When the mockup comes before the brief
This is a familiar scenario: a client arrives with ready-made mockups, perhaps created in-house or with accessible design tools, expecting our role to be simply “making it real.” That expectation is understandable. In an era where digital tools are widely democratized, almost anyone can create a visually appealing layout. However, there is a fundamental difference between drawing an interface and designing a user experience. The issue is not the client’s proactivity or enthusiasm. The real problem arises when these proposals ignore core UX principles and established UI design patterns. Accepting such solutions without questioning them means failing in our role: translating business goals and user needs into digital solutions that are effective, usable, and accessible.
The endless revision loop
Things become even more complex when projects fall into an endless revision loop, where feedback is driven by subjective impressions rather than objective criteria. “This green doesn’t convince me”, “I’d rather have the call-to-action on the left” or “Let’s make the text bigger”: behind each request there is often a legitimate perception, but rarely an understanding of the implications that change will have on information architecture, visual hierarchy, or overall usability.
Designers are then faced with a choice: comply with requests that contradict established principles, or justify every design decision—risking being perceived as rigid or uncooperative. This is exactly where the value of the designer emerges. Our role is to mediate between client requests and design principles, turning feedback into an opportunity for dialogue. The goal is not to reject ideas, but to explain the impact of each choice and propose solutions that respect both the client’s vision and the needs of end users.
The AI illusion: design for everyone?
With the rise of generative AI, this perception has intensified even further. Today, anyone can ask an AI to “create a modern interface for an e-commerce website” and receive a visually appealing result in seconds. But again, the tool does not replace expertise.
AI can generate endless variations, but it does not know which usability principles to apply. It lacks an understanding of the project’s specific context, cannot run tests with real users, and cannot interpret user needs. It can generate shapes, but it cannot ensure those shapes support concrete business goals or deliver a seamless user experience. The real risk is confusing execution speed with design quality. AI is a powerful tool in the hands of an experienced designer—but it remains a tool. Methodology, strategic vision, and the ability to balance competing needs are still irreplaceable human skills.
UX Design: much more than “User Experience”
When we talk about UX design, we are not referring to an abstract concept. UX is a discipline with solid scientific foundations rooted in cognitive psychology, ergonomics, and design thinking.
There are universally recognized principles that guide the creation of effective interfaces. Take Nielsen’s Heuristics (Jakob Nielsen, a pioneer of usability): these are not suggestions, but standards shaped by decades of research and real-user testing.
Some concrete examples:
- Hick’s Law: the more options you present to users, the longer it takes them to make a decision. Overloading a homepage with ten different calls to action doesn’t offer more choice, it creates paralysis.
- Fitts's Law: the size and distance of an interactive element directly affect how easily users can click it. Placing a critical button in a remote corner of the screen compromises usability, regardless of visual preference.
- Jakob's Law: users expect your site to work like other sites they already know. Breaking established patterns, such as navigation menus or shopping cart placement in e-commerce, is not innovation; it creates friction.
When a client says, “I would do it this way,” they are expressing the perspective of a single individual, often deeply involved in the product and digitally skilled. But what about the end user? The person using the software for the first time, perhaps with limited digital literacy and very different expectations? That user—not the stakeholder’s preference—must guide design decisions.
UI Design: where form follows function
If UX defines the what and the why, UI design defines the how—visually. And here too, rules apply, deeply rooted in the history of typography and visual communication.
From Gutenberg to digital design
Many principles of modern design are the result of centuries of evolution. The Gutenberg Diagram describes how Western readers naturally scan a page: from the top-left corner, through the center, to the bottom-right. Knowledge developed over 600 years ago still shapes how we structure digital interfaces today.
Modular grids, developed by Swiss designers like Josef Müller-Brockmann in the 1950s, form the backbone of modern responsive layouts. Proportions studied since classical antiquity continue to influence spacing and sizing decisions.
Design did not begin with Figma or Sketch. It is a discipline built on centuries of research, experimentation, and refinement.
Design Systems and visual consistency
In digital products, a design system is not a stylistic exerciseit is a fundamental tool for consistency, scalability, and maintainability.
Defining reusable components, interaction patterns, spacing systems, and typographic scales creates a shared visual language that:
- Reduces users’ cognitive load, as they don’t have to relearn how each page works.
- Speeds up development through reusable components.
- Simplifies maintenance.
- Ensures accessibility standards are applied consistently.
Trust the process (and the Designer)
So, what real value does a professional designer bring to a project? Our role is to act as a bridge between business goals and user needs, using proven methods and established principles to find the optimal balance. When a client proposes a solution based solely on personal taste or experience, they often lack:
- Methodology: tools to validate intuition with real data.
- Knowledge of standards: awareness of established patterns and best practices.
- User perspective: the ability to step outside their own point of view.
A professional designer brings exactly these elements, not to impose a vision, but to transform insights and objectives into solutions that truly work for the people who will use them.
At the same time, we ask for recognition that behind every design choice there is a method, not a personal preference.
When you trust a designer, you are investing in:
- The application of scientifically validated principles.
- Knowledge of accessibility and usability standards.
- The ability to balance functionality with business objectives.
- Experience in preventing costly errors that are difficult to fix later.
Personal taste still has its place: in choosing a color palette that reflects brand identity, defining tone of voice, or shaping the overall atmosphere of a product. But the foundations, the structure, logic, and experience architecture, must follow established rules and always put the end user at the center.
