Assuming configurable workflow rules eliminate integration work
FIS ties onboarding and servicing to payment and core processing updates, which increases implementation effort when core and payment changes are tightly coupled. Temenos and Alkami also use deep configuration, so coordinated testing across channels is still required to prevent workflow behavior drift.
Choosing event-driven automation without planning for workflow ownership and monitoring
Unit reduces polling by using webhook-first lifecycle events, but advanced automation still needs disciplined workflow design and monitoring to keep downstream actions consistent. Tuum and FinTechOS can reduce custom polling, yet governance ownership still determines whether lifecycle handoffs remain stable.
Delaying permission and role design until after workflow configuration is built
Mambu’s RBAC coverage varies by operational role, so permission design must be addressed early to avoid onboarding or servicing actions failing silently. Synctera supports audit-friendly lifecycle handling, but engineering time for admin and workflow configuration must be budgeted for end-to-end journeys.
Treating UI journey orchestration as equivalent to operational orchestration
Backbase can coordinate onboarding journeys with workflow-ready screens, but deep customization increases integration and release coordination effort. FinTechOS automates approvals and notifications tied to state transitions, so teams must validate adapter arrangement for core banking depth.
