Picture this: You’re in a meeting room at your tech company, and two people are having what looks like the same conversation about the same design problem. One is talking about whether the team has the right skills to tackle it. The other is diving deep into whether the solution actually solves the user’s problem. Same room, same problem, completely different lenses.

This is the beautiful, sometimes messy reality of having both a Design Manager and a Lead Designer on the same team. And if you’re wondering how to make this work without creating confusion, overlap, or the dreaded “too many cooks” scenario, you’re asking the right question.

The traditional answer has been to draw clean lines on an org chart. The Design Manager handles people, the Lead Designer handles craft. Problem solved, right? Except clean org charts are fantasy. In reality, both roles care deeply about team health, design quality, and shipping great work. 

The magic happens when you embrace the overlap instead of fighting it—when you start thinking of your design org as a design organism.

The Anatomy of a Healthy Design Team

Here’s what I’ve learned from years of being on both sides of this equation: think of your design team as a living organism. The Design Manager tends to the mind (the psychological safety, the career growth, the team dynamics). The Lead Designer tends to the body (the craft skills, the design standards, the hands-on work that ships to users).

But just like mind and body aren’t completely separate systems, so, too, do these roles overlap in important ways. You can’t have a healthy person without both working in harmony. The trick is knowing where those overlaps are and how to navigate them gracefully.

When we look at how healthy teams actually function, three critical systems emerge. Each requires both roles to work together, but with one taking primary responsibility for keeping that system strong.

The Nervous System: People & Psychology

Primary caretaker: Design Manager
Supporting role: Lead Designer

The nervous system is all about signals, feedback, and psychological safety. When this system is healthy, information flows freely, people feel safe to take risks, and the team can adapt quickly to new challenges.

The Design Manager is the primary caretaker here. They’re monitoring the team’s psychological pulse, ensuring feedback loops are healthy, and creating the conditions for people to grow. They’re hosting career conversations, managing workload, and making sure no one burns out.

But the Lead Designer plays a crucial supporting role. They’re providing sensory input about craft development needs, spotting when someone’s design skills are stagnating, and helping identify growth opportunities that the Design Manager might miss.

Design Manager tends to:

• Career conversations and growth planning
• Team psychological safety and dynamics
• Workload management and resource allocation
• Performance reviews and feedback systems
• Creating learning opportunities

Lead Designer supports by:

• Providing craft-specific feedback on team member development
• Identifying design skill gaps and growth opportunities
• Offering design mentorship and guidance
• Signaling when team members are ready for more complex challenges

The Muscular System: Craft & Execution

Primary caretaker: Lead Designer
Supporting role: Design Manager

The muscular system is about strength, coordination, and skill development. When this system is healthy, the team can execute complex design work with precision, maintain consistent quality, and adapt their craft to new challenges.

The Lead Designer is the primary caretaker here. They’re setting design standards, providing craft coaching, and ensuring that shipping work meets the quality bar. They’re the ones who can tell you if a design decision is sound or if we’re solving the right problem.

But the Design Manager plays a crucial supporting role. They’re ensuring the team has the resources and support to do their best craft work, like proper nutrition and recovery time for an athlete.

Lead Designer tends to:

• Definition of design standards and system usage
• Feedback on what design work meets the standard
• Experience direction for the product
• Design decisions and product-wide alignment
• Innovation and craft advancement

Design Manager supports by:

• Ensuring design standards are understood and adopted across the team
• Confirming experience direction is being followed
• Supporting practices and systems that scale without bottlenecking
• Facilitating design alignment across teams
• Providing resources and removing obstacles to great craft work

The Circulatory System: Strategy & Flow

Shared caretakers: Both Design Manager and Lead Designer

The circulatory system is about how information, decisions, and energy flow through the team. When this system is healthy, strategic direction is clear, priorities are aligned, and the team can respond quickly to new opportunities or challenges.

This is where true partnership happens. Both roles are responsible for keeping the circulation strong, but they’re bringing different perspectives to the table.

Lead Designer contributes:

• User needs are met by the product
• Overall product quality and experience
• Strategic design initiatives
• Research-based user needs for each initiative

Design Manager contributes:

• Communication to team and stakeholders
• Stakeholder management and alignment
• Cross-functional team accountability
• Strategic business initiatives

Both collaborate on:

• Co-creation of strategy with leadership
• Team goals and prioritization approach
• Organizational structure decisions
• Success measures and frameworks

Keeping the Organism Healthy

The key to making this partnership sing is understanding that all three systems need to work together. A team with great craft skills but poor psychological safety will burn out. A team with great culture but weak craft execution will ship mediocre work. A team with both but poor strategic circulation will work hard on the wrong things.

