Engie / Design System

Create a complete design system for Engie, a French multinational utility company which operates in the fields of energy transition, electricity generation and distribution, natural gas, nuclear, renewable energy and petroleum.

• A lot of different teams and branches
• Big range of users
• Large spectrum of activity fields
• A lot of stakeholders and huge political blockers

To introduce a new unified design system across a company this big, we :

• Aligned all the stakeholders and built a vision
• Clarified the goals and the problems we are trying to solve with this design system
• Built a clear roadmap for the deployment
• Interviewed designers and devs to understand what are their expectations

In less than a year we successfully deployed this new design system :

• Introduced a common visual and experience language between designers and devs
• Resorbed a big part of an old technical debt
• Increased the velocity of the product teams
• Reduced the dev time by 20%
• Oboarded 6 teams on the project
