Overview.

GE Appliances operates across a complex ecosystem of digital surfaces, including the SmartHQ mobile app and ROUX, the Android-based interface used on physical appliance displays. Each platform supports multiple brands with distinct visual identities while sharing core functionality.

As the number of supported products and brands grew, inconsistencies in layout, spacing, accessibility, and component usage began to compound. This work focused on establishing a more rigorous design system to improve cohesion, accessibility, and cross-team alignment across both SmartHQ and ROUX, while enabling teams to scale without increasing UX debt.

Designing for Scale and Consistency.

SmartHQ and ROUX were both evolving platforms supporting many brands and devices. Design decisions were evaluated based on how well they could scale without introducing fragmentation. We impletemented Atomic design rules to build up our responsive interfaces.

Establishing Shared Foundations.

Grids, spacing, typography, and component behaviors were formalized to create a common language across teams. This reduced ambiguity for designers and engineers while enabling more predictable implementation.

Accessibility as a System Property.

Accessibility considerations were integrated directly into components and layout rules. Truly implementing based on the curb-cut effect, touch targets, spacing, contrast, and hierarchy were refined with the understanding that accessibility improvements benefit all users through clearer, more usable interfaces.

New Screen Ideation and Design System Integration.

New screens were explored through rapid ideation to test how the design system performed in real product scenarios across both SmartHQ and ROUX. These explorations helped validate component flexibility, hierarchy, and accessibility rules while revealing gaps and edge cases early. By designing within the system from the start, ideation work directly informed system refinements, ensuring new features could be introduced without breaking consistency or accessibility standards.

Supporting Future Growth.

Tokenization research and system documentation were explored to support future brand differentiation without duplicating effort. The system was designed to evolve incrementally as products and requirements changed.

Impact Summary.

This work helped establish a shared foundation for designing and scaling interfaces across SmartHQ and ROUX. By introducing clearer standards, improved accessibility practices, and stronger system-level alignment, the initiative reduced fragmentation risk and enabled teams to move faster with greater consistency.

Business Context.

At GE Appliances’ scale, design systems play a critical role in reducing operational friction. Clear standards improve communication between design and engineering, lower rework costs, and help ensure new products ship with consistent quality.

A scalable system also protects long-term usability as the platform grows, enabling faster prototyping, more reliable NPI integration, and more consistent accessibility across brands and devices.