Be Explicit About Which System You’re Tending

When you’re in a meeting about a design problem, it helps to acknowledge which system you’re primarily focused on. “I’m thinking about this from a team capacity perspective” (nervous system) or “I’m looking at this through the lens of user needs” (muscular system) gives everyone context for your input.

This isn’t about staying in your lane. It’s about being transparent as to which lens you’re using, so the other person knows how to best add their perspective.

Create Healthy Feedback Loops

The most successful partnerships I’ve seen establish clear feedback loops between the systems:

Nervous system signals to muscular system: “The team is struggling with confidence in their design skills” → Lead Designer provides more craft coaching and clearer standards.

Muscular system signals to nervous system: “The team’s craft skills are advancing faster than their project complexity” → Design Manager finds more challenging growth opportunities.

Both systems signal to circulatory system: “We’re seeing patterns in team health and craft development that suggest we need to adjust our strategic priorities.”

Handle Handoffs Gracefully

The most critical moments in this partnership are when something moves from one system to another. This might be when a design standard (muscular system) needs to be rolled out across the team (nervous system), or when a strategic initiative (circulatory system) needs specific craft execution (muscular system).

Make these transitions explicit. “I’ve defined the new component standards. Can you help me think through how to get the team up to speed?” or “We’ve agreed on this strategic direction. I’m going to focus on the specific user experience approach from here.”

Stay Curious, Not Territorial

The Design Manager who never thinks about craft, or the Lead Designer who never considers team dynamics, is like a doctor who only looks at one body system. Great design leadership requires both people to care about the whole organism, even when they’re not the primary caretaker.

This means asking questions rather than making assumptions. “What do you think about the team’s craft development in this area?” or “How do you see this impacting team morale and workload?” keeps both perspectives active in every decision.

When the Organism Gets Sick

Even with clear roles, this partnership can go sideways. Here are the most common failure modes I’ve seen:

System Isolation

The Design Manager focuses only on the nervous system and ignores craft development. The Lead Designer focuses only on the muscular system and ignores team dynamics. Both people retreat to their comfort zones and stop collaborating.

The symptoms: Team members get mixed messages, work quality suffers, morale drops.

The treatment: Reconnect around shared outcomes. What are you both trying to achieve? Usually it’s great design work that ships on time from a healthy team. Figure out how both systems serve that goal.

Poor Circulation

Strategic direction is unclear, priorities keep shifting, and neither role is taking responsibility for keeping information flowing.

The symptoms: Team members are confused about priorities, work gets duplicated or dropped, deadlines are missed.

The treatment: Explicitly assign responsibility for circulation. Who’s communicating what to whom? How often? What’s the feedback loop?

Autoimmune Response

One person feels threatened by the other’s expertise. The Design Manager thinks the Lead Designer is undermining their authority. The Lead Designer thinks the Design Manager doesn’t understand craft.

The symptoms: Defensive behavior, territorial disputes, team members caught in the middle.

The treatment: Remember that you’re both caretakers of the same organism. When one system fails, the whole team suffers. When both systems are healthy, the team thrives.

The Payoff

Yes, this model requires more communication. Yes, it requires both people to be secure enough to share responsibility for team health. But the payoff is worth it: better decisions, stronger teams, and design work that’s both excellent and sustainable.

When both roles are healthy and working well together, you get the best of both worlds: deep craft expertise and strong people leadership. When one person is out sick, on vacation, or overwhelmed, the other can help maintain the team’s health. When a decision requires both the people perspective and the craft perspective, you’ve got both right there in the room.

Most importantly, the framework scales. As your team grows, you can apply the same system thinking to new challenges. Need to launch a design system? Lead Designer tends to the muscular system (standards and implementation), Design Manager tends to the nervous system (team adoption and change management), and both tend to circulation (communication and stakeholder alignment).

The Bottom Line

The relationship between a Design Manager and Lead Designer isn’t about dividing territories. It’s about multiplying impact. When both roles understand they’re tending to different aspects of the same healthy organism, magic happens.

The mind and body work together. The team gets both the strategic thinking and the craft excellence they need. And most importantly, the work that ships to users benefits from both perspectives.

So the next time you’re in that meeting room, wondering why two people are talking about the same problem from different angles, remember: you’re watching shared leadership in action. And if it’s working well, both the mind and body of your design team are getting stronger.

“Language is not merely a set of unrelated sounds, clauses, rules, and meanings; it is a totally coherent system bound to context and behavior.” — Kenneth L. Pike

The web has accents. So should our design systems.

Design Systems as Living Languages

Design systems aren’t component libraries—they’re living languages. Tokens are phonemes, components are words, patterns are phrases, layouts are sentences. The conversations we build with users become the stories our products tell.

