What is UX Design — Definition, Methods, and Impact for Companies
UX Design, also known as UX, refers to the human-centered design of products and services with the goal of creating a desirable experience during use. The discipline combines user understanding, business goals, and concrete product solutions. Its roots lie in Human-Centered Design: identifying people's problems and designing suitable solutions that are desirable, technically feasible, and economically viable. UX Design encompasses sub-disciplines such as Design Strategy, User Research, Interaction Design, and User Interface Design.
What is UX Design?
(Definition and Origin)
UX Design stands for User Experience Design — the design of the user experience when interacting with a product or service. The term shifts the focus from the object to the experience: it's not the artifact itself that is central, but what people experience when using it.
The roots of UX Design lie in Human-Centered Design. Designers identify real problems of people and design suitable solutions — solutions that are desirable first, before being technically and economically evaluated. This approach, which starts with the need rather than the technology, continues to shape the discipline today.
The end result is the User Experience that users experience when interacting with the User Interface. UX Design ensures that products function logically, users quickly achieve their goals, and complex processes become easy to use. UX Design is an umbrella term that encompasses sub-disciplines such as Design Strategy, User Research, Interaction Design, and User Interface Design. How UX Design differentiates from related terms like Customer Experience and Usability is clarified in the Glossary.
Why UX Design affects every product
Every product has a user experience — whether consciously designed or not. The question is not whether UX exists, but whether it is actively designed.
If a product solves a major problem and thus creates high value, users are more likely to accept an experience associated with hurdles. But as soon as comparable solutions are on the market, the user experience makes the difference. A very positive user experience makes the difference even when the functional added value is lower: The convenience of digital solutions in online shopping, for example, leads users to order with one click and accept a worse price.
For companies in the premium segment, UX is indispensable. Users expect a positive experience with a brand's solutions — and are willing to pay for it. UX is equally relevant in the B2B sector: Here, the user experience directly affects the operating processes of professional users — their efficiency, error rate, and results. Whether clinical software, laboratory equipment, or process management systems: The quality of the UX determines whether a system is adopted in everyday work or forces workarounds. At the same time, the product is a central touchpoint to the company: Through use, users experience values and brand directly.
Examples: good and bad UX in everyday life and application
UX becomes most tangible when it is missing — or when it works so well that it becomes invisible.
At the ATM that refuses to dispense cash even though the account is covered, the interaction fails due to unclear menu navigation. In the office, employees book their times incorrectly in the time tracking app because the interface does not follow actual work processes. And in the dental practice, the specialist fails to activate the drill because the interface of the treatment system forces a sequence of steps that makes no sense in the treatment process. Three different contexts — everyday life, office, clinic — and each time the same pattern: The technology works, but the experience fails.
Good UX, on the other hand, is hardly noticeable because it simply works. A digital check-in, a baggage interface, and a seat display during boarding, each guiding through the step without uncertainty. A guided CT scan process where the system guides the medical staff through the process and ensures patient safety. Or an automated parental allowance application where documents are available digitally and the process is completed without paper piles and trips to authorities.
The difference: Bad UX creates friction, errors, and frustration. Good UX eliminates this friction before it arises. Beyond mere function, good UX can inspire and convey joy — most strongly where the product becomes the brand promise.
The disciplines of UX Design
UX Design is not a single craft, but an umbrella term for specialized sub-disciplines that work together:
User Research
examines the needs, behaviors, and usage contexts of users through qualitative and quantitative methods.
Usability Engineering
ensures that products are effective, efficient, and satisfactorily usable — in Medical Technology also as a regulatory requirement.
Interaction Design(IxD)
defines how users interact with a system: processes, transitions, states, and feedback.
User Interface Design
designs the visual layer — layouts, typography, colors, and information hierarchies — as an expression of interaction logic.
Industrial Design
brings in physical product design, relevant for devices with hardware-software interfaces.
Motion Design
uses movement and animation to make interactions more understandable and transitions smoother.
Service Design
is an independent discipline alongside UX Design. It does not focus on the individual product but on the entire chain of touchpoints between users and providers.
Design Strategy
anchors design-driven decisions at the enterprise level — from the Product Visionto portfolio development.
UX Design in the company: Methods and process
The UX design process follows the principle of Human-Centered Design and is typically divided into two core phases: Discovery and Delivery.
Discovery: Understanding what is really needed
In the Discovery phase, the right questions are asked. Qualitative interviews and quantitative surveys provide insights into real usage contexts. User Journey Maps reveal where friction occurs. Personas condense the insights into actionable profiles. In synthesis, patterns are identified and hypotheses formulated — as a basis for all further decisions.
Delivery: Making solutions tangible and validating them
In the Delivery phase, concrete solutions are created. Ideation and conception translate insights into wireframes and product concepts — as enablers for discussions between product management, development, and design. User Interface Design translates interaction logic into a visual design that reflects the brand. Prototyping makes solution proposals tangible and testable early on, without high development costs. And validation with users ensures that design decisions are based on observed behavior, not assumptions.
Maturity levels: How UX is anchored in companies
In companies, there are different maturity levels of how UX is lived and applied. The Danish Design Ladder describes four stages:
1. No Design (Non-Design)
Design plays no conscious role. Products are developed purely functionally, without regard to user experience or market orientation.
2. Design as Styling
Design is used at the end of the development process to make products visually appealing. The basic function is in the foreground.
3. Design as Process
Design is integrated into the development process and used as a method to solve problems and systematically improve the user experience.
