UI/UX Design: The Key to Excellent Design
Times are tough, that’s a fact. We live in a world where the pace of change is constantly increasing, and user expectations are getting higher. They demand that products and services not only be fast and functional but also intuitive and aesthetic. This is where User Interface (UI) and User Experience (UX) design play a key role. Understanding and properly implementing them can significantly impact the success of any application, website, or product.

What are UX and UI Design?
Imagine you’re visiting your bank’s website to make a quick transfer. You expect everything to go smoothly. But instead of an intuitive interface, the site is chaotic, buttons are poorly arranged, and the transfer process takes much longer than it should. After a few minutes of frustration, you give up and decide to try again later – or worse, you look for another service that better meets your needs. This is where the power of good or bad UX/UI design is evident. A well-designed interface and a smooth user journey can ensure that not only will the customer achieve their goal, but they’ll also be eager to return.
UI and UX are two complementary disciplines that together create the user experience. While UI focuses on the visual and interactive side of the product, UX encompasses a broad range of actions aimed at understanding user needs and designing appropriate solutions.
What is UX Design?
UX Design is a process focused on the user experience. It’s about ensuring that a product not only serves its purpose but is also intuitive, efficient, and satisfying to use. UX designers analyze how users interact with the product, what their needs, problems, and goals are. As a result, they design solutions that maximize positive user experiences.
UX is unique in that an average user only notices it when it’s bad. A well-designed user experience should be invisible, allowing users to perform tasks without having to learn how to use the system. Only then can we speak of a good user experience. It’s the outcome of research, analysis, the designers’ expertise, and generally accepted norms in the world around us. A great example to easily understand what UX is comes from Don Norman’s book “The Design of Everyday Things.” We’ve all, at least once, pulled a door that says "push." This is an example of an interaction that requires learning the system’s operation due to poorly designed UI. The ability to adjust a design (in this case, the door) to meet a need (entering/exiting the room) while allowing the user to interact (opening the door) and achieving the intended goal (entering the room), considering system limitations (for example, the door can only open one way), is a key task of the user experience designer.

UX Laws
In UX design, there are several laws that help understand how users interact with products. Jon Yablonski, in his book "UX Laws," describes key principles that support the process of creating user-friendly interfaces. Here are three of them:
- Jakob's Law
"Users tend to prefer interfaces that work similarly to those they are already familiar with." This law highlights that users have strong habits based on their previous experiences with other products. Therefore, UX designers need to create solutions that are intuitive and understandable, referencing familiar patterns.
- Hick's Law
"The time it takes to make a decision increases with the number and complexity of options." The more choices you offer users, the harder it becomes for them to make a decision. Therefore, UX designers should aim to simplify interfaces and minimize the number of choices users have to make to quickly and efficiently achieve their goals.
- Miller's Law
"People can hold approximately seven items (+/- 2) in their short-term memory." This law refers to the limits of human perception and memory. UX designers must ensure not to overwhelm users with too much information at once, aiming to limit the number of options displayed to around seven items.
Each of these laws aims to improve usability and the user experience, helping designers create more effective and user-friendly interfaces.

