You'll need a team of four or five people because there are several components, such as database, storage, and networking, and all have to be aligned. But their roles depend on what you want to do. If you want a single administrator and separate and define several roles depending on if you want a system administrator on one side, active directory on another side, or packages on another side, then their roles depend.

We implement this solution for our clients.

We outsourced the implementation to a consultant. They were very good and knew exactly what to do.

I was an assistant administer before for 10 years. So all these products have gone through my hands. I know them all. I have clients and consult with them on their deployments. Some have already deployed SCSM or I may have clients who are looking to implement SCSM in their organization. I have to evaluate what each type of client needs and make appropriate suggestions. I deploy myself because I have the hands-on experience.

We implemented the solution ourselves.

We are consultants and help clients handle the implementation of the product.

Our internal IT department is in charge of implementing and maintenance of this solution.

It was implemented in-house and the only valuable advise is to plan, again plan then do, check and then act. You need to know how many users, what roles, what services, SLAs, tiers, members, and distribution lists because SCSM works with AD DL`s for allocating roles.
