Business architecture
The capabilities the business needs, and which systems deliver each.
- Capability map
- Process-to-system mapping
- Ownership model
Solution Architecture
The target architecture for a payment estate — components, integrations, data flows and the non-functional requirements they have to meet — decided before the build begins.
What Solution Architecture is made of
Each module can be deployed on its own or as part of the whole.
Application architecture
The components, their responsibilities and the boundaries between them.
- Component model
- Build, buy or reuse decisions
- Vendor fit assessment
Integration architecture
How systems talk to each other and to the schemes, switches and banks outside.
- Interface catalogue
- Message standards (ISO 8583, ISO 20022)
- Error and retry design
Infrastructure & security
Where it runs, how it scales and how it is protected.
- Hosting and resilience model
- Security zones and key management
- Non-functional requirements
Where it sits in your estate
Starts from
- Business strategy and plan
- Regulatory requirements
- Existing systems and contracts
Solution Architecture
Hands to
- Delivery and implementation teams
- Vendors and integration partners
- Security and certification work
Questions buyers ask
Yes. It is designed to integrate with existing core banking, switch and scheme connections rather than replace them all at once.
