Case Study – Building a scalable design system for a multi-brand HVAC ecosystem

CONTEXT

WOLF, a leading company in the HVAC industry (Heating, Ventilation & Air Conditioning), operates several digital products across two brands and three product categories — in total more than ten applications. The goal was to establish a company-wide design system ecosystem that ensures a consistent user experience across all digital touchpoints.

CHALLENGE

The main challenge was to align the diverse requirements of multiple product teams and develop a solution that could be efficiently integrated into products at different stages of development — from already live to newly started.

APPROACH

• Designed a scalable information architecture that allows future services and features to be integrated flexibly
• Developed an automated end-to-end design-to-development handover
• Introduced an incremental implementation approach focusing on fundamental components (e.g., switches, dialogs, buttons)
• Worked closely with product owners and developers to ensure seamless integration across all platforms

IMPACT

• Established a scalable design system ecosystem for two brands and three product categories
• Achieved significantly higher consistency and efficiency in product development
• Reduced maintenance efforts through automated token integration
• Created the foundation for a long-term, cross-brand design strategy