UX Design Example
Imagine you have a food delivery app. If the UX was poorly designed, it could mean a complicated ordering process, where it’s hard to find your favorite restaurants, and navigating between the cart and the menu is cumbersome. Bad UX will cause users to quickly become frustrated, potentially leading them to never use the app again. On the other hand, good UX means intuitive ordering steps – quick access to the menu, recommendations based on previous orders, and a simple payment process. This creates a pleasant user experience, increasing the chances that users will return and use the app again.
What is UI Design?
UI Design is the process of designing the user interface, which includes the appearance, layout, and interactions that users directly engage with. This involves everything we see on the screen – buttons, icons, typography, colors, and element arrangements. UI designers aim to make the interface aesthetically pleasing, functional, and aligned with user expectations.
UI Design Example
Think of a music streaming app, like Spotify. The UI designer is responsible for ensuring that every function, such as the "play" and "pause" buttons, song lists, and album covers, are clear and easy to interact with. A good example of UI design is harmoniously chosen colors that don’t strain the eyes, well-placed buttons that are easy to click, and visible typography that enables quick understanding of available features. As a result, users not only enjoy using the app but also quickly find all the necessary features. Even if the user has the screen brightness reduced to a minimum, a well-designed UI allows them to navigate intuitively without guessing where things are. Such details make using the app seamless, regardless of the environment.
Differences and Collaboration Between UX and UI
While UX design and UI design often go hand in hand, they are two distinct fields. UX design focuses on the user's experience, while UI design focuses on visual interaction. UX design can encompass the entire user journey, from the moment they land on a website to the completion of the interaction, while UI design focuses on how the user "sees" and "touches" the product.
How UX and UI Work Together
UX and UI departments work closely to create a comprehensive and consistent user experience. A UX designer is responsible for designing the user experience, determining how the product should function, what features are essential, and how the user should navigate through the application. This is where user flow design and interaction design come into play, which are crucial for ease of use.
Then, the UI designer translates these assumptions into a visual interface that the user sees on the screen and interacts with. The collaboration between UX and UI goes beyond design – it also includes joint research and analysis that help deliver smooth, enjoyable, and effective user experiences. Thanks to this collaboration, the product not only works well but also looks attractive and is easy to use.
What Does a UX Designer Do? What is the Difference Between a UX and UI Designer?
- UX Designer: Focuses on designing user experiences and researching how to best meet user needs. They conduct user research, create user personas, and prototype solutions. Their task is to ensure that the product meets user expectations in terms of functionality and efficiency. A key element of a UX designer's work is analyzing usability test results, which help optimize the process.
- UI Designer: Their main role is to design the visual interface and web pages. They are responsible for choosing colors, typography, layout, and ensuring visual consistency throughout the product. They also focus on usability, ensuring that each feature is easily accessible and intuitive. A UI designer pays attention to details to ensure that digital products are not only aesthetically pleasing but also functional.
When Should You Implement the User Experience Design Process?
UX Design is based on user research and understanding their needs. UX design is a multi-step process that requires precise planning and testing at various stages.
User Research: The Key to Success
User research is the first and most important step in the UX process. It allows for a better understanding of who the users are, what their needs and expectations are. At this stage, UX designers gather data using interviews, surveys, or behavioral analysis.
Creating User Personas
User personas are detailed profiles of typical product users that help the team understand for whom the solution is being designed. Personas include information about goals, preferences, problems, and user expectations.
Designing User Flow
User flow maps show how users move through a product, from entry to goal completion. This allows UX designers to plan intuitive and smooth interaction paths.
Wireframing and Prototyping
Wireframing involves creating rough sketches of the product's structure, showing the layout of elements without visual details. Prototyping, on the other hand, involves creating more detailed models that allow testing the product's functionality before final implementation.
Conducting Usability Testing
Usability testing is the stage where it is checked how users actually interact with the product. This helps identify errors, problems, and areas for improvement before the final implementation.
UI Design Process
While UX focuses on the user experience, UI design is responsible for creating the product's visual and interactive layer.
UI Patterns and Information Architecture
UI patterns are proven interaction patterns that help users navigate the product. Information architecture, on the other hand, is about how information is organized and presented to the user to make it easily accessible and understandable.
Website Responsiveness: Adapting to Devices
Responsiveness is a key aspect of UI design since users access products from various devices – computers, tablets, and smartphones. UI designers must ensure that the interface looks and works well on every device.
Improving Accessibility and Usability
Accessibility is a crucial aspect of design that allows products to meet the needs of various user groups, including people with disabilities. UI/UX designers should consider accessibility to ensure that the product is available and easy to use for everyone.
Example: Apple and the Power of Simplicity
One of the best examples of a company successfully applying UI and UX principles is Apple. Its products are valued worldwide not only for their functionality but also for their excellent user interfaces. Apple consistently emphasizes minimalism, intuitiveness, and aesthetics, making using their devices enjoyable and seamless.
