, newer, blue cousin can be useful to explain the value of customer insights, especially those gathered in context…

20 years ago when the Thomson Directory went into battle with the ubiquitous Yellow Pages in the UK they wanted a point of difference – and to become the ‘most reached for’ directory over their competitor…

…By visiting people’s homes they saw the Yellow Pages not only next to the phone, but in drawers, under stairs, propping up computer monitors etc. Importantly, they noticed peoples’ behaviour – They stacked smaller books on top of  larger books.

Thomson used these behavioural insights to their advantage, producing a smaller book so it would sit on top, and be the first directory people grabbed.

The purpose, function and content remained unchanged, but a practical human behaviour sparked this significant change in the design and form factor of their product.

I’m not sure there’s a digital equivalent to ‘stacking’ items like this… but can you think of other products or services which have been shaped so fundamentally by behavioural insights?

Thanks Simon in London for the photos
