  5G non-public networks (NPNs) play a key role in enabling critical Industrial
Internet of Things (IoT) applications in various vertical industries. Among
other features, 5G NPNs enable novel operation models, where the roles and
responsibilities for setting up and operating the network can be distributed
among several stakeholders, i.e., among the public mobile network operators
(MNOs), the industrial party who uses the 5G NPN services and 3rd parties. This
results in many theoretically feasible operation models for 5G NPN, each with
its own advantages and disadvantages. We investigate the resulting operation
models and identify a set of nine prime models taking into account today's
practical considerations. Additionally, we define a framework to qualitatively
analyze the operation models and use it to evaluate and compare the identified
operation models.
