Why invest in UX/UI?
Imagine a car without a dashboard, with unreadable controls. It may work, but no one would want to drive it. In the digital world, it’s the same. A functional but poorly designed interface comes at a high cost, for both your users and your business.
User experience is a true performance driver:
- *88% of users do not return after a poor online experience.
- 94% of first impressions are design‑related.
- Improving retention by just 5% can generate up to 25% more profit.
Beyond the numbers, a well‑designed interface reduces rework during development, lowers support costs, and strengthens credibility and brand image. Even for internal or regulated software, poor usability leads to time loss, increased support load, and reduced team motivation.

Project for chartered accountants
We supported an accounting firm throughout its digital project, from the creation of its visual identity (logo, graphic charter, branding) to the UX/UI design of an internal business tool. The solution was complemented by a marketing website to promote the firm’s services. Our UX/UI teams worked closely with software developers to deliver a coherent, functional, and fully integrated solution.
Design System for AVISTO
We designed and documented a complete design system for AVISTO, aimed at harmonizing web interfaces and improving visual consistency across tools developed within ADVANS Group. This centralized reference includes UI components, accessibility best practices, UX guidelines, and front‑end resources, making it easier for product and development teams to collaborate. It is available online to ensure smooth and widespread adoption.

Your questions about our UX/UI expertise – Answers from ADVANS Group
Frequently Asked Questions (FAQ)
Are you wondering about the technical challenges, key stages, or engagement formats related to UX/UI? This FAQ brings together answers to the most frequently asked questions to help you better understand our expertise, methodologies, and the solutions we offer.
Why invest in UX/UI
Why invest in UX/UI?
Investing in UX/UI helps improve adoption, reduce rework costs, and strengthen your product’s credibility.
A poorly designed interface generates errors, unnecessary support load, and user drop‑off. Conversely, good UX anticipates these issues from the design phase and optimizes return on investment.
Integrating UX/UI into an ongoing project
Can UX/UI be integrated into a project that is already underway?
Yes. Our interventions are modular and adapt to existing systems: UX audits, targeted recommendations, user‑journey optimization, or partial redesigns.
The goal is not to redo everything, but to quickly identify the highest‑value friction points.
Deliverables
What are the deliverables?
Depending on the project format and objectives:
wireframes, UI mockups, interactive prototypes, design systems, UX documentation, user journeys, personas, audit reports, test summaries, and prioritized recommendations.
Collaboration model
How does the collaboration work?
We work closely with your teams throughout the project:
scoping workshops, regular reviews, co‑design sessions, and a clear handoff to developers.
The process is structured, transparent, and designed to integrate seamlessly with your existing methods.
Project duration
How much time should be planned?
Our formats range from a few days to several weeks, depending on the level of support.
A UX audit can be carried out quickly to identify key improvement levers, while comprehensive support includes design, iterations, and user testing.
UX and internal tools
Is UX useful for internal tools?
Yes, and it is often underestimated.
Poor internal usability leads to time loss, errors, increased support, and team demotivation.
Optimizing user experience also improves operational efficiency and productivity.
Designer / developer collaboration
Can developers design the interface themselves?
Developers implement interfaces, but UX/UI design is based on usage analysis, ergonomics, and user experience.
Designers and developers work together: design guides development, anticipates technical constraints, and delivers added value from the very first iterations.
Use of AI in UX/UI
Do you use AI to design interfaces?
Yes, as a support tool, never as an end in itself.
AI can accelerate certain mechanical steps (exploration, variations, prototyping), but value always comes from human expertise: understanding users, business context, strategic choices, and UX trade‑offs.
User testing
Why carry out user testing?
Even with a strong understanding of your users, testing can reveal issues in just a few hours that might otherwise go unnoticed for months.
A limited number of tests is often enough to identify most friction points, with an excellent cost‑to‑benefit ratio.
If end users are difficult to reach, tests can be conducted with your internal teams.
Accessibility
What about accessibility?
We integrate RGAA/WCAG best practices from the design phase and can provide dedicated accessibility audits when needed.