But here’s what we’ve forgotten: the more fluently a language is spoken, the more accents it can support without losing meaning. English in Scotland differs from English in Sydney, yet both are unmistakably English. The language adapts to context while preserving core meaning. This couldn’t be more obvious to me, a Brazilian Portuguese speaker, who learned English with an American accent, and lives in Sydney.

Our design systems must work the same way. Rigid adherence to visual rules creates brittle systems that break under contextual pressure. Fluent systems bend without breaking.

Consistency becomes a prison

The promise of design systems was simple: consistent components would accelerate development and unify experiences. But as systems matured and products grew more complex, that promise has become a prison. Teams file “exception” requests by the hundreds. Products launch with workarounds instead of system components. Designers spend more time defending consistency than solving user problems.

Our design systems must learn to speak dialects.

A design dialect is a systematic adaptation of a design system that maintains core principles while developing new patterns for specific contexts. Unlike one-off customizations or brand themes, dialects preserve the system’s essential grammar while expanding its vocabulary to serve different users, environments, or constraints.

When Perfect Consistency Fails

At Booking.com, I learned this lesson the hard way. We A/B-tested everything—color, copy, button shapes, even logo colors. As a professional with a graphic design education and experience building brand style guides, I found this shocking. While everyone fell in love with Airbnb’s pristine design system, Booking grew into a giant without ever considering visual consistency.  

The chaos taught me something profound: consistency isn’t ROI; solved problems are.

At Shopify. Polaris () was our crown jewel—a mature design language perfect for merchants on laptops. As a product team, we were expected to adopt Polaris as-is. Then my fulfillment team hit an “Oh, Ship!” moment, as we faced the challenge of building an app for warehouse pickers using our interface on shared, battered Android scanners in dim aisles, wearing thick gloves, scanning dozens of items per minute, many with limited levels of English understanding.

Task completion with standard Polaris: 0%.

Every component that worked beautifully for merchants failed completely for pickers. White backgrounds created glare. 44px tap targets were invisible to gloved fingers. Sentence-case labels took too long to parse. Multi-step flows confused non-native speakers.

We faced a choice: abandon Polaris entirely, or teach it to speak warehouse.

The Birth of a Dialect

We chose evolution over revolution. Working within Polaris’s core principles—clarity, efficiency, consistency—we developed what we now call a design dialect:

Constraint	Fluent Move	Rationale
Glare & low light	Dark surfaces + light text	Reduce glare on low-DPI screens
Gloves & haste	90px tap targets (~2cm)	Accommodate thick gloves
Multilingual	Single-task screens, plain language	Reduce cognitive load

Result: Task completion jumped from 0% to 100%. Onboarding time dropped from three weeks to one shift.

This wasn’t customization or theming—this was a dialect: a systematic adaptation that maintained Polaris’s core grammar while developing new vocabulary for a specific context. Polaris hadn’t failed; it had learned to speak warehouse.

The Flexibility Framework

At Atlassian, working on the Jira platform—itself a system within the larger Atlassian system—I pushed for formalizing this insight. With dozens of products sharing a design language across different codebases, we needed systematic flexibility so we built directly into our ways of working. The old model—exception requests and special approvals—was failing at scale.

We developed the Flexibility Framework to help designers define how flexible they wanted their components to be:

Tier	Action	Ownership
Consistent	Adopt unchanged	Platform locks design + code
Opinionated	Adapt within bounds	Platform provides smart defaults, products customize
Flexible	Extend freely	Platform defines behavior, products own presentation

During a navigation redesign, we tiered every element. Logo and global search stayed Consistent. Breadcrumbs and contextual actions became Flexible. Product teams could immediately see where innovation was welcome and where consistency mattered.

The Decision Ladder

Flexibility needs boundaries. We created a simple ladder for evaluating when rules should bend:

Good: Ship with existing system components. Fast, consistent, proven.

Better: Stretch a component slightly. Document the change. Contribute improvements back to the system for all to use.

Best: Prototype the ideal experience first. If user testing validates the benefit, update the system to support it.

The key question: “Which option lets users succeed fastest?”

Rules are tools, not relics.

Unity Beats Uniformity

Gmail, Drive, and Maps are unmistakably Google—yet each speaks with its own accent. They achieve unity through shared principles, not cloned components. One extra week of debate over button color costs roughly $30K in engineer time.

Unity is a brand outcome; fluency is a user outcome. When the two clash, side with the user.

Governance Without Gates

How do you maintain coherence while enabling dialects? Treat your system like a living vocabulary:

Document every deviation – e.g., dialects/warehouse.md with before/after screenshots and rationale.

Promote shared patterns – when three teams adopt a dialect independently, review it for core inclusion.

Deprecate with context – retire old idioms via flags and migration notes, never a big-bang purge.

