The starting point
Repeated needs revealed enterprise responsibilities
Business Applications repeatedly needed to identify calling systems, authenticate users, communicate through several channels, integrate with government providers, collect payments, obtain employee context, and support users.
These were not features of one Business Application. They were reusable enterprise responsibilities.
The architectural decision
Each capability received a clear owner
- AIS identifies the calling application
- SSO authenticates the human user
- Employee Services provides governed employee capabilities
- Notification Service owns communication channels
- Payment Service owns orchestration and transaction truth
- Government Integration owns provider connectivity and security
- User Support owns acknowledgement, assignment, tracking, and escalation
The result
Business Applications remain focused
Applications focus on presentation and business logic while consuming trusted shared capabilities. Providers, channels, and security policies evolve inside their responsible service rather than being changed everywhere.
Transferability
A responsibility model, not one organization’s screen design
The architecture can be evaluated against another government or enterprise environment and adapted to its identity authorities, payment providers, communication channels, regulations, and existing systems.
