UX design can seem daunting for beginners, especially if you don't know where to start. We've compiled key recommendations from renowned international experts Jakob Nielsen, Ben Shneiderman, and Bruce Tognazzini, as well as our experts Vlad Golovach and Ilya Birman. These tips will help aspiring designers, planners, UX writers, and product managers create high-quality, intuitive, and engaging digital products. By following these principles, you can improve the user experience, increase customer satisfaction, and achieve successful results in your projects.

Principle 1 is that each element of the system should perform its function efficiently and cost-effectively. This means optimizing processes, avoiding redundancy and simplifying interactions between components. Effective resource allocation and a clear understanding of the roles of each element contribute to increased overall productivity and minimized errors. This approach allows you to achieve maximum results with minimal investment of time and effort, which is key to the successful functioning of the system.

Based on the needs of real users, not on your own assumptions

A design may look impressive, but it loses its value if it does not consider the needs and interests of the product's target audience. It is important to develop a design that not only attracts attention but also meets user expectations, providing convenience and functionality. The right design approach will help create a deeper connection with the audience and improve the effectiveness of the product. UX design, or user experience design, focuses the designer's attention on how users interact with the product. It's important to evaluate how convenient and intuitive the product is for the target audience. Effective UX design improves the user experience, contributes to increased customer satisfaction, and ultimately contributes to the product's success in the marketplace. Analyzing user needs and testing interactions with a product help to identify its strengths and weaknesses, which allows you to create a more attractive and functional interface.

Principle 2 emphasizes the importance of maintaining consistency and logic in the task process. This not only improves work efficiency but also the quality of the final result. This principle helps avoid errors and misunderstandings and fosters a clearer understanding of goals. A consistent approach helps organize the workflow and minimize the risk of wasted time. By adhering to this principle, you can achieve the best results and significantly increase productivity.

Explain what's happening

It's important for users to have a clear understanding of the consequences of their actions and to be able to anticipate the results in advance. This relieves them of stress and uncertainty. Confidence in the security of data plays a key role in building trust in the service. Jakob Nielsen emphasizes that predictability in working with a service directly affects the level of user trust and improves the overall experience of interacting with the product.

In his book "User Interface," Ilya Birman emphasizes the importance of feedback in user interface design. He notes that users should receive clear and timely notifications about their actions. This helps build trust in the interface and improves the overall user experience. Feedback can take various forms, such as visual effects, sound cues, or text messages. It is important that such information is intuitive and meets user expectations, which in turn facilitates more effective interaction with the product. Effective feedback not only increases user satisfaction but also contributes to business goals, as users are more likely to return to a product that provides clear and useful notifications.

At Chelyabinsk Post Office No. 80, an electronic queue has been implemented, making it more convenient to wait for service. A special machine with a single button has been installed at the entrance. When you press the button, a receipt number appears on the receipt tape after two seconds. These two seconds seem long, and many users press the button again without seeing a result. As a result, "extra" receipt numbers often end up near the machine. If the machine responded to the button press, for example, with a beep or a flashing light, this would help avoid confusion and improve the user experience. Implementing such simple solutions could significantly improve the efficiency of the post office and simplify the customer service process.

Bruce Tognazzini emphasizes the importance of an intuitive interface, noting, "Users shouldn't waste time searching or guessing about the system's state. They should simply glance at the interface and instantly understand the current state." This approach to interface design contributes to an improved user experience and increased efficiency in interacting with the system.

Feedback plays a key role in the interaction process. It helps to better understand user needs and expectations. Regularly receiving feedback allows you to improve the quality of services and products, as well as increase customer satisfaction. Don't miss the opportunity to establish a dialogue with your audience, as this contributes to the development and successful growth of your business. Your feedback is important to us, so we are always ready to listen to it.

Principle 3 is that effective interaction with customers is based on understanding their needs and expectations. It is important not only to provide high-quality products or services, but also to actively listen to customers, taking into account their opinions and comments. This allows you not only to improve current offerings but also to develop new solutions that will meet the needs of the target audience. Business success directly depends on the ability to adapt to changes in consumer preferences and respond quickly to them. Implementing this principle helps build customer trust and loyalty.

Make the product interface similar to similar ones

There's no point in reinventing the wheel when you can use proven patterns. At first glance, it may seem like there's no creativity here. However, this is not the case: first and foremost, it's about user comfort. Using familiar and convenient patterns improves the user experience and allows you to focus on the quality of the content. Caring for users should always be a priority, and using old but reliable solutions is one way to ensure their satisfaction.

The product interface should be intuitive so users can quickly start using it. The more familiar and simple the interface is, the less time they will need to learn. This is especially important, as not all users are willing to invest a lot of time in mastering new technologies. Ben Schneiderman and Jakob Nielsen emphasize that initial simplicity and interface consistency significantly improve the user experience. Creating a user-friendly and intuitive interface promotes faster user engagement and increases their satisfaction.

