When companies implement ServiceNow, they often think first about workflows, self-service portals, and automation. But what is frequently underestimated: success ultimately depends on the integration of existing systems. Whether ERP, HR tools, or collaboration platforms – without seamless interfaces, the potential of ServiceNow remains unused.
Already in the planning phase, a central question arises: Which systems need to be connected – and how deeply? Not every interface needs to be implemented immediately. What matters is which data flows are business-critical, which regulatory requirements apply, and how much effort an integration will require.
Key Questions for Integration Planning
To avoid pitfalls, a clear set of guiding questions helps:
-
Which systems provide the data required for processes in ServiceNow?
-
Does the data exchange need to be bidirectional, or is read-only access sufficient?
-
What security and compliance requirements apply to the data transfer?
-
Who is responsible for operating and monitoring the interfaces?
-
Which processes benefit immediately from an integration – and which only later?
The answers to these questions determine whether the integration becomes a lean enabler or a complex long-term project.
Typical Integration Scenarios
Projects often show recurring patterns:
Data synchronization: Core data such as users, roles, or locations are regularly imported from HR or identity systems.
Process integration: Tickets, changes, or purchase orders are directly linked with ERP or ITSM tools from other vendors.
Real-time integration: Through APIs and event triggers, information flows between systems without delay. This enables faster responses but requires more effort in architecture and monitoring.
Hybrid approach: Some data remains in the source system but is made visible in ServiceNow – similar to a “virtual access.”
Challenges and Success Factors
Complexity increases when access rights and data models don’t match. In these cases, mapping or even adjustments to the source systems may be needed. Equally important: monitoring and error handling. Interfaces are only as good as their stability in live operations.
Best practices:
-
Build integrations step by step, starting with processes that deliver the highest value.
-
Use ServiceNow’s standard integrations whenever possible.
-
Establish governance so it’s clear who owns which interface.
-
Consider security and compliance from the beginning.
