The installation and implementation was done by the vendor, not by someone from our company.  

We didn't hire a consultant or integrator. We handled the solution's implementation ourselves. It's fairly easy. We didn't need help.

SIU assisted with the setup. If the solution would have had better setup support, we wouldn't have needed them.

On average, it takes two junior-level engineers to deploy and maintain this solution. Generally, the clients do the implementation themselves.
