Before

‍
• ❌ No end-to-end design system existed
• ❌ Fragmented patterns across products and teams
• ❌ High risk of inconsistency and rework in a regulated domain

After

‍
• ✅ Layered, enterprise-compatible design system architecture
• ✅ Additive extension model (no forking, no overrides)
• ✅ Consistent, predictable UI behavior across surfaces

‍

* Complex, evolving data* Non-negotiable user research * Experienced, time-constrained users* New product + evolving design system* Limited capacity for rework

‍

* Standardize structure before screens* Define states once, reuse everywhere* Encode decisions into the system* Reduce cognitive and operational rework

‍

* Enterprise design system (base)* Project extension layer (additive)* No forking, no overrides* Designed to be promotable or disposable
