The present invention relates to multi-slice, multi-service-instance communication services, particularly to multi-slice, multi-service-instance assurance for Service level Agreement (SLA) and Quality of Service (QoS) requirement fulfilment. The invention presents a device for managing a service related to at least two network slices and to a corresponding method. The device is configured to obtain management data for the service from at least one of the slices, in particular one or more of the following: performance management (PM) data for the service, fault management (FM) data for the service, analytics data about the service. The device is further configured to evaluate at least one assurance indicator of the service based on the management data. Finally, the device is also configured to generate further management data, in particular configuration management (CM) data for modification of the service and/or at least one of the slices, according to the evaluation result.
