ENTERPRISE DESIGN SYSTEM
Defining a Shared Interaction Contract for a Modular Fintech Platform.
Challenge
the same user action produced different system outcomes across modules
high-effort data could be lost in edit flows depending on the context
three validation behaviours for the same form type
duplicated interaction logic increased delivery effort
Role
interaction model for owned product flows
audit reframing from component library to interaction contract
design QA in Storybook and production
supporting adoption during feature delivery
Key decisions
edit mode as a protected system state
modal used only for irreversible user actions
submit always active with post-action validation
interaction behaviour embedded in component definitions
reusable cross-module interaction patterns
Impact
predictable and learnable product behaviour
platform-wide reuse of interaction logic
reduced handoff interpretation and rework
safe editing of high-effort data by design