4. Design as Strategy
The highest level: Design is anchored in the corporate culture and strategy. Designers work with the executive level. Design influences the business model and brand identity.
In German B2B companies, UX is often anchored at level 2 or 3: Design is used, but often too late in the process, so that relevant product decisions have already been made. How widespread this imbalance is shown by the McKinsey study: Over 40 percent of the companies surveyed did not speak to their end users during product development, and a good 50 percent stated that they had no objective method for evaluating their design work. Both explain why UX Design in many organizations remains below the upper levels of the design ladder. The decisive step is to involve UX early — as a strategic instance, not as downstream cosmetics. Those who understand UX as a tool of Product Strategymake more informed decisions and minimize misdevelopments. The podcast Behind the Screensdelves deeper into this topic in the episode on UX maturity.
What UX Design achieves
The impact of UX Design is evident on two levels: in the company and with the users.
That UX Design measurably impacts business results is empirically proven. The McKinsey study *The Business Value of Design* (2018) examined the design practices of 300 publicly traded companies in the Medical Technology, consumer goods, and retail banking sectors over five years. Companies in the top quartile of their design index achieved 32 percentage points higher revenue growth and 56 percentage points higher shareholder return growth over the five-year period than their industry peers. The study attributes this impact to four practices: leading design analytically, dissolving the boundaries between physical, digital, and service design, anchoring human-centered design cross-functionally, and continuously testing and iterating with end users. Remarkable for regulated industries: The effect was just as evident in Medical Technology as in consumer goods and retail banking.
Wirkung im Unternehmen
Those who understand early what users need do not invest in solutions that miss the market. Prototype-based work creates clarity before high development costs arise.
Prototypes create a common picture for product management, development, and design. Discussions become more concrete, agreements faster.
With comparable functionality, the user experience decides. UX becomes a distinguishing feature from the competition.
User-centered processes uncover needs that were not visible internally and open up new fields of offerings — the basis for a strategic [UX Product Vision](/ux-produkt-vision).
Wirkung bei Anwendenden
Products that are oriented to real work processes are accepted and used productively.
Clear, understandable interfaces lower entry barriers and increase willingness to use.
Intuitive products explain themselves. The costs for onboarding and support decrease.
Good UX not only relieves but also creates a positive experience — a factor that binds users to a product in the long term.
Users who experience a product as valuable and pleasant recommend it and become multipliers.
Where UX Design reaches its limits
UX Design is not a panacea. The discipline faces specific challenges:
Measurability
Years can pass between the use of UX Design and its measurable impact — the time of product development and the moment of customer enthusiasm rarely coincide. Additionally, users rarely speak of outstanding UX. They attribute their satisfaction to the product itself. UX merges with the product, and the absence of problems in use is not recognized as quality, even if it is a significant achievement.
Lack of understanding at the decision-making level
At the C-level and in product management, there is often a lack of a solid understanding of the value of UX. The consequence: UX is treated as an executing discipline, not as strategic.
Reduction to aesthetics
The widespread assumption that UX means "making things pretty" or "arranging buttons" underestimates the methodological core of the discipline and limits its scope.
AI expectation
The notion that AI can independently generate UX solutions and save costs is widespread as of 2026. In practice, such approaches fail because they are neither novel nor oriented to the specific customer problem.
How Splore understands UX Design
For Splore, UX Design means creating user-centered interactive systems that solve real customer problems — and make a difference through an outstanding experience. The focus is on complex B2B products in regulated industries: Medical Technology, industry, software.
What shapes this understanding is an attitude that can be described as a questioning mindset: the ability to systematically examine assumptions — at the beginning of a project, in the middle, and at the end. Is the direction still right? Are we solving the right problem? Asking these questions before high development costs arise is the core of what Splore understands as Derisking Development: minimizing risk through early validation with the people who will later use the product.
Splore combines Research, Interaction Designand Interface Designin an integrated process. How this interplay looks in practice is described by the UX Design Servicesof Splore.
FAQ
UX Design — User Experience Design — is the human-centered design of products and services. The discipline combines user understanding, business goals, and concrete product solutions to create a desirable experience during use. Its roots lie in Human-Centered Design: identifying real problems and designing solutions that are desirable, technically feasible, and economically viable. UX Design encompasses sub-disciplines such as Design Strategy, User Research, Interaction Design, and User Interface Design.
UX Design shapes the entire user experience: processes, interaction logic, information architecture, and whether a product solves the right problem. UI Design shapes the visual interface — layouts, typography, colors, and information hierarchies. UI Design is a sub-discipline of UX Design. Good UI without solid UX remains superficial; good UX without thoughtful UI loses impact.
Central methods include qualitative interviews and quantitative surveys in user research, User Journey Mapping and Personas in synthesis, wireframing and prototyping in conception, as well as usability testing and iterative validation in the testing phase. The process typically follows the Human-Centered Design approach with two core phases: Discovery (Understanding and Exploring) and Delivery (Designing, Testing, and Validating).
In the B2B sector, UX directly affects the workflows of professional users. Poor UX creates inefficiency, errors, and training costs. Good UX increases productivity, reduces onboarding costs, and increases acceptance among users. For companies with complex products — such as in Medical Technology, mechanical engineering, or industrial software — UX is a differentiating factor in competition.
As early as possible. UX Design has the greatest impact when integrated before central product decisions are made — not afterward. If UX is only brought in late in the process, relevant decisions have already been made, and the influence is limited to cosmetic adjustments. The Danish Design Ladder shows: The leap from "Design as Styling" to "Design as Strategy" only succeeds if UX is part of the development process early and continuously.