Bruce Tognazzini emphasizes that fashion and beauty should not trump usability. It's important that aesthetics not interfere with functionality. User experience must remain a priority, even in the face of modern design trends. The balance between visual appeal and usability is key to a successful product.

Principle 4 is a key aspect that must be considered to achieve successful results. It covers important elements that affect the efficiency of processes. Compliance with this principle contributes to improved work quality and increased productivity.

Implementing this principle helps optimize resources, minimize costs, and improve team collaboration. Its application can significantly accelerate the achievement of goals and increase the overall level of customer satisfaction.

By following this principle, organizations can strengthen their position in the market, ensuring competitiveness and sustainable growth. It is important to remember that consistent adherence to this principle is the key to long-term success.

Prevent Errors

In the book "User Interface Design", Vlad Golovach emphasizes the importance of error messages. He emphasizes that clear and understandable notifications help users quickly navigate issues that arise while using the interface. Effective error messages not only inform users of the problem but also offer possible solutions, significantly improving the user experience. Golovach also notes that error design should be intuitive and consistent with the overall interface style so users can easily perceive the information and take appropriate action. Effective error messages build trust in the product and improve overall user satisfaction.

Most error messages are not actually true errors. These notifications provide information to the user about the state of the system they are using. They can indicate connection issues, incorrect data, or lack of necessary access rights. Rather than viewing them as a negative experience, users should view these messages as tips for resolving issues and improving their interaction with the system. Proper understanding of such notifications can significantly improve the overall effectiveness of working with software and reduce stress levels when unexpected situations arise.

• is not flexible enough to adapt to the user's actions;
• is not smart enough to show the user the possible limits of his actions;
• is overconfident and believes that the user is a fool who can and should be bossed around.

All leading usability experts agree that it is more effective not only to provide high-quality error notifications, but also to prevent them from occurring. Error prevention improves the user experience and reduces the number of negative interactions with the interface. Tools and techniques that minimize errors help create more intuitive and user-friendly apps and websites, which in turn increases user satisfaction and loyalty.

There are two main types of errors: misses and errors. Misses are random deviations from the correct result, which can occur due to lack of information or random factors. Errors, on the other hand, are systematic deviations that arise from misunderstandings, incorrect assumptions, or flaws in methods. Understanding these types of errors is important for improving processes and improving the quality of work in various fields.

• Mistakes are careless errors.
• Errors are deliberate actions that occur because the user did not understand the service or the design was not clear enough.

To avoid user errors, it is important to set constraints on actions and set appropriate default values. It is also necessary to identify areas in the interface where unwanted actions can occur due to inattention. For example, to ensure that the user can easily click the "Save" button, the "Delete" or "Exit without saving" button should be placed at a sufficient distance from it. This will improve usability and reduce the likelihood of accidental errors.

Avoid errors by providing users with the necessary information at each step. Ensure that users do not have to remember the sequence of actions, and provide the ability to quickly undo actions. This will improve usability and reduce the number of errors.

If an error cannot be prevented, it is important to provide the user with a clear and understandable error message. Jakob Nielsen, a respected usability expert, emphasizes the need for clarity in such situations. The message should be informative and include recommendations for correcting the problem so that the user can quickly understand what happened and how to fix it. This not only improves the user experience but also helps build trust in the resource.

• Explain what went wrong in the language of your audience. Avoid technical jargon.
• Offer a solution that can immediately resolve the error or provide some other assistance.

Principle 5 emphasizes the importance of consistency in actions and decision-making. This principle is based on the fact that to achieve goals, it is necessary to follow a clear strategy and adhere to the planned approach. Consistency helps avoid errors and misunderstandings and promotes more efficient use of resources. When implementing this principle, it is important to consider all aspects affecting the process and adapt to changing conditions. By following the principle of consistency, you can achieve consistent results and successful task completion.

Reduce information load

It is important to provide complete product information so that users can easily understand and make an informed decision. Instead of cluttering the site with redundant information, it is better to organize the content so that it is clear and accessible. This will help potential buyers get a clear idea of ​​the benefits and characteristics of the product and facilitate the selection process. Well-designed content not only improves the user experience but also contributes to higher rankings in search engines.

Jakob Nielsen argues that the key to effectiveness lies not in the amount of information presented, but in the ability to provide the right data at the right time. This approach helps reduce cognitive load, allowing users to perceive information step by step and in a logical order. People prefer structured content, which makes it easier to perceive and assimilate. Proper distribution of information facilitates better understanding and improves user experience.

Each piece of information added to the interface competes with other information, reducing its visibility and creating additional noise. This negatively impacts the overall perception of the page. Optimizing content and simplifying the interface will help improve the user experience and make information more accessible.

