Various arrangements for creating a slice on a cellular network are detailed herein. A cellular service request that indicates various metrics for a slice may be received from a client. A test function may be created on the cellular network based on the cellular service request. Via a radio access network (RAN) of the cellular network, access to a reduced-scale slice that provides access to the test function for a small set of user equipment (UE) of the client can be provided along with access to key performance indicators (KPIs) for the reduced-scale slice. The reduced-scale slice may later be converted to a production slice that provides access to the network function for a larger set of UE of the client.
