Trinity
Design system strategy and governance across a fragmented logistics enterprise — one source of truth for dozens of teams.
Design system strategy, audit and governance framework for Hermes. Multiple product teams, inconsistent components, zero shared language — Trinity brought structure without slowing delivery down.

Scaling consistency across a fragmented ecosystem.
Hermes managed multiple digital products across customer, operational and logistics touchpoints. Different teams and agencies contributed to the same ecosystem. Patterns diverged. Brand guidelines existed. A unified design system did not.
As the product suite expanded, inconsistencies became more visible. Components were recreated across teams, interaction patterns varied depending on context. Each product functioned independently, but collectively the ecosystem felt disconnected and unreliable.
The issue was not visual polish. It was scalability. Without shared structure, delivery velocity slowed and design debt accumulated quickly.
Strategy
The objective was not to redesign screens but to introduce system-level governance. The focus was creating a shared structural foundation that would enable speed, consistency and long-term scalability across products.
Understanding the problem
A full audit revealed significant component duplication, inconsistent spacing logic and divergent interaction behaviours. Teams were solving similar problems independently. Without a common framework, effort was repeated and quality varied.
By analysing patterns rather than pages, the structural gaps became clear. The ecosystem needed shared rules, not just shared visuals.
Test or feature prioritisation
The system was built from atomic principles, focusing on reusable components rather than static templates. Foundations such as typography, spacing, colour and interaction states were established first. Governance documentation was introduced early to prevent drift.
Components were structured around real engineering constraints to ensure adoption. The system was designed to evolve without fragmenting.
Visual design language
Trinity introduced a consistent visual framework across products, aligning typography, spacing and hierarchy. Interfaces began to feel part of a unified ecosystem rather than separate tools.
Clarity improved naturally once structural alignment was established.
Design system
A shared component library reduced duplication and improved developer handoff. Shared interaction primitives meant consistency increased across products, and governance documentation kept the system honest over time.
The design system became infrastructure rather than documentation.
New features
As the system matured, new features could be implemented faster and with greater consistency. Teams gained confidence in shared components, reducing unnecessary redesigns and accelerating iteration cycles.
Velocity improved as friction decreased.