Reducing the amount of information on landing pages and mobile apps is not mandatory. It is important to identify key user needs and problems and focus on them. Remaining information should support and confirm the main ideas, presented to the user in a step-by-step manner. This will allow you to create a more effective and understandable interface that will meet the needs of the target audience and contribute to an improved user experience.

Thanks to this principle, Google Help remains a relevant and attractive resource that does not turn into a simple reference book that loses interest among users. This platform continues to attract attention thanks to its interactivity and accessibility of information, making it an indispensable tool for finding answers to questions.

Principle 6 is the importance of balancing content quality and quantity. Creating unique and valuable content helps attract your target audience and increase search engine visibility. However, it's important to remember that regularly updating and adding new material also plays a key role in maintaining user interest and improving website rankings. Using relevant keywords and phrases in the text helps optimize for SEO, which makes your content more visible to search engines. Constantly focusing on the quality and relevance of the information on your website will help you build trust with visitors and ensure long-term success.

Design for everyone's convenience

About 15% of the world's population, or approximately one billion people, live with a disability. Research shows that 70% of users with disabilities abandon a website if it doesn't meet their needs. This underscores the importance of web accessibility, as ignoring this audience means losing a significant number of potential visitors and customers. Ensuring website accessibility not only improves the user experience but also expands the reach of your audience, a key aspect of a successful online presence.

Ben Schneiderman and Jakob Nielsen emphasize the importance of considering the needs and limitations of the target audience when designing. It's also important to consider the differences between novice and experienced users: the former should include explanatory tooltips, while the latter should utilize complex functions and keyboard shortcuts. It's important to consider the age, disability, cultural background, and devices of users. This approach helps create an inclusive and user-friendly interface, which in turn improves the user experience and increases audience satisfaction.

Use contrasting colors for text in your layout. This significantly improves readability for visually impaired users and in low-light conditions. Using contrasting colors makes content more accessible and comfortable to read. For example, the Slack platform effectively uses this technique, ensuring ease of reading and interaction with information. The correct choice of color scheme contributes to better perception of text and reduces eye strain, which is especially important in modern design.

To understand what is really convenient for users, it is necessary to conduct testing. This will help you identify your audience's preferences and needs, as well as evaluate the usability of the interface and functionality. Regular testing will help improve the user experience, increase customer satisfaction, and, as a result, increase conversions. Use A/B testing and surveys to collect data to help you make informed decisions. Remember, listening to user feedback is key to creating an effective product.

During UX testing, users actively interact with the product while a researcher monitors their actions and identifies any difficulties they encounter. If a group of users experiences similar issues, this serves as a signal for design changes. Improving the user experience depends on identifying and fixing problems like these, which leads to a more intuitive and effective product.

Principle 7 is a key aspect that contributes to the successful implementation of various projects and initiatives. It implies the need to adhere to certain standards and methods, which allows for high results. It is important to understand that this principle not only promotes effective management but also improves interaction between process participants.

It should be noted that the application of Principle 7 can significantly improve the quality of decisions made and speed up task completion. Moreover, its implementation contributes to the creation of a more transparent and understandable structure, which in turn increases the level of trust among all stakeholders.

The implementation of this principle requires a systematic approach and continuous monitoring, which will allow for prompt changes and adjustments. This makes the process more flexible and adaptive to changes in the external environment. Thus, Principle 7 is integral to successful project management and achieving goals.

Don't make users remember too much information

Information necessary for effective use of the service, such as field labels or menu items, should be clearly visible or easily accessible. To achieve this goal, it is important to provide an intuitive interface that allows users to quickly find the information they need. Optimizing navigation and structuring content will help improve the user experience and reduce the time spent searching for information. Placing important elements prominently and using clear labels also helps improve the overall user experience.

• Offer help right there, in context, instead of training users' memory;

• Reduce the amount of information you need to remember. Most people find it easier to recognize a suggested answer than to recall the correct one. You're more likely to get the correct answer to "Is Phnom Penh the capital of Cambodia?" than to "What is the capital of Cambodia?"

Jakob Nielsen aptly observed, "Recognition is better than recall." This idea underscores the importance of design and user experience, where ease of navigation and an intuitive interface play a key role. Effective use of visual cues and familiar elements helps users find the information they need faster, which increases overall satisfaction with the website or app. Optimizing content with recognition in mind can significantly improve comprehension and facilitate the search process, which in turn contributes to higher conversion and user retention.

The user is constantly in a situation where they can accidentally corrupt data or the system. For example, they might format a hard drive or delete an important file. This naturally leads to a fear of errors. Therefore, it's important to create conditions where users can be confident that nothing critical will happen without their consent. Safe technologies and clear interfaces will help reduce anxiety and increase trust in the system.
