How we work

Clear answers to the questions brands ask us most often.

Usage before design

Good design starts with understanding usage. We ask, observe, and measure before designing.

Clear rather than creative

Interfaces may be attractive, but must first be understandable.

Accessibility

Contrast, keyboard navigation, and readability are included from the start.

Test early

Prototypes are easier to change than finished software.

Approach and decision criteria

  1. 01

    Initial meeting

    We clarify objectives, target group, and framework, and check what the website or shop must deliver.

    Result: Clear set of requirements.

    From you: Objectives, offers, and existing pages.

  2. 02

    Concept & Design

    Structure, content, and design are coordinated before development.

    Result: Approved concept and draft.

    From you: Brand guidelines, content, and approvals.

  3. 03

    Implementation

    Development, integrations, and testing, focusing on speed, accessibility, and measurement.

    Result: Testable version.

    From you: Access and a dedicated contact person.

  4. 04

    Launch & Optimization

    After launch, we monitor usage and results and make targeted improvements.

    Result: Ongoing optimization with reporting.

    From you: Feedback from sales and support.

Measuring success & limitations

Task success, dropout rates, and feedback show impact. We define in advance what counts.

Limitations: With UX/UI, results depend on content, offering, and maintenance. Good technology alone does not generate inquiries.

Questions before commissioning

What does a UX/UI agency do?

It researches usage, designs structures and interfaces, builds prototypes, and tests with users.

What is the difference between UX and UI?

UX concerns experience and process, UI the design of the interface. Both belong together.

How does the collaboration work?

Discussion, research, concept, design, testing, and handover.

Do you also implement?

Yes, upon request. More on our web development page.

How do you address accessibility?

We pay attention to contrast, keyboard usability, and readable structures, and check with common tools.

What affects the effort involved?

Scope of the interface, number of user groups, and depth of testing. We clarify this in the initial meeting.
