Flexible configuration

From UX down to the core, the product offers composable and pre-configured services across three primary components to help accelerate transformation:

  • Experience orchestrations: blueprints for financial activities and customer interactions
  • Business orchestrations: standard business workflows supporting essential bank functions
  • Domain connectors: resilient API adaptors to core platforms, internal systems and the FinTech ecosystem

Domain-centric and standards-based

The experience and business orchestration services are designed in accordance with the Banking Industry Architecture Network (BIAN) standards, a world-class reference point for interoperability in the industry. These services are hyper-contextualized and product domain-centric for retail and commercial banking.

Orchestrations are defined through distinct configuration-driven parameters rather than being hard-coded. Abstracted from the core, these services help enable maximum reusability, prevent vendor lock-in and eliminate the complexity of legacy IT.
