# Operational Considerations

This section covers following requirements needed to run the MOSIP–CRVS integration.

Use it to create the operational entities that CRVS-initiated workflows depend on (centres, machines, officers, and an application identity).

* [Create Centre](/1.2.0/interoperability/integrations/mosip-crvs-integration/prerequisites-configurations-and-operations/operational-considerations/create-centre.md): Create a centre to represent the physical/organizational location where CRVS operations are anchored.
* [Create the Default Officer](/1.2.0/interoperability/integrations/mosip-crvs-integration/prerequisites-configurations-and-operations/operational-considerations/create-the-default-officer.md): Configure a default officer for cases where the system needs an operational “owner” for a transaction.
* [Create Machine](/1.2.0/interoperability/integrations/mosip-crvs-integration/prerequisites-configurations-and-operations/operational-considerations/create-machine.md): Register a machine/device that will be associated with a centre for operational tracking and access controls.
* [Map Officer to Centre and Machine](/1.2.0/interoperability/integrations/mosip-crvs-integration/prerequisites-configurations-and-operations/operational-considerations/map-officer-to-centre-and-machine.md): Assign an officer/operator to the right centre and machine so transactions are authorized and auditable.
* [Create the Application ID (AID)](/1.2.0/interoperability/integrations/mosip-crvs-integration/prerequisites-configurations-and-operations/operational-considerations/create-the-application-id-aid.md): Create an application identity used by CRVS-initiated flows and integrations where an AID is required.