A living dictionary scales better than a frozen rulebook.

Start Small: Your First Dialect

Ready to introduce dialects? Start with one broken experience:

This week: Find one user flow where perfect consistency blocks task completion. Could be mobile users struggling with desktop-sized components, or accessibility needs your standard patterns don’t address.

Document the context: What makes standard patterns fail here? Environmental constraints? User capabilities? Task urgency?

Design one systematic change: Focus on behavior over aesthetics. If gloves are the problem, bigger targets aren’t “”breaking the system””—they’re serving the user. Earn the variations and make them intentional.

Test and measure: Does the change improve task completion? Time to productivity? User satisfaction?

Show the savings: If that dialect frees even half a sprint, fluency has paid for itself.

Beyond the Component Library

We’re not managing design systems anymore—we’re cultivating design languages. Languages that grow with their speakers. Languages that develop accents without losing meaning. Languages that serve human needs over aesthetic ideals.

The warehouse workers who went from 0% to 100% task completion didn’t care that our buttons broke the style guide. They cared that the buttons finally worked.

Your users feel the same way. Give your system permission to speak their language.

Today’s web is not always an amiable place. Sites greet you with a popover that demands assent to their cookie policy, and leave you with Taboola ads promising “One Weird Trick!” to cure your ailments. Social media sites are tuned for engagement, and few things are more engaging than a fight. Today it seems that people want to quarrel; I have seen flame wars among birders.  

These tensions are often at odds with a site’s goals. If we are providing support and advice to customers, we don’t want those customers to wrangle with each other. If we offer news about the latest research, we want readers to feel at ease; if we promote upcoming marches, we want our core supporters to feel comfortable and we want curious newcomers to feel welcome. 

In a study for a conference on the History of the Web, I looked to the origins of Computer Science in Vienna (1928-1934)  for a case study of the importance of amiability in a research community and the disastrous consequences of its loss. That story has interesting implications for web environments that promote amiable interaction among disparate, difficult (and sometimes disagreeable) people.

The Vienna Circle

Though people had been thinking about calculating engines and thinking machines from antiquity, Computing really got going in Depression-era Vienna.  The people who worked out the theory had no interest in building machines; they wanted to puzzle out the limits of reason in the absence of divine authority. If we could not rely on God or Aristotle to tell us how to think, could we instead build arguments that were self-contained and demonstrably correct? Can we be sure that mathematics is consistent? Are there things that are true but that cannot be expressed in language? 

The core ideas were worked out in the weekly meetings (Thursdays at 6) of a group remembered as the Vienna Circle. They got together in the office of Professor Moritz Schlick at the University of Vienna to discuss problems in philosophy, math, and language. The intersection of physics and philosophy had long been a specialty of this Vienna department, and this work had placed them among the world leaders.  Schlick’s colleague Hans Hahn was a central participant, and by 1928 Hahn brought along his graduate students Karl Menger and Kurt Gödel. Other frequent participants included philosopher Rudolf Carnap, psychologist Karl Popper, economist Ludwig von Mises (brought by his brother Frederick, a physicist),  graphic designer Otto Neurath (inventor of infographics), and architect Josef Frank (brought by his physicist brother, Phillip).  Out-of-town visitors often joined, including the young Johnny von Neumann, Alfred Tarski, and the irascible Ludwig Wittgenstein. 

When Schlick’s office grew too dim, participants adjourned to a nearby café for additional discussion with an even larger circle of participants.  This convivial circle was far from unique.  An intersecting circle–Neurath, von Mises, Oskar Morgenstern–established the Austrian School of free-market economics. There were theatrical circles (Peter Lorre, Hedy Lamarr, Max Reinhardt), and literary circles. The café was where things happened.

The interdisciplinarity of the group posed real challenges of temperament and understanding. Personalities were often a challenge. Gödel was convinced people were trying to poison him. Architect Josef Frank depended on contracts for public housing, which Mises opposed as wasteful. Wittgenstein’s temper had lost him his job as a secondary school teacher, and for some of these years he maintained a detailed list of whom he was willing to meet. Neurath was eager to detect muddled thinking and would interrupt a speaker with a shouted “Metaphysics!” The continuing amity of these meetings was facilitated by the personality of their leader, Moritz Schlick, who would be remembered as notably adept in keeping disagreements from becoming quarrels.

In the Café

The Viennese café of this era was long remembered as a particularly good place to argue with your friends, to read, and to write. Built to serve an imperial capital, the cafés found themselves with too much space and too few customers now that the Empire was gone. There was no need to turn tables: a café could only survive by coaxing customers to linger. Perhaps they would order another coffee, or one of their friends might drop by. One could play chess, or billiards, or read newspapers from abroad. Coffee was invariably served with a glass of purified spring water, still a novelty in an era in which most water was still unsafe to drink. That water glass would be refilled indefinitely. 

