There are many ways to set up an IT service management office, but all need to have these three key components: governance model, service structure, and roles and responsibilities.
The first step to setting up an SMO is identifying its need and the business objective it will serve. The next step is to hire customer service and support experts who can manage the SMO from its inception to its eventual operation. The last step is to implement the SMO by training employees on how it works, what its policies are, how it should be used, etc.
