Company: Tridonic, part of Zumtobel Group
Product: LITEKIT – Lighting Management System (B2B, IoT)
Market: Professional lighting industry, Europe-wide
LITEKIT is Tridonic’s flagship software, managing lighting installations across commercial buildings. Launched in 2014, it expanded reactively to customer requests, becoming a cluttered, inconsistent, and fragile product with limited scalability.
When I joined in 2019 as the sole UX designer, I initiated a full UX audit and redesign effort to address structural usability issues and realign the product with user and business goals.
A mission-critical tool with no UX direction LITEKIT was developed without a cohesive UX vision.
Each feature was a response to a specific client, resulting in:
• Confusing navigation and task flows
• Inconsistent UI patterns
• Unclear feedback and error states
• Technical limitations that hindered scalability
The result: a mission-critical tool that was hard to use, harder to maintain, and risky to scale.
• Initiated and led the redesign strategy
• Led a small UX team (2 designers)
• Conducted user research, heuristic analysis, IA, wireframes, and testing
• Acted as the bridge between users, tech, and business
Heuristic Evaluation
Using Nielsen Norman’s principles, I identified core usability failures. Key insights:
• Inadequate feedback during critical actions
• Multiple inconsistent interaction patterns
• High error cost in live environments (e.g. turning off lights in office zones)
These insights aligned dev teams around a shared understanding of UX debt.
Product Mapping
We built a comprehensive view of the system:
• Flow maps and feature breakdowns
• Cross-role dependencies and pain points
• Technical limitations and constraints
This enabled clearer roadmap planning and better stakeholder discussions.
User Research
I interviewed 6 users across 3 key roles:
• End-users: office staff using basic functions
• Commissioners: experienced technicians installing devices
• Facility Managers: responsible for energy optimisation and maintenance
Pain points identified:
• “Planning takes too long”
• “Installation testing is inefficient”
• “UX is the biggest blocker in adoption”
Competitive Benchmarking
I audited competitors’ platforms to identify UX patterns, positioning opportunities, and low-hanging usability wins. This gave our direction credibility with stakeholders.
Information Architecture Redesign
We restructured the app’s navigation:
• Grouped features logically by workflow
• Reduced visual clutter
• Prioritised high-frequency actions
Wireframes & Testing
We designed and validated:
• Map-based interface for spatial device management
• Bulk commissioning workflows
• Drag-and-drop for custom layouts
Testing with real users (technicians in-office) ensured alignment with actual field needs.
Final Stakeholder Review
We packaged the findings into a full proposal and presented them to product owners and tech leads:
• Research-backed prioritisation
• Tested solutions
• Strategic UX debt mapping
Result: Strong endorsement of the UX approach. But implementation was blocked due to architecture limits (15-controller cap).
Even without a rollout, the redesign achieved:
• A shared language for UX between teams
• Tools and artefacts reused in other products
• Sparked roadmap shifts toward incremental UX improvements
This wasn’t just a redesign; it was a cultural reset for how product, design, and engineering collaborate.
Not all UX work leads to a launch. But with the right framing, research, and storytelling, it creates internal alignment and product maturity that pays off long after the project ends.
Good design is not just what ships – it’s what transforms how teams think.