In the basement of one café, the poet Jura Soyfer staged “The End Of The World,” a musical comedy in which Professor Peep has discovered a comet heading for earth.

Prof. Peep: The comet is going to destroy everybody!

Hitler:  Destroying everybody is my business.

Of course, coffee can be prepared in many ways, and the Viennese café developed a broad vocabulary to represent precisely how one preferred to drink it: melange, Einspänner, Brauner, Schwarzer, Kapuziner. This extensive customization, with correspondingly esoteric conventions of service, established the café as a comfortable and personal third space, a neutral ground in which anyone who could afford a coffee would be welcome. Viennese of this era were fastidious in their use of personal titles, of which an abundance were in common use. Café waiters greeted regular customers with titles too, but were careful to address their patrons with titles a notch or two greater than they deserved. A graduate student would be Doktor, an unpaid postdoc Professor.  This assurance mattered all the more because so many members of the Circle (and so many other Viennese) came from elsewhere: Carnap from Wuppertal, Gödel from Brno, von Neumann from Budapest. No one was going to make fun of your clothes, mannerisms, or accent. Your friends wouldn’t be bothered by the pram in the hall. Everyone shared a Germanic Austrian literary and philosophical culture, not least those whose ancestors had been Eastern European Jews who knew that culture well, having read all about it in books.

The amiability of the café circle was enhanced by its openness. Because the circle sometimes extended to architects and actors, people could feel less constrained to admit shortfalls in their understanding. It was soon discovered that marble tabletops made a useful surface for pencil sketches, serving all as an improvised and accessible blackboard.

Comedies like “The End Of The World” and fictional newspaper sketches or feuilletons of writers like Joseph Roth and Stefan Zweig served as a second defense against disagreeable or churlish behavior. The knowledge that, if one got carried away, a parody of one’s remarks might shortly appear in Neue Freie Presse surely helped Professor Schlick keep matters in hand.

The End Of Red Vienna

Though Austria’s government drifted to the right after the War, Vienna’s city council had been Socialist, dedicated to public housing based on user-centered design, and embracing  ambitious programs of public outreach and adult education. In 1934 the Socialists lost a local election, and this era soon came to its end as the new administration focused on the imagined threat of the International Jewish Conspiracy. Most members of the Circle fled within months: von Neumann to Princeton, Neurath to Holland and Oxford, Popper to New Zealand, Carnap to Chicago. Prof. Schlick was murdered on the steps of the University by a student outraged by his former association with Jews.  Jura Soyfer, who wrote “The End Of The World,” died in Buchenwald.

In 1939, von Neumann finally convinced Gödel to accept a job in Princeton. Gödel was required to pay large fines to emigrate. The officer in charge of these fees would look back on this as the best posting of his career; his name was Eichmann.

Design for Amiability

An impressive literature recounts those discussions and the environment that facilitated the development of computing. How can we design for amiability?  This is not just a matter of choosing rounded typefaces and a cheerful pastel palette. I believe we may identify eight distinct issues that exert design forces in usefully amiable directions.

Seriousness: The Vienna Circle was wrestling with a notoriously difficult book—Wittgenstein’s Tractus Logico-Philosophicus—and a catalog of outstanding open questions in mathematics. They were concerned with consequential problems, not merely scoring points for debating. Constant reminders that the questions you are considering matter—not only that they are consequential or that those opposing you are scoundrels—help promote amity.

Empiricism: The characteristic approach of the Vienna Circle demanded that knowledge be grounded either in direct observation or in rigorous reasoning. Disagreement, when it arose, could be settled by observation or by proof. If neither seemed ready to hand, the matter could not be settled. On these terms, one can seldom if ever demolish an opposing argument, and trolling is pointless.

Abstraction: Disputes grow worse when losing the argument entails lost face or lost jobs. The Vienna Circle’s focus on theory—the limits of mathematics, the capability of language—promoted amity. Without seriousness, abstraction could have been merely academic, but the limits of reason and the consistency of mathematics were clearly serious.

Formality: The punctilious demeanor of waiters and the elaborated rituals of coffee service helped to establish orderly attitudes amongst the argumentative participants. This stands in contrast to the contemptuous sneer that now dominates social media.  

Schlamperei: Members of the Vienna Circle maintained a global correspondence, and they knew their work was at the frontier of research. Still, this was Vienna, at the margins of Europe: old-fashioned, frumpy, and dingy. Many participants came from even more obscure backwaters. Most or all harbored the suspicion that they were really schleppers, and a tinge of the ridiculous helped to moderate tempers. The director of “The End Of The World” had to pass the hat for money to purchase a moon for the set, and thought it was funny enough to write up for publication.

