User experience (UX): the key to optimising digital interaction

Deep Dive


In an increasingly digitalised world, user experience (UX) is no longer just a "nice extra", but has long since become a strategic success factor. After all, the way in which people use and perceive digital products and services is constantly changing. Companies need to adapt to this rapid development if they want to reach and successfully engage with their customers in the future.

User experience promotes business success

The importance of UX lies in its ability to shape and optimise the way in which customers experience digital interactions. At its core, it is about how pleasantly, efficiently and effectively users can interact with a digital platform or application. A positive user experience contributes significantly to customer loyalty, increases satisfaction and ultimately promotes business success. But user experience goes far beyond mere customer friendliness - it also influences the efficiency of internal processes and the productivity of employees.

User experience potentially offers companies the following advantages, among others:

Customer loyalty

Satisfied customers remain loyal and recommend products or services to others.

Cost savings

A good user experience can reduce the number of support requests and increase the efficiency of processes.


Close collaboration with users in the design of the user experience can lead to innovative ideas and new product developments.

Brand image

A positive user experience strengthens the brand image and customer trust.

What is user experience (UX)?

By user experience (UX), we mean the totality of all impressions and emotions that users experience when interacting with a digital platform, an application or a product. It is about the way in which they perceive the user-friendliness, design, efficiency and effectiveness of a digital product or service. Overall, the user experience is the decisive factor that determines whether users love a digital solution and use it again and again or give up in frustration.

The core components of the user experience (UX) are:

A product or application must offer a clear benefit and fulfil the needs of the user.


The platform should be simple and intuitive to use, without unnecessary complexity or confusion.


The visual design and layout should be appealing and reflect the brand image.


Ultimately, the interaction should be positive and enjoyable in order to satisfy the customer.

The difference between user experience (UX) and user interface (UI)

Although user experience and user interface are closely related, they are not the same thing. The user interface (UI) refers to the concrete interface that users use to interact with an application or product. The focus here is on visual elements such as buttons, menus and icons. The user interface is therefore definitely a part of the user experience, but not the entire experience. 

User experience, on the other hand, goes far beyond visual design and encompasses all aspects of interaction, including the arrangement of elements, navigation, performance and overall satisfaction. An appealing user interface is important, but without a well-thought-out user experience, even the most appealing design cannot optimise the user experience.

Why is user experience important?

Investing in a first-class user experience is an investment in business success. Companies that recognise its importance and work on it consistently will be rewarded in the long term.

The importance of user experience
The users take centre stage

An outstanding user experience ensures that the needs, expectations and preferences of customers are understood and fulfilled. It stands for a customer-centred mindset.

Positive emotions and customer loyalty

A good user experience generates positive emotions among users. They feel valued and understood, which leads to greater customer loyalty. Loyalty is a valuable asset as it promotes repeat business and positive word of mouth.

Competitive advantage

In a highly competitive market environment, a superior user experience can set companies apart from the competition. Customers often choose products or services based on their user-friendliness and experience.

The effects of good and bad user experience

Providing users with a smooth and enjoyable experience with a product or platform can lead to various positive business outcomes:

Increase in sales

Satisfied customers are more willing to spend more money and make use of additional services.

Customer loyalty

They return more frequently and remain customers in the long term.

Good brand image

A positive user experience strengthens the brand image and can lead to positive word of mouth.

On the other hand, a poor user experience can have an extremely negative impact on business success:
Loss of revenue

Customers leave the platform in frustration due to the poor user experience and shop elsewhere.

schlechtes image
Poor brand image

Negative experiences can damage a brand's reputation and have a lasting negative impact on the customer relationship.

Higher support costs

A poor user experience often leads to an increase in support requests and therefore to higher customer service costs.

User interface design: building a bridge to the user experience

User interface design (UI design) is a central component of the user experience (UX) through which users interact with digital products and services. It is the visual and interactive design that largely determines how user-friendly and appealing an application or platform is perceived.

Basics of interface design 

The basics of UI design include visual components such as layouts, colour schemes, fonts, images and icons. At the same time, UI design includes interaction elements such as buttons, menus and forms. These visual and interactive elements are crucial for the user experience, as they have a significant influence on usability and aesthetics.

Best practices in user interface design

To ensure a first-class user experience, the following best practices should be observed in UI design:

Clarity and consistency

Standardised layouts, symbols and navigation elements create familiarity and make it easier for users to find their way around.


The design should be tailored to the needs and expectations of the target group.

Responsive design

The interface should adapt to different screen sizes and devices to ensure a consistent experience.


The design should be accessible to all users, including people with disabilities.


Fast loading times and smooth interactions are crucial for a positive user experience.

The importance of responsive design

Responsive design is a key component in UI design. It enables digital platforms or applications to function and display optimally on different end devices - from desktop computers to tablets and smartphones. This ensures a consistent user experience on all devices.

Digital transformation and user experience

The topics of digital transformation and user experience are inextricably linked. While digital transformation paves the way for innovative solutions, user experience is the key to successful implementation and achieving strategic goals. Companies that skilfully combine these two aspects are ideally positioned to succeed in the digital age. 

The role of user experience in digital transformation
The importance of prototyping

Prototyping is a crucial step in the early phase of the design process to visualise ideas, test interactions and point out potential problems at an early stage. Through prototyping, companies can ensure that subsequent development and implementation is based on a solid foundation and fulfils user expectations.

Fulfilment of customer expectations

In an increasingly digitalised world, customers expect seamless and user-friendly digital interactions. A first-class user experience fulfils these expectations and helps to attract and retain customers.

Increased efficiency

A well-designed user experience can optimise internal processes and increase productivity. This enables companies to utilise resources more efficiently.


Companies that offer an outstanding user experience are able to stand out in a highly competitive market. A convincing user experience can become a decisive competitive advantage.