Openness: All sorts of people were involved in discussion, anyone might join in. Each week would bring different participants. Fluid borders reduce tension, and provide opportunities to broaden the range of discussion and the terms of engagement. Low entrance friction was characteristic of the café: anyone could come, and if you came twice you were virtually a regular. Permeable boundaries and café culture made it easier for moderating influences to draw in raconteurs and storytellers to defuse awkward moments, and Vienna’s cafés had no shortage of humorists. Openness counteracts the suspicion that promoters of amiability are exerting censorship.

Parody: The environs of the Circle—the university office and the café—were unmistakably public. There were writers about, some of them renowned humorists. The prospect that one’s bad taste or bad behavior might be ridiculed in print kept discussion within bounds. The sanction of public humiliation, however, was itself made mild by the veneer of fiction; even if you got a little carried away and a character based on you made a splash in some newspaper fiction, it wasn’t the end of the world.

Engagement: The subject matter was important to the participants, but it was esoteric: it did not matter very much to their mothers or their siblings. A small stumble or a minor humiliation could be shrugged off in ways that major media confrontations cannot.

I believe it is notable that this environment was designed to promote amiability through several different voices.  The café waiter flattered each newcomer and served everyone, and also kept out local pickpockets and drunks who would be mere disruptions. Schlick and other regulars kept discussion moving and on track. The fiction writers and raconteurs—perhaps the most peripheral of the participants—kept people in a good mood and reminded them that bad behavior could make anyone ridiculous.  Crucially, each of these voices were human: you could reason with them. Algorithmic or AI moderators, however clever, are seldom perceived as reasonable. The café circles had no central authority or Moderator against whom everyone’s resentments might be focused. Even after the disaster of 1934, what people remembered were those cheerful arguments.

I want to discuss accessibility because it is the most important thing for making websites. Other A List Apart articles give you innovation and insight. This article will give you homework. These are just my personal views, but they’re pretty good.

I want to start off with a couple of statements, and you will agree:

1. Designers are good people. I have never heard a designer say, “I don’t care if somebody can’t read this text”, “Not my fault if somebody can’t use this device”, or “Who cares if this is confusing?”
2. Some designs exclude people. You have seen people unable to read the text on a website or app that somebody designed. You’ve seen people unable to use a physical device that somebody has designed. You’ve seen people utterly bamboozled while trying to use a service that somebody designed.

So what?

The first question is, “Is this life-or-death stuff?” The answer is, “Yes.” In my favorite essay, This Is All There Is, Aral Balkan makes the point that pretty much everything that we design can affect life events and death events. Aral gives the example of how even a straightforward bus timetable app can affect life and death events, if we design it badly:

• somebody might miss a life event, such as their daughter’s fifth birthday party; or
• somebody might miss a death event, such as the chance to say goodbye to a dying grandmother.

The next—and frustrating—question is, “Why do some designs still exclude people?” After all, we know that:

• not everybody can see perfectly;
• not everybody can hear perfectly;
• not everybody thinks the same way; and
• not everybody moves the same way.

I think the answer is that there’s too much to recall. Consider, if you will, the wide variety of topics that A List Apart articles cover. Designers are expected to remember all of that guidance, plus all of the accessibility guidance, plus so much more. It is too much.

Recognizing accessibility issues while designing

I’d like to point toward one possible solution, starting from Jakob Nielsen’s 10 Usability Heuristics for User Interface Design. These are from the mid-1990s, and—although there’s a good chance that you, gentle reader, are a lot younger than that—please bear with me. 

Seeing as the problem is that there’s too much to recall, I want to look at heuristic № 6, “Recognition rather than Recall.” Jakob Nielsen said that for users, information required to use the design should be visible or easily retrievable when needed. I suggest we tweak that to make life easier for designers. Let’s say that the information required to produce the design should be visible or easily retrievable when needed. In other words, let’s make it easier to recognise accessibility issues while we’re designing.

How are we going to do that? I really like the book A Web for Everyone—Designing Accessible User Experiences by Sarah Horton and Whitney Quesenbery. I really like this book not only because it includes a quote from me—actually two quotes, but I don’t like to boast—but because it includes personas that are perfect for helping us to recognise accessibility issues. That’s the good news. The even better news is that these personas are available now for free on the companion website to the book What Every Engineer Should Know About Digital Accessibility, again by Sarah Horton, with David Sloan this time.

Meet your users

I’m going to introduce you to these personas now:

• Vishnu, an engineer and global citizen with low vision says, “I want to be on the same level as everyone else”, “If I can adjust my screen, I can read comfortably”, and, “Translating in my head is easier with simpler sentences.”
• Trevor, a high school student with autism, says, “I like consistent, familiar places on the web”, “When I can learn the pattern, I can find my way”, and, “Reading is hard for me”.
• Steven, a deaf graphic artist and American Sign Language speaker, says, “My only disability is that everyone doesn’t sign”, and, “Without captions, it’s meaningless to me”.
• Maria, a bilingual community health worker, says, “I love this. It’s all here … when I can find it”, “When a site is confusing, I just leave”—fair enough, Maria!—and, “When I hear and see it, health information makes more sense”.
• Lea, an editor living with fatigue and pain, says, “No one gets that this really is a disability”, “Don’t make me work so hard”—please do not bombard this lady with drop-down lists—and, “Links at the top of the page make navigation easier for me”.
• Jacob, a blind paralegal and a bit of a geek, says, “The right technology lets me do anything”, and “This makes it possible to do my job”.
• Emily, who has cerebral palsy and is living independently, says, “I want to do everything for myself”, “Simpler screens are easier screens”—hell yeah, Emily!—and, “Tell me what I need in advance”.
• Carol, a grandmother with macular degeneration which affects her sight, says, “My grandkids are dragging me into the world of technology”, “I don’t understand what the screen is saying”, and, “Why can’t the text be just a little bit larger?”

I want to throw one more persona at you now, because, well, A List Apart readers are overachievers. One of my favorite authors, Cennydd Bowles—who literally wrote the book on Future Ethics—says to create Personas Non Grata. In other words, every time we design something, we have to think about what a bad guy could do with that thing, and whom that might affect.

To actually use these personas while designing, I like what Eric Meyer and Sara Wachter-Boettcher in Design for Real Life call the Designated Dissenter: for each project that you work on, one of your teams should be responsible for asking, “Will this work for Vishnu?”, “How’s Trevor going to get on with this?”, and so on. 

Then, once you’ve used the personas to recognise the accessibility issues, you can look up the guidelines for whichever platforms you’re designing for: 

• Web Content Accessibility Guidelines (WCAG) 2.2
• Accessibility designing — Material Design 3
• Accessibility — Windows apps
• Accessibility | Apple Developer Documentation
• Check your interface for accessibility (Ubuntu)

Your mission, should you choose to accept it

I told you in the introduction of this article that I would give you homework. You thought I was joking. So, here’s your homework: I want you to grab the personas from the Know About Accessibility website, and use them throughout every design project to help you recognise accessibility issues while you work—and reclaim design for everyone.

NOTE: This article is based on “Recognise,” my five-minute presentation from Interaction Design Association (IxDA) Dublin’s Defuse (Design for Use) event in 2025.

Every language app in your pocket inherited a teaching method built for Latin. Understanding why that happened is a more useful design lesson than anything the apps themselves will teach you.

In 1788, Prussia introduced the Abitur, a standardized national examination required for entry into universities and the civil service. To pass it, students needed to demonstrate measurable, gradable knowledge. The system needed to teach language to large classrooms, produce consistent outcomes, and do it with one teacher and thirty students. The educators responsible for designing this system reached for the only teaching template they had, one that had been used in European schools for two centuries: the method developed to teach Latin.

Latin, by 1788, was a dead language. Nobody needed to speak it. The scholars who studied it were reading Cicero and Virgil, not conducting conversations. The method built around it, memorizing grammar rules, constructing translations, analyzing written texts, reflected that reality exactly. Oral skills were irrelevant. Comprehension of written form was everything. The method was not designed to produce speakers. It was designed to produce readers of texts in a language nobody spoke.

When Prussia applied this template to French and German, living languages spoken by living people, the premise did not change. Johann Valentin Meidinger’s textbook Praktische Französische Grammatik, published in 1804, ran to 37 editions across Europe by 1857. Karl Plotz formalized the approach into what became the dominant model for teaching modern languages across Europe and eventually the United States, where it became known simply as the Prussian Method [1]. Each institution that adopted it trained teachers in it, who trained students who became teachers. The constraint that created the method, how do you grade language at scale with limited resources, became invisible inside the method itself. What remained was the assumption: language is a body of rules to be learned consciously and measured. It was a design decision dressed up, over time, as a pedagogical truth.

The observation that should have ended it

There are people in the world who cannot read or write a language and speak it fluently. There are children who hold full conversations years before they can read a single word. There are immigrants who arrive in a country knowing nothing of its language and come out, years later, speaking it naturally, not because they studied it, but because they lived inside it. Literacy and fluency are separate things produced by entirely separate mechanisms. The Grammar-Translation method, as it became known, assumed they were the same thing. That assumption was inherited from a method designed for a language nobody needed to speak, and it was wrong the moment it was applied to a language people actually used.

The evidence against it accumulated slowly. In the mid to late nineteenth century, reformers including François Gouin in France and Maximilian Berlitz in the United States argued independently that language should be taught the way it is actually acquired, through immersive exposure to real communication in the target language, not through analysis of its rules. Berlitz built an entire school network around this principle. The reformers were correct. They were also largely ignored by mainstream education systems, because the Grammar-Translation method had one decisive advantage that direct immersion did not: it could be graded.

In 1982, the linguist Stephen Krashen gave the argument its most formal articulation in what he called the Monitor Model of second language acquisition. His distinction was precise: language acquisition, the unconscious process through which children absorb their native language and through which adults succeed in immersive environments, is categorically different from language learning, the conscious study of grammar rules and vocabulary that classrooms deliver [2]. Acquisition produces fluency. Learning, at best, produces the ability to pass a test. The evidence supporting this distinction, and the observation that immersive exposure to real native-speaker communication is the mechanism that produces genuine fluency, has only grown since.

I went to Brazil without a word of Portuguese and came out speaking it. I studied French in a classroom for years and cannot hold a conversation in French today. This is not an unusual experience. It is the expected outcome, and it has been the expected outcome for as long as we have had formal language education.

The same decision, made again in a different medium

Prussian educators faced the question: How do you deliver language learning at scale, measure progress, and retain users over time? The answer it arrived at was structurally identical to the one arrived at in 1788. Duolingo gamified the grammar drill into a streak. Anki formalized the translation exercise into a spaced-repetition flashcard. Babbel organized grammar lessons into structured modules. The interfaces were new. The underlying assumption, that language is a thing you study rather than an environment you inhabit, was not.

This was not a failure of design skill. The products that emerged from these decisions are, in many respects, genuinely well-crafted. Duolingo’s retention mechanics are sophisticated. Anki’s spaced repetition is grounded in real cognitive science. They are excellent at what they actually do. The problem is what they actually do: produce measurable engagement with a proxy for language rather than the conditions that produce language itself. A streak is measurable. A vocabulary score is measurable. The moment a user walks out of an app and holds a real conversation in another language, that happens in the world, outside the product, and cannot be instrumented.

When the outcome a user needs is difficult to measure directly, the design process tends to reach for something that can be measured. The proxy becomes the goal. The interface optimizes for it. The gap between what the product delivers and what the user actually needed grows. This is not a pattern unique to language learning. It is a pattern that repeats across product categories whenever a design constraint—the need to measure, the need to scale, the need to produce a grade—gets built into a system so deeply that it stops being visible as a constraint and starts being mistaken for a truth about the problem itself.

What happens when the constraint changes

The constraint that made the Grammar-Translation method necessary in 1788 was real and rational. One teacher. Thirty students. A standardized exam. You cannot grade a conversation at scale. You can grade a translation exercise. The method was not chosen because it produced fluency. It was chosen because it produced a score.

That constraint no longer exists in the same form. Technology has made it possible to deliver immersive, real-time conversation practice to anyone with a smartphone, at a cost that continues to fall. The design problem is no longer how to make language learning gradable at scale. It is how to make the conditions of genuine language acquisition accessible to people who cannot move to another country or afford a native-speaker tutor.

The products that are now closest to solving the actual problem are not the ones that invented a new pedagogy. They are the ones that removed the access barrier to an old one. Praktika builds AI conversation partners with distinct personalities, regional dialects, and cultural context, replicating the specificity of a real native speaker rather than a generic language-learning voice. Langua clones native speaker voices so that the interaction feels like a real conversation rather than a lesson. Rosetta Stone’s foundational methodology, image association in the target language with no translation, was built on the same insight Berlitz arrived at in the nineteenth century: language is acquired through immersive exposure, not through analysis of its rules [3]. A 2025 meta-analysis of 31 studies found that AI conversation tools produced a statistically significant improvement in language learning outcomes, a result that no amount of flashcard optimization has consistently matched [4].

None of these products invented a new theory of language acquisition. They translated an existing one into something more people could reach.

The design question this leaves

The Grammar-Translation method persisted not because educators were wrong about design, but because a design decision made under a specific constraint became, over two centuries, indistinguishable from the thing itself. The constraint, how do you grade language at scale, was forgotten. The method it produced was inherited as if it were a description of how language works, passed from Prussia to Europe to America to the App Store, from the grammar drill to the streak.

Every time a design team optimizes for a metric because the actual outcome is hard to measure, they are making a version of the same decision. It is often the right decision given real constraints. The question worth asking is whether the constraint that made it necessary still exists, or whether it has simply become invisible inside the system it originally produced.

Before reaching for what can be measured, it is worth asking what the user actually needs to do, and what stopped them from doing it before. Sometimes the answer is a new solution. More often it is an old one that was always out of reach.
